Default Car Audio Gods Hate me...troubleshoot help...

I finally got everything working with my budget setup and everything sounded pretty darn good the past few weeks until I started having a strange problem. I don't even know where to start troubleshooting.

Everything was working as it should until the other day it seems some strange signals are being sent to my subwoofer. It is an intermittent problem and it comes and goes. It sounds like there is a low frequency popping or burping that happens. It will play for for a long time and only happen once or twice, it can be a pretty constant occurrence, or may not happen at all on a trip in the car. The signal is only being transmitted through the subwoofer as far as I can tell. The volume of the signal does not change things. It will happen with the volume on very low (but the popping will be at a much lower level). For example, I could be listening at a level of "1" and the popping will be very loud. If the music is loud, you might not even notice it if you aren't paying attention to it.

I know the sub can't play a signal it is not being sent, so the signal is coming from somewhere. Bad signal from the HU? Bad amp?

JVC DVD HU
MB Quart Onyx 600.4 amp
Pioneer Subwoofer

Edit:
I was playing with the RCA inputs and something odd happened.

My HU is a 5 channel so it is a single channel out to the sub. I put a Y-adapter off the sub channel and ran the RCA back to the amp. If I plug both RCAs in I get sound. If I only plug in Channel 3 (with either RCA lead) I get sound. If I only plug in channel 4 (with either RCA lead) I get no sound.

Could this be the problem? Channel 4 is not working?

Hmm...this one could be anything really. Bad RCA's, amp is starting to fail, make sure the bass boost on the amp is at 0, hu not functioning properly, loose wire/ connection somewhere...

I had something like this happen with a mtx amp years ago. Ended up being bad ground connections on the rca input. Temporary fix was to ground the input rca's to the output rca with speaker wire. Its crap shot but sounds kinda the same.

Unplug RCA's from amp, turn volume up and see if that thump comes out your subs. If it come back it's your amp. Leave your speaker wires in, just unplug the RCA's. I had this happen to me a few years ago ended up being faulty amp.

If it doesn't come back with RCA's unplugged, get a known good pair of RCA cables and swap them.
