Aftermarket Radio

[2string]

Has anybody installed an amplifier behind the back seat of a 2003 ext. cab? Just wondering if there's enough room back there, also does anyone have a JL Audio stealth sub that they would like to sell?

I was thinking about it after I swapped the OE radio for the Pioneer but have not got around to it, there seems to be plenty of room under the seat and if I were to go mega cool I would possibly turn the bench seat into a pair of buckets and have all the amps and woofer box in a center console and etc.
BTW if you have Onstar you can still get an adapter for the Onstar to voice over the speakers, Crutchfield and Ebay has them. I didn't need Onstar so never connected it back up.

I have an amp and sub under the back seat of my ext cab. I also believe there is room behind the backrest if you want to mount it on the back wall of the cab. I havn't tried it though, so don't quote me on that. I might one day if I have some free time.

Ya that's what I was wondering if it will go behind the backrest. I'm pretty sure it will fit but I am worried about it breathing and overheating. I am thinking snow could get on it under the seat, also I want to put a sub there and I don't think 2 amps will fit with a sub. rjeffery,what are you using for a sub?

[rjeffery]

I have 1 10" Infinity Reference in a single box. It puts out way more bass than I need.

Well I looked up your sub and only found a speaker, no box I was wondering how it was installed under your seat? I've been looking at the JL Audio stealth.

I have the Infinity Reference door speakers (front & rear) too - they sound real good.

Here is the sub: http://www.infinitysystems.com/car/p...=US&Region=USA

This is the box I have: http://cgi.ebay.com/ebaymotors/ONE-1...QQcmdZViewItem

The box is just sitting on the floor under the seat.

That sub looks like it will do the job I don't pump the bass a whole lot anyway and the price is right. I'm not sure how there measuring it do you think it will fit under my seat I have an 2003 ext cab. Is it rectangle or a wedge? Does it stick out at all where your feet would go? Sorry for all the questions.

I have 3 amps behind my bench seat. You can mod it to fold down pretty easily. I have 2 12s under the seat in a downfiring box that i made. Here's a pic from when i had 4 amps:

It is a wedge and it fits under the seat of my 02 just fine. You can measure to make sure. It does stick out a little bit, but only a few inches.

Nice setup. Is that a bottle of liquor behind your seat too?...

all nice set ups here, I got a friend with the 03 extended cab, he put 2 infinity 10's in a custom box under his seat with the subs facing out, I belive his amp is inbetween the subs under the seat, works real well.

Much easier with a crew cab , i use to have that piss poor custom box for behind the read bench that held 2 12''s...that lasted about 2 or so months, so I unbolted 2/3 of the bench and put in a huge custom box w/ 2 12''s , $20 for the 3/4'' MDF sheet, $100 for the amp, $75 for 2 12''s with S&H, enough bass to visably shake the windsheild wipers.

If anybody wants that custom box pm me ill give it to you for free just pay s&h, just taking up garage space now.
