Just made a new box and got a new amp and now one sub is playing fine and the other cuts in and out. Any ideas? I'm running 2 kicker L7's and 1 kicker amp 1200.1

recheck the wiring and also your grounds

I checked the wiring. But how would the ground affect only one of the speakers?

I dont know bro, just the first thing that came to my mind to check

I'd take the sub out and look at it. One of my infinitys was doing that and it turned out that one of the wires on the sub had broken loose. It was cutting in and out for a few days and then it just completly broke off. If you're sure your wiring is ok, then it sounds like something is up with the sub.

Also could be the output on the amp itself. Mine is in the shop right now for that very issue.
My passenger side speaker worked no problem, but the driver side cut in and out, and over the course of a couple months would stay off longer and longer until it didn't work at all anymore.

its a mono amp, it has one set of speaker terminals. If that were the case, both subs would be acting up.

yea it is a mono amp and when the speaker cuts in it sounds like crap, but the other one that always plays sounds fine.
