No Navin; I wont suggest this for kb as he wants a very decent setup and already has 2 ID subs waiting to be installed. He can afford buy a good 4 channel amp. And hence kb,why this question? why why!

I would dump the sony amp. (you can courier me the amps you dump ; free )

[navin]

2 ID subs. In stereo these would be better off with a better amp than the 275. I'd consider a bridged Blau 4120 or something like that or atleast a bridged JBL 75.4.

Then he can use the 275 for the front (not the best use for a 275) and the 222 for the rear.

The 275 is really nice a mono sub amp but KB got stereo subs. There in lies the mismatch.

[jkdas]

I know this question was asked before..but forgot where it was...so

What should be bought first? Amp or Speaker?

and for one who wants a good install, dont you think a seperate mono amp for his sub would be nice?

[Sam Kapasi]

Well, here's my 2 cents now.

Though often it's the front end which most useful and provides the maximum satisfaction, some people have been known to derive pleasure from the rear end too.
I believe the front can be cleaner, sweeter and (as the name suggests) more upfront too, but eventually it's upto the individual. Also the front end will provide results that are more visible. But of course this depends on the persons needs and taste again.

With the right settings you can use the front end when needed and shift to the rear when required, depending on the situation.

[navin]

A good 5 ch amp can drive a sub and 4 speakers but they are few are far between so it if often easlier to use seperate 2/1 amp and a 4 ch amp for this install.

However KB has 2 ID subs. That means either he either uses a big mono amp (like the JBL 600.1) and uses both subs in mono or use a smaller 2 ch amp and uses stereo subs (and in the above case I even suggested getting a smaller 4 ch amp and bridging it into 2 channels to drive the stereo subs).

All components should be bought together.

KB - will there be space for passengers after all this equipment is installed? We'd like to listen to this sometime, y'know...

[rsjaurr]

poor Kb,he is very confused man right now........ this is very much expected if someone is going for high-end ICE.Same happened to me as well when i was going for my ICE.I dint know what all to buy.

my experience with ICE tells me that u should go for rear coax as they cost nothing as compared to total cost[navin said it in post 192].To me raer spk r much more than just rear fillers especially if someone is going for two subs [that too ID subw]so that bass doesn't overpower mid and low freq sounds.

For such high end spk,subw and HU,i wont recommend using some sony amp or even blau.Best for u would be to go for one 4-ch decent amplifier and a powrful mono amplifier [rated atleast 500.1] just for two subs.DONT EVEN TALK ABOUT USING HU'S INTERNAL AMP TO POWER REAR SPK IN UR SETUP.

and i agree with navin that whole set-up should be bought/decided togehter.Even if someone is going for phased installation over a period of time,he should have finalised his final ICE.

An excellent website where the Tru Tech T03 4.150 amp and its qualities/uses are much discussed (search the forums):[COLOR=#0000ff]Elite Car Audio [/COLOR]online forum

Gunman and JB are the authorised distributors and this is what they add...

So when Tru says its a 4x150w amp, its all a big joke, these amps put out even more than double those figures.

The rear two channels of this amp is going to [power the 2 iDQ10 subs IN STEREO (....THERE.. thats settled too!! )

Now perhaps the rear fill/imaging question makes more sense..

And of course... my feverish quest for getting this right...

Rudra spends insane amounts on Cameras, you spend insane amounts on Amps.

Is there anyone that spends insane amounts on cars ?

As JK asked, where do you park?
