I have a problem, my subs are hitting weird, as in a constant beat not to the music, but they still hit on the bass. I had previously cut the rca jack wires and hooked the wires up to my speakers in back. Finally decided to run them to my stereo, so I had to splice them back together. Is this a problem, like will it somehow mess up the frequency, or might it be my amp is messed up? Any help or advice is appreciated. By the way, I'm only using 2 channels on a 4 channel amp, is there any problem with this either? Thanks.
