I recently had my engine worked on and dropped from the car and ever since this has happened my front 4 bose speakers havent worked (i unhooked the rear sub because it was blown). i have an aftermarket head unit and an amp powering 2 10" subs. when i power on the head unit my "stereo accessory" fuse blows immediately. i have no sound coming out of the front 4 speakers and only sound comes out the subs. i dont know if a wire was hooked up wrong in the engine bay or not the guy just told me he had grounding problems when hooking the engine back up but got that figured out before i picked it up. this is the second head unit i have hooked up with this problem so i know its not a faulty head unit and all the wires are correctly hooked up to the head unit.

anyone ever had this problem?
where should i look first?
what does the stereo accessory fuse control?

also my stereo fuse is fine and never blows which is why i am confused.

 

are you using a converter for the bose amp or did you run new wires. bose amp is different and will not like getting power from a aftermarket stereo.

 

are you talking about the bose amp that runs to the back "sub" speaker? or is there another amp that runs the front 4 speakers? cause i had an aftermarket stereo and it ran perfectly fine before the engine was removed.

 

yours is different than mine. i have/had two front, two back and one base. i had to get new speakers and wire. crutchfield recomended i change all of it when i went with the amps and all. said the speakers i had where for a different setup and wouldnt work right with a aftermarket unit.

 

Sounds like you have the 5 speaker Bose system. There are 3 amps, 1 on each of the door panel speakers and one for the sail panel speakers and woofer.

Are you using the Bose amps or is everything being powered with the aftermarket amp? Delco-Bose amp is a low impedance and level system which requires a converter box to match the stock outputs if you choose to use an aftermarket stereo (Bose is 2 or 4 ohms as opposed to the standard car audio 6). If you're using a different head unit with a Bose amplifier then it's sending to much signal and could blow the amps. I had to use the OEA-4 adapter to make everything sound right and have linear volume control (however, that Scosche box is a POS and I don't recommend using it).
