Amp problem
I think after four years of faithful service my Sub amp may have croaked.
I originally had it wired high level to stock HU via the rear speakers and it has sounded GREAT since day one. I recently installed a new Pioneer 8000BT and wired it with RCA cables for better control and SQ. It worked great for a week.
The other day, my wife disconnected the box for more cargo space and when she put it back in, this problem arose.
The Amp is a Lightning Audio LA150.2 driving two ten inch Lightning Audio subs BRIDGED in a Q logic sealed box. I don't remember the specs on the subs.
The amp never went into protect mode. The only thing it did was before I turned the gain down, the power light went out, yet the illumination still was on. I cycled the power and it came back on.
As you can see in these videos, the volume on the receiver is low, yet the subs are at full blast with what I think might be some kind of feedback.
Things I tried were:
I wired up each sub individually both bridged and stereo and got the same results in both subs.
I also disconnected the RCA cable and hooked my high level harness back up and I got the same result which I think rules out a bad RCA cable.
Any suggestions before I scrap this amp? I know Lightning Audio is lower end, but this setup has been GREAT for almost five years. I had to trash it if its something I can fix on the cheap.
