Its a overall effect...when the car feels good the sound will be good too..hehe

Added on March 22, 2012, 3:13 pmMy ie core transformer prototype arriving this week...so excited.
Its for custom power supply, able to generate 260v dc 5 ampere for tube preamp car audio usage.

The whole core is soaked into lacquer.

it seems that most if not all head units really have lower power internal amplifier, mainly because that is supposed to be a job for an external/add-on amp. because mostly, the head unit limited space, 1-DIN.

now there are some cars who have 2-DIN slots. is there a head unit that has powerful amps enough that is stored on the 2nd DIN area?

the usual higher amp head units like most Alpine and some Blaupunkt have 18W RMS only. Pioneers even have lower, only 14W RMS. I think the OEM head units are even lower than that.

i've seen JVC KW-XR416 has 20W RMS, its 2-DIN and costs below RM400. i saw an old model Alpine CDA-9815 (can MP3 but no USB) that has a V-Drive MOSFET that delivers 27W RMS for a 1-DIN player.

the most i knew is the Alpine KTP-445 which is an add-on for compatible Alpine head units, which upgrades the output to 45W RMS. but it think that one is not cost efficient since it would cost like another head unit.

i wonder what is a quality head unit that is 2-DIN and uses the space it has for a better amp?

no matter how many rms a 1 or 2 din can generate, it will never exceed 45rms as the heat dissipation issues....just get an external amp and save the money on other items....those pnp amp are not cheap to play with compare to their performance....

^ this. that's why its normally opted to just get an external amp and get over the speaker driving power requirements.

i'm a bit interested in these things now, mainly not much about the money. its about the space, and elimination of an amp. thanks howie for the small bit of info you give me, i really learned alot from you. whenever i have idle time, i read on these things now.

just a quick check. Can a 4ch amp run both front comp and a sub?

well, if u really wanna save space with some decent sound, check out my blaupunkt amp that are plug and play with ur car

Added on March 22, 2012, 4:08 pmdefinitely yes, that's what i gonna do to your car later

thats what i am running on

thx!

Simple question, how much you bought for the p99?

I dun think there's any 2din that will outperform a similarly priced 1din. and any internal amp will NOT outperform a dedicated 50w rms external amp. Go try howie's 30w blaupunkt if you really wanna save space. but seriously there's no diff between a 4X7in amp and a 8X6in amp under the seat.

900 for ameron component?
Soft vocal? Same here.
Get the new p80prs instead, i think it is more than enough for normal ice player~

What?? 900 for ameron components?? Where u buy it bro? Is this model have motorised panel? If got, it will be a must have one

Added on March 23, 2012, 10:52 amIf I change my Saga stock speaker to a good ones first (Front n Rear) without changing my HU, is there any different in sound quality performance? If got, how many percent?

This post has been edited by geniuz: Mar 23 2012, 10:52 AM

30-50% depending on the speakers

Wow!! Thats great!! but what kind of speaker it is?

This post has been edited by geniuz: Mar 23 2012, 12:47 PM

63.27%.

please provide specifications, definitions and formulas on how did you concluded on the value "63.27%"

Have to ask him la bah, even my cap-ayam component is only rm499 ~
U mean p80prs? Dont know lea, have to ask unker howie, if u confirm take this hu, remember to inform me, i want audit

Change speaker? I would say 40%, another 60% is after u change to a good hu, and after some.... tuning(erhrm)..

Over a year back. Got it at sgd1300+-.

Added on March 23, 2012, 10:41 pmFrom my installer..
It's a plain silver speaker w/o any logo. Not those with Ameron logo printed on the front. Those rm200-300+ can get already.

Added on March 23, 2012, 10:46 pmBefore I purchased, I've compared price with Singapore, same set cost sgd4++. So I got at rm900 still slightly cheaper.

So.. Now, how is your setup actually? P99 plus ameron component plus .....?

4cha+2cha+mona block+cap+3"mid+12" sub.
P99 connected to IPod Touch.
SP: 3layers for 4doors, 2layers for floor, A-pillar, B-pillar, arch wheel.
Replacing current amps, sub and cap. Still hunting..
