1985 T/A 5.0 4BBL LG4. My Car has the performance sound option. Behind my sail panels I have what look like custom boxes, with a 4x6 and what looks like a 4.5 or 5.25 woofer. Is this the stock setup for the performance sound option? Also there is a Switch on the dash panel with a slider. Stock Amp Turn on and Gain(where is the stock amp?) With the stock deck it seems to work. With my aftermarket deck I'm not getting anything. Even though I spent the money on one of those wiring harness adapters. Stereo will play but the amp button does not seem to work. What Gives? I love this site!

 

ok , that setup is stock , i had it in my 85 trans am , the amp is lockated above where a passenger would sit in the front seat . their is an access panel and then its under there . It shouldnt work because the stock stuff is like 8 ohms and the aftermarkets stuff is differnt . they had to run new wires when i had an aftermarket cd player put it .

 

Thanks for the info! Your car is hot man! What did you pay for your ram air hood?

 

18inchboyds, the amp wouldn't happen to be a small black box bolted onto the panel behind the storage pouch on the passenger side, would it? I had to remove most of the interior panels to fix a problem I was having with the headlight switch, and I couldn't seem to identify what that thing was.

I don't have the performance sound package, though.

 

thats where my amp was , i cant think if anything else is under there , but thats where my amp was. Well its still in there .

THe hood cost around 600 shipped , this was back in 03 so it might be cheaper now .

 

its not the computer, is it? that's exactly where mines at.

 

yup i just found out that if you have the performance sound option you get an amp right behind where the ecm is. i attached a pic...

 

That's an aftermarket amp in that pic--not factory at all.

 

factory amp

 

that would be cool if there was enough room to mount a real amp in there... but I've never seen a good amp that small.

 

Does any one have a wiring diagram for the factory amp.
My 89 Firebird does have one but I want to install one.
what are inputs on the factory amp? Is it just the channel inputs coming from the stereo?

Thanks,

its a delco amp

 

what kind of power would you see with an amp like that? and would the headunit of a car with an amp have no internal amp?
