Sub suddenly doesn't work anymore. AGGGHH!!

[Johnny Utah]

Forgive the long explanation.

I have been running my sub (Pioneer TS-WX80) off my JBL GTO755.6 Amplifier (6 ch) along with some rear infiniti full range speakers. It's been working fine for a year at least. I turned my van on one day and the sub stopped working.

I have checked that the leads aren't a problem. I also checked the full range speakers through the sub output on the amp...they get sound.

I tried the sub through the rear speaker output on the amp....stilll no sound!

I figured that the driver in the sub must have gone, so I replaced the speaker w/ a Pioneer TS-SW841D.....but, I still get no sound.

I even tried connecting the speaker cable from the amp's sub out to the terminals on the speaker itself rather than the enclosure's terminals and I still get nothing.

Is it possible that the amp doesn't have enough power to run my sub(500w max)? Could it be a grounding problem? If the full range speakers work on every channel of the amp, then surely it must be the sub at fault right?

frequencies crossed over wrong?

Unfortunately I don't know anyone with an amp in their car. I take it there's no way to try at home on a home stereo cos of the different impedance right?

I don't think it's a crossover thing either. The crossover is internal in my amp. There's a small freq range to sweep but i tried that. Plus the full range speakers worked out of the sub outputs and distorted because of the amount of bass.

so it worked for a year like it was and then stopped without you changing anything? you could test the sub on your full range speaker outputs and if nothing then it's the sub
