sub bass cuts down

[g0t-milk 10+ year member]

ok once again im having a problem. i re mounted my ground to somewhere more stable, electric sanded it to bare metal.. i mean its BARE.. so it cant be ground. re checked my sub wiring, its fine. got a new amp, the kicker 400.1 -- moved my rca's all around, attatched the 5ga power wire directly to the amp (was fused to dual 8ga on the other side of the fuse block, i had 2.. one by the batt and one by the amp) and still my sub bass is dropping. it will hit hard then sounds like half the power has been cut... then it will kick back in again. ive checked a shit load of things.. only thing left i can think of is put a different power wire in, or check the head unit for any loose connections. any other suggestions you might have? it happens alot.. but mostly when i go up hill or downhill is when the bass kicks back in, or if i hit a bump. so if that happens, its gotta be a loose wire, right? on the inside of the box from the sub to the terminals i just wrapped the wired onto the metal securly, no connectors.

Sounds like you need to solder. That will prevent your problem in the future.

sounds like ur sub might have a problem

yea i was thinking it was the sub also, but it did this before with my last 2 setups. and different amps. so i cant see how it would be the sub

doubt it is, ive tried 3 different places for ground. i get power.. so i dunno. right now its in the best place its been in since ive installed it.. im going to move it to the bottom of the trunk next time if nothing else works before i check my hu wiring

You might have a problem with the RCA outputs on your cd player. I have fried a pair on my first pioneer cd player. You can take it to any audio shop and they can check it to see.

RCA's would just cut out completely but u might be losing a sub....I'd go new RCA's or try a different HU. Solder all connections.....wires to terminals, HU wires.....its much more secure and prevents loss of power, signal etc.

^ try another cd player like he said

Could be the amp. Your sub could be ******* too much current and cutting the amp out. That's happened to me before with my old RE HC on my buddies amp.. which escapes my mind

Does this happen at all volume levels or only when its really wangin

I have to say i don't agree with the post above (well 2above) because I ran a crappy 400w max 2 channel on a pair of xplods and never had a problem. try another HU or check the rca input on the amp, it might be loose.

Dude, xplods are a piece of ****ing shit. They draw as much current as I produce rubbing a balloon on my head.

and the one sub is going to draw more current than 2? uh? don't think so.....not out of a kicker amp.
