quick info; running 2-12" infinity subs with coustic 600se amp, 150x2

today, i was driving with the backseat down and noticed one of my subs weren't going off.. so i just finished re-checking all the wiring in the box, did the battery test (one wire on + the other on -) and there was movement, so i'm thinking one of the RCA's in behind my deck came loose? what else should i check for?

once again, thanks for sharing the knowledge

 

Swap the rca's at the amp, if the same sub is still dead and the other sub is still moving, then you have blown a channel in the amp.

 

will do tomorrow morning when i tear down the dash.. much appreciated
