i have a 98 blazer and i was wondering where is my factory amp for my stock ac delco radio. i wanted to put a stock bose radio in my truck because i know they put out more but will i need the stock amp for that bose radio to get the same quality the bose should have. please any help will be great. also the 2 speakers on the drivers side in both doors back and front dont work for some reason any suggestions? thanks

 

my factory amp was in the rear passenger side wheel panel

 

In my 96 I have the same issue with speakers that you have, only on the passenger side. I just ordered all new Sony Xplod 4-way 6.5s last night, so i'll let you know what the issue was when I install them later this week. If you still want to know.

 

If you don't have a Bose system now, you need the Bose amp as well as the Bose head unit.

 

Well, installing the speakers was a breeze. I guess just both on that side were totally blown, because they worked without any problems. Also, I would recommend just replacing your head unit with a different aftermarket one. My guess is that it would be more trouble than it's worth to add in the 5th and 6th speakers up front on the dash, and connect them all into a separate amp, especially since i know those stock speakers won't handle as much as a separate amp would throw at them. What I did is throw a Sony head unit in so as to control my ipod, replaced all four stock speakers with 300 watt Sony's, and got an Infinity Basslink sub to put in the back. It sounds glorious. Also, I've heard the Bose system before. Doesn't even come close to my setup, and I only spent around $400 for everything.

 

I have a 86 s10 blazer..... no sound from the rear speakers, I replaced the radio, the best buy tech told me there is a factory amp...does anyone know where it is?

 

I don't see anything on alldata as far as an amp on an 86.

 

does it show a common connection for the rear speakers....I have no sound but the speakers test ok. neither side work aand I just installed a new radio.
