how can we test the speakers/amplifiers on the Bose system? It seams like they all took a dump at the same time... can ALL the individual amps die at the same time? Its not normal... it has an aftermarket CD player... it works but there is no sound at all from any of the speakers...

when I disconected the amp and jump the feed straight to the speaker... barabin!! it worked!! but nothing from any other speaker...

At 160.00 each amp? Are u kidding!!

Please advise...

thanks.

not sure if you want to , but I removed the bose , installed a sony, no more amps, antenna only goes up when the 'radio' is playing, stays down with everything else, better sound than the 20 year old bose, and only cost $200 and bout half a days work for the head and 4 speakers.

Highly unlikely (almost impossibly) all 4 bad at same time. And that is not the usual symptoms anyway. Squeaks, sequels and muddy sound are the common complaints.

The speaker amplifiers need 12 volts to operate and sounds like you might have lost it. It comes from the Bose relay (feeds all amps) which hangs on the wire harness near the receiver/ preamp. The voltage comes from fuse 37 so check that first. The relay is controlled by radio head and the receiver. The radio head sends the signal to the receiver to close a switch and then voltage from fuse 4 goes to the Bose relay and turns it on (closes it).

You may have a bad ground or bad connection in a connector also.

I had the same problem. Turned out to be a loose wire!!!
