Still using the old Alpine HU 9807 ~_~... now my new plan to do some upgrading...
Me, thinking about buying ... (coz some1 offer me )

1. Alpine MRP-F240 V-Power Amp
http://www.alpine.com.au/products/product4.asp?id=161
I hope this amp will connect to my front 5-1/4" Speaker & rear 6" x 9" 3-Way Speaker <== Alpine
(i) should i change front speaker to Component 2 Way Speaker....

2. Alpine MRP-M350 V-Power Amp
http://www.alpine.com.au/products/product4.asp?id=163
(i) eeeh still looking for a sub-woofer & a box ~_~.. need recommendation.. maybe Alpine woofer again ...one 12" woofer should be enough for me
(ii) According to alpine .... 350W x 1 RMS [2Ohms @ 14.4V (1% THD)]... 200W x 1 RMS [4Ohms @ 14.4V (1% THD)]
Does it mean i only connect connect one woofer only..if so where do i get 2ohms woofer ?_?
(iii) Assuming i gonna buy one 200RMS woofer will the Amp destroy it ?_? wut about lower 150RMS woofer or higher 250RMS woofer

Since i'm driving nissan sentra sedan ..... should i go for sealed-box or ported-box..

I love to hear rock music ... then... anything which is audible

Need advise from experience user......... thz in advance....

1) connect the amp to the front
rear speaker power by HU power

2)i will go for sealed box...cos as i know ported box need more power to drive it

Well... i just cant wait & i just bought those 2 AMp


With Rm1600... i got 2 Alpine Amp & an Alpine woofer ..... sounds reason able to me

Tomorrow , i gonna find some 1 to install for me..... i cant wait


oops i just notice where should i get a sealed box ? buy or build

Do i need a Farad ?

About cable wut to buy @_@

erm..no comment on how reasonable it is
since u have bought it

installer u have to find urself...but let me know where u r then i can recommend some decent installers to u

where? some of the installer does this box building service

farad? u mean a capacitor?

cable ? budget pls

dump those 6x9 speakers since u aledi got alpine subbie, 6x9 will kacau the sound front change to component la, back 6" mids = all alpine (consider all ori la )

This accecesory shop i go .. willing to let me use ported enclosure 1st (ready made) .. if i dun like always can go back to exchange another 1 or custom build ....

Yeah I mean Capasitor... when do i know i really need it.....

Cable.. i assume they re using normal cap cable .... i saw streetWire but really pricy

i will stick to 6x9 for few days......... if the sound really kacau i will dump 6x9 to my another car, corolla.

I really though about component Apine sp171a....... selling for RM5xx
if i install the component set in front ........ it doent make sense i put my rm5xx speaker at the bottom of front door panel (original speaker space) ..... but my feet dun have any ears
Any solution to improve it.... unless i change car .... i just remember i folow my frens car is LandRover.. i noticed the original front speaker mounted at the middle of the door panel..... wah so nice .. i hope i can do tat 2

mwahahahahahha........ of course u only have 2 ori ears, not at ur feet

as long as it's in front

if u wanna custom made the bracket (fiber) also can, if u want the speakers as close as possible to ur lovely ears

u will need a caps if ur system is having 1000 RMS power or ur car battery has not enuf voltage
1000 RMS power will need 1Farad
2000 RMS power will need 2 farad and so on

streetwires are good cables
they have entry level stuff also

and about the comp pointing ur leg
dun worry
if it's pointing to ur ear..u will have ear pain
another good speaker placement is actually the kick panel which will give a better staging than placing it at the door panel

i quess i dun need any Farad at the moment my monoblock only 200RMS

"if it's pointing to ur ear..u will have ear pain " u sure kah... i though our pc speaker also facing toward us ........

i recall i ever heard annoying tweeter placing at front.. why it's so sharp till so irritating .. me not sure whether it's directly connect to amp or part of the sub-somponent. i hope i dun encounter the same problem when i buy sub-component next time.

while typing.......

Kring..kring ... the shop just call me , my car is ready .. i cant wait to hear it
Nice talking to u all ...... let c how does it sound like ...... i assume i'm an intermidiate user from today onward

the power of pc speaker is just merely 3 RMS watts
moreover the car environment is much smaller
the ambience will be more

OMG........ i dun know wut to say .......

Good news : Sounds lot of better after install Amp ....... The music & voice more clear .... The Sub-woofer more powerful

Bad news : More configuration at HU & AMP ... which are really confusing ... sometimes i may think the sub-woofer is too powerful for me which i not used to it. (must be trial & error)

1) How to balance Bass configuration..
e.g At HU got subwoofer output volume & Bass filter with db
At monoblock Amp got gain , db & filter

3) I should have place my 2 Amp at the back of my car instead of underneath my car seat... i find it difficult to check my AMp Hopefully some 1 dun spill any water & destroy my Amp

" Alpine is Good but the owner is a super NOOB " tat's how i see myself at the moment.

if u feel ur bass is too strong
see how much gain u're on
try to lower it

bass freq set to cut off at under 100hz

i wonder is Alpine MRV-P345 the latest one? I was quoted RM1200 for this 4channel unit

Why don't you just get an a/d/s/ top-of-the-line PQ40.2 rated at 100w x 4 @ 4 ohms to power up everything? Bridged 400w x 2 @ 4 ohms.

I've one for sale (new) at RM2500 neg. Market price was RM11k. LOL. Seriously!
