I have a 98 Eldorado ETC....... I just changed out a Bad Radiator and now There is no sound from any of ther speakers. The head unit functions fine. Nothing else in the car seems effected. I disconnected the battery for about 3 hours to change out the Radiator. Nothing else electrical was touched. HELP???
Fuses are good. Any Suggestions??? I'm thinking Bad Amp...... The confusing part is the service manual show a Stand alone amp. and Amps at the speakers???

Solved it....... Pull both the Radio and Amp fuses in the rear truck area. Check to see if they are blown. Both were fine, now it works!!!!

 

See if codes are stored, post if present.

 

Can

 

To clarify, BOSE uses a PREAMP to feed the individual AMPLIFIERS (AMP) at each SPEAKER.
As many speakers as you have, you have as many AMP units.

I do not understand the solution .. could you expand as this may help someone else?

Also. can you pull the codes? They should be listed as "history" if you had any.

thanks
