Bose System

[A.Ciccone]

I bought my 1994 J30t without a functioning sound system. The Bose stereo has no response to my inquiry for music at the push of the power button. I've checked fuses, I've checked wires. I've taken the head unit in to get checked,and it's supposed be working just fine. I've been told the speakers can blow an amp and the whole system goes. Is there a way to just swap out some parts and allow those tympanic domes to breathe life once more or am I looking at having to take my poor J30t in to get jerry-rigged with some wal-mart grade crap?

The Bose sound system (actually a Clarion head unit branded Bose), has been a weak point the J's since new. They're known for simply quitting after working fine the previous day. Mine was replaced under warrranty twice. Was the Bose system tested in another J30 to ensure that it works?

are you actually getting power to the headunit?? like driverdriver said, these headunits have always been problematic. after i got my car, the radio lasted for about 5-6 months, but that was cuz it was pretty much garaged for about 6 years of its life. the amps have been known to blow, but i dont think all 4 would blow at the same time. i just recently lost my front passenger door speaker due to the amp. haven't gotten around to fixing it yet.

You can get to the rear amps through the trunk and take measurements with a voltmeter and the fronts are easy to test once the door panel is off. Amps burn out one at a time and losing one isn't going to take out the entire system. If you're convinced that all 4 amps are shot and not the head unit you might try replacing just one for starters. I have a few amps left if you want to do some testing.

The head unit's not getting any power. Would the speakers still read something on a volt meter even with the head unit being unresponsive?

A failing head unit will do all sorts of weird things or nothing at all.

And a lot of this seems to apply:

I had mine repaired by these guys:

Individual amplifer boards are prone to failure, the rears probably more than the fronts, early years more than later years, and I've thought about relocating my amplifier boards off of the speakers, where they'd be subject to significantly less heat, moisture and vibration.

Your amps are going to a good home and my snipe bid was a lot higher than what proved to be the winning amount. Thank you!

I could wise-up and give-up on the OEM system, but it sounds so good when it's all working properly. Extended periods of non-use seem to cause more failures than everday use. Local Pick 'n' Pull prices have run $5 per ampflier board over the years, and after the $2 admission fee to as many yards that you can get to in a day (3 or 4 in these parts).

I actually took a loss on the auction. It ended for 7 cents and I only charged 10 for shipping. It cost me 10.50 to ship

Good to know they are going to another NICO member!

That's why I always put a reserve of just enough to cover my tail.
