Today i bought a nakamichi 10inch 900w, rms 150w underseat active subwoofer.
Total cost rm850 including installation and tuning the subwoofer.

My setup.
Kenwood BT304 headunit
Front speakers Alpine SPJ-161C2 type J, coaxial 2 way speaker
Rear speakers Swissline 6x9 2 ways speaker
nakamichi NBF10.2A, 10" 900w, rms 150w underseat active subwoofer

Improvement.
Clearer vocals. Clearer voice clarity since now my front speakers not overworked. Bass become subwoofer job. The bass...omg got the clean tight punch DUB DUB DUB tight tight punch. Can feel the bass punch your buttocks if u sit at the passenger seat. Me likey. Not like cheapo subwoofer BOOM BOOM BOOM muddy punch..like the m*Q super cheap underseat subwoofer.

Overall..very syok. No more distortion unless i push the volume to almost max which is very very loud for me anyway. Totally worth the investment. Next upgrade is to install a full range 2" tweeters at the dashboard and my setup will be complete, for a budget setup at least.

Breakdown cost:
Headunit rm195 (lazada)
Alpine front speakers rm199 (lazada)
Swissline rear speakers rm220 (shop)
Installation and wiring 1 (headunit, front and rear speakers) rm250.
Nakamichi underseat active subwoofer rm850 (include installation and tuning)
Total so far RM1714

wrong subforum

oh wait

Mana ada wrong. Kopitiam is my place to log all my car's modifications.

Can ask how to get clearer radio channel ? Anything I can do to improve it? Honda FC

If your external antenna no issue and no wiring issue, and you are using an aftermarket headunit, then you can read on.

I tried going to a car audio shop and complain the same thing to them about my FM signal being weak.
One shop told me to install a FM booster, so I bought an FM booster.
It didn't improve...at least for me. RM60 including installation.
So sad with my wrong investment, I went to a few other shops and just talked to them while hunting for my subwoofer or amplifier (I haven't made up my mind which to buy that time).
Many say it depends.
Only one guy told me its useless. It really depends on your headunit integrated signals, meaning you need to change headunit. My problem also came when I install my aftermarket kenwood headunit.

Your neighbor no complaint?

you can install the antenna that stick on the rear/front windscreen.
last time my wira stick that and improve my radio receiption tremendously

nakamichi car speakers, kalau car always jemu kat panas, or no sun protection, will not last.
kalau nak good sound woofer, recommend box, not active sub type. oso, must hv good amplifier.

Same as my previous MTX mercury component speakers. X jemu panas pun, but before warranty finish both speakers problematic already. The glue peeled off.
Somemore mine is confirm original MTX.

My antenna already very panjang at outside of car wor...

I good boy. Also its not behind car big box subwoofer where whole car shaking (LOUD) and outside can hear clearly.
Mine is just tight bass and a bit loud. But outside not so kacau except if beside my car when my volume over 20. sorry la motorcyclist

I’ve upgraded mine too. Blam Signature component speakers, Venom amp and underseat woofer, door sound proofing, tuning.

headunit very important, must get those slightly expensive type. some branded/nonbranded cheapo version, will kira nasib.

kenwood should be ok..my headunit is Kenwood..support apple car play and android auto

How subwoofer make voice clearer? You still send same sound to front speaker. You change the Equalizer ?

Kenwood HU only RM195? Link pls

TS enjoy how many hours in car per day ?

Wah yours considered mid high range already.
How much total costs? RM5k?

Yeah spent quite a fair bit, 6.2k 😅

Bought last year during lazada promo. Now no more this price.. shopee now is RM298.

Johnkok must be proud

Previously my front speakers need to handle low end bass also. So my front speaker not getting enough power from my HU (no external amplifier). So sounds more teruk lo.
Now my active subwoofer has its own amplifier built in, so it handles all the low end. My front speaker only handles high and mid. So my HU still can supply enough power to the front speakers, but still not enough for full volume. Full volume will have some clipping sound, if your ears sensitive you can hear it. Clipping sound means not enough power supplied from HU to speakers. But now the quality for the loudness I required is more than enough for me, so I'm satisfied.
This is what I understand from the installer la.

sometimes no drive also.
But now when want rempit, I put eurobeat I can jizz already. DUP DUP DUP DUP!!

Spend so much already, upgrade la the stock HU. sure make difference

You buy and ask them install, or you bought all from them? Can breakdown the cost ah?

the signal no longer send very low frequency stuff, so yeah clearer output for mid and high range, this doesn't matter much if you have good amp.
Bass unit no need to produce very low range frequency, so it could focus on producer higher bass frequency sound

Bought from a shop and they installed for me.

Don’t want to touch HU as my car is using canbus system controlling other functions for the car and car still under warranty.

Blam Signature component speaker 3k
Venom amp 1.5k
Venom underseat woofer 1.5k
Door sound proofing 200

How does front speaker suddenly handle high and mid?

I can understand it doesn’t need to drive the subwoofer. But at the same volume setting, isn’t the same power and music (high, mid, low) is sent to front speaker?

The only way you make it clearer is by adding filter to filter out low signal to front speaker.

Why suddenly install subwoofer, the HU automatically send only high and mid to front speaker? Is there a setting in the HU that does that?

this part, that's where the tuning comes in and they work their magic ma. I not sure sure about this part tho.
But probably you are right, maybe they "filter" the low signal to front speakers. so front speakers only driving high and mids, so become clearer now

How much the shop charges you for all the cables, workmanship, installation and tuning?

for kenwood and jvc, you have this settings to filter out low range frequency, e.g if you choose 150hz, 0-150hz will not be send over front/rear speaker wire.


here a better settings explanation.

Oh, you are into tuning car audio too?
I don't know much of these things, so just pay people to do for me

underseat sub will never have the real thumbing bass of ported woofer box. owned a few under sub due to space issue.
under sub is good for those guitar basses higher low cut frequency, never can produce those real low's with "wooof woooof wooof pump"
under seat sub punch is quick and tight knocks but too boomy when comes to the music 2nd bass.
like a music example electro or trance when the 1st bass hit is a boom sound right? and the right after that 1st boom sound will comes the 2nd bass which is the something like a reflect back organ bass right?
that 2nd bass reflects always plays too high from an underseat sub caused very boomy..
something like a music bassline sounds like this "boookkk whunggg, bookkk whunngg, bookkk whungg"... that bookk is 1st bass, that whungg is 2nd type of bass, and it's that whungg whungg sound comes too high from underseat sub very irritating

TS which shop you went for the installation?

Oh nice. Better than crappy original hU BY Perodua

I not so much into wooooof woooof woooof pump.
I am more into DUP DUP DUP pump. to me this is tight punch.

Or you have and example of a youtube video to demonstrate what you mean?

no la, i am someone who not prefer bassy setup or someone targeting more treble sound
all my car speaker handle all those frequency range, so there is tuning being made.

Min Zone at Bayan Baru.
You are into ice too? What are you planning to upgrade?

Oh you play SQ. I also like SQ la, like the voice clarity, but also prefer the DUP DUP DUP bass.
So imma kinda SQ and SPL a bit.

yeah a good HU can set all the high cut and low cut vs slope frequency pass to each channel of speakers/audio output, must also depends on your front speakers high cut frequency range start from which Hz, and that HU need set your front speakers so that don't sent the frequency that your front speakers can't handle, this will result your front speaker can focus on playing very loud mids and highs without getting distorted because the heavy bass beyond it cant handle is not sent to it.
too much heavy bass send to the front speakers that it can't handle beyond its range and if it plays too loud will caused it to distort sounds something like "ffrttt frrrtttt frrrttt" something like bocor angin lol

yes bro underseat sub is DUP DUP DUP type sound tight, ermm well yeah can say it's suitable for u tho since u said don't prefer those wooof wooof wooof pump

thinking to get an Android player though..

Means your aftermarket hu is problematic?

Yes I’m still using standard factory HU. If need to change I will pass leh, will void warranty 😅

Install voltage stabiliser eg. Pivot megaraizin, gugel shopee got rm40

in your old nissan serena?

PS: real lalabeng. :x

Its time to get ur amoi to wet the front seat

did you change your light bulbs to LED one?

Underseat woofer will be abit underpower wo .. and the bass not so accurate one ..but of coz its a good upgrade if no sub.

it kinda wrong la say after put subwoofer suddenly ur front speaker become clearer... even thou it happened that way..

my guess is,

whoever install ur HU did make some adjustment to boost the bass on ur front speaker. then u pasang kuat2 until the speaker semput2 clipping. u should lower the bass setting if u like to listen very loud.

when u install the underseat sub, the installer reset back sound setting on ur HU, from flat perhaps he just slightly up the tweeter freq a bit. then direct all the bass freq to ur sub.

thus u hear the clearer effect. which u can gain urself by adjusting ur HU without adding the subs but then no bass sound la.

rm850 is a lot of money. on used market can get decent amp + 12" sub + wiring & upah pasang. lagi syok ohh.

If seldom in car why need buy sound system install it ?

Sentra b13 only. Not serena

Yeah kinda overspeat a bit haha. Nvm la as long as i puas. Actually i just want the blaupunkt gtr 110 sub, then kena poison by nakamichi sub. The shops i went to say nakamichi sub bass tighter. Then test two namamichi sub 8 inch 80w rsm and 10inch 150w rsm. 8 inch is ok but it looks puny..so for just extra rm150, ok la take the bigger one. I will swap it over to my proton x50 when i buy it next year anyway. Now monitoring x50 fb page see got major problems or not for 6 months to 1 year

Oh yeah i want my boot space. Weekends i transport stuff to and from my laundry shop.

Because i syok and can. Lol. Weekend time i will balik kampung, so that time i wan enjoy my music

How much will tuning cost?

I am not sure ne...i paid rm850.

Lazada rm600 + delivery rm10 + wires, fuse i need rm40.

So its rm200 for installation and tuning. But this guy memang tune la. He sit inside very long in the car and quite a few times he change my sub and my hu settings. And the whole time i was there so yeAh he not just sleep in my car during the tuning.

blaupunkt used to be a decent brand long time ago but now went downhill. as for nakamichi i dont think its made in jpn anymore. brand wise should be better than blaupunkt. thats why i always opted for oldschool stuff usually made in us or jpn. much cheaper than latest stuff made in us/france. but used item comes with reliability issue. nasib la. also i like to diy my own system.

for non diy-er like urself, & summore happy with ur buy, good la. summore can save boot space.

my 1st time into car audio. go kedai accs that ppl recommend, spent 1.5k for HU, front coaxial, 4ch amp & 12" sub. its loud but the quality so-so nia. even the power cable from battery not even pure copper. its the sampah copper clad aluminium (CCA). just recently found out after i dismantle everything.

im a bit skeptical bout this but i'll try to keep an open mind since my kenwood HU radio signal also so-so nia. wonder it can cure it.

u mind telling ur experience wit the product?

somehow the fm radio becum clearer

Rm200 sounds about right since installation + tuning. installation kuli biasa bole buat but tuning must at least audiophile kinda guy. usually the bos / owner or seasoned staff. it really took sometime coz need to match the clipping point between the sub & speakers. summore need to tune the sub to sound like its coming from the door speaker/everywhere. if u can locate the subs location when listening to music, the installer fail big time. for me this is the hardest task to achieve. be it in car audio or home stereo system (bookshelf speaker + sub setup).

perhaps the voltage stabilizer circuitry really lower the noise level coming from the alternator. thus making the signal clearer. since its cheap, i might try it. thanks for the input.

im thinking to do the BIG 3 or 4 upgrade. using pure copper welding cable is the cheapest solution. most people who did the upgrade said can feel the different in power. smoother ride & less or no noise signal at all. need to fork rm100-150 for big ass pure cooper cable & lug. then sendiri pasang.

why underseat sub? but not that enclosure type? slim type laa i mean.

u no choose that?

Yeah sony and blaupunkt went downhill already. Since i am not buying high end stuff, i choose nakamichi je. My iniital plan is cheapo blaupunkt sub, then uprade to blaupunkt gtr110, but the installer said the blaupunkt gtr110 some have issue of sapping the car battery so he no longet take in the stock.

Mine also is sampah aluminium cable huhu. For that price...i dont think can expect full copper la.

Yeah tuned by the boss. The anak buah do the installation. And yes the sub sounds like its coming from everywhere hehe.

honestly i cant afford audio grade oxygen free copper (OFC) cable. 1 meter 4awg size already cost rm40-50 brand biasa2 oni. after long research on net, i decided to buy pure copper welding cable 00awg size rm23 per meter. big ass cable. almost like getah paip air.

its not super flexible like the audio cable but the jacket/skin got double layer. can stand high heat. too bad malaysian welding cable not yet move to ofc standard like usa. anyhow, for the size & price, damn worth it.

congratulations.. seems like the boss really do his art of tuning.. happy for u..

Nowadays generation still got boom boom in the car ah? I thought that trend pupus already long time ago. Last time i can see almost everywhere techno song banging in the car till the booth banging grr grr grr grr hahahahaha

Not booom booom la. Mine is DUP DUP DUP sebiji sebiji one. Makes the music better in fact. If you crank it up, can feel the beat until your heart

I think needs 3m only kot. But nah lossness for aluminim+copper audio cables are around 15-20%, pure oxygen free copper is around 1%.. boleh la aluminlum also as long as my ears are happy haha

Yeahhh thanks~~

mine js the wira those long antenna on top of driver door. still not good

hmmm...then I might try la. plug and play?

I spent much installed Morel speaker, woofer and such. sekali tukar piping rempit. now all i can hear is praaaang. no longer can enjoy terresa theng in the car hahaha

My piping also around 2.3 inch wat. Still can enjoy and the sound can feel difference before and after.

if sub for own comfort rich bass then ok lah, puas dengar till own heart beating, but some fellas put sub like the booth wanna fly off LOL

TBH i dont know how they tune their subs,
i used to have a 1.2kW (yes, 1200W Boston Acoustic amp) with a 12inch matching sub + passive radiator, i can crank it up till the extent that's unbearable and it's only barely audible outside the car

There are actually people who believe in oxygen free copper

Do explain why u think aluminium wires brings no benefit than using oxygen free copper?

I believe in normal copper. I don’t believe in “oxygen free” copper. Lol

I see. Yeah to me copper and oxygen free copper technical has difference but its tooooo little to make any difference in real life

IIRC, you need to double the size of CCA for the same performance on pure copper wire. u also get twice the heat from CCA. every strand of CCA wire made from aluminium. only the outer layer of each invidual strand covered with copper. so CCA is a big no-no for me.

but if ur ears are happy, any wire aso can la..

you need amp to drive your front tweeters and mids? then head unit drive your rear 3-way? correct?

No amplifier. headunit driving both front and rear speakers

Not worth

speaking from experience i used to drive my speakers front and back, using a pioneer HU which if i recall cost around RM600 , and that was over 10 years ago.

with your cheapo HU, it wont be adequate, why not spend 200-300 more for a amp. i bet the difference will be huge.

agree that the woofer is too expensive, personally i would spend a bit less for the woofer and get an extra amp to drive the speakers.

one more thing i want to add, a proper 10 inch subwoofer , plus the vented enclosure, plus an amp, added up also around RM850. thats the setup i would choose.

Yeah, but if ts want space, active subwoofer is fine, just that i definitely would not hve gone for that brand at that price, i would have gone for the jbl basspro 8 active subwoofer

This post has been edited by Arvinaaaaa: Nov 15 2020, 09:31 PM

TS what car

If buy yourself RM600 only my sub.
will transfer this to my X50 when the time comes. So buy a bigger sub to cater for the bigger X50 cabin.

Sentra B13. But modded already to 225hp with 2.3 inch exhaust. So needs better speakers

Bro, for x50, i highly recommend the jbl basspro hub, quite expensive but damn good and space saving

This one will take up my spare wheel space le.
And it costs 3k...too much already. Already double the price of my whole system. lol

Wont take up the spare wheel, the speaker is placed into the spare wheel.

btw u can try this free 3d surround apps, really amazing effect on ur car speakers especially on tweeters n woofers
