Default Possibly a BC 2k amp problem.

I'm having a problem with my bc2k. I'll be driving and playing music and the sub amp will stop playing. It won't protect, it doesn't get hot. Its wired to 1 ohm but I don't think thats important. When it stops playing and I hit a bump or road reflector it'll start back up. I can be sitting still and it hasn't done it. Thought it might be something to do with the subs wiring, but i've redone it. Had it mounted on the box for less than a month and it is no longer on it. All the checking i've done is, Checked the subs wiring, checked the rcas going into the amp to make sure they were tight, made sure the remote was in good. I've alread heard that "it was because it was on the box and something rattled loose". Checked that too and nothing on the inside looks or feels loose and no burns or anything. I have shook the amp and hear no rattles. Thoughts??

i would still say it is from being mounted on the enclosure.

Of course, But why isn't it protecting? Why does it just start playing when a bump is hit? What part of the amp could have been loosened?(sp?) I thought the amp would protect if any part that had electricity running through it came loose or failed. Wouldn't that be the case? Or maybe the RCA imputs are bad?

When my dc 2k did his it was because the rca's on my HU were going out an I had to ground them to the HU. It's worth a try just to eliminate that suggestion ou of the way.

Will try this, Its a older HU anyway. Only problem is the RCA's outputs on my hu come out on cords. Its a alpine 9813. I'll definatly try to do something with that though. thank you.

If it happens with a bump can you replicate the problem by wiggling or bumping the amp any? Did you check voltage at the amp on both power and remote when it happens?

I have tried hitting the amp while it was playing. I have not checked either. I have got the remote going from hu acc. to 4-channel then from 4-channel to mono. I don't have a voltmeter hooked up yet.

I know right? I just tried hitting the top part of the heatsink. I guess i'll try some more in depth bumping later.
