Hi, I just bought a new pyle subwoofer with a power akoustic amp. I changed them because my last setup was acting strange. I put this new system in and it is doing the same thing and I can't figure it out. i redid all the wiring and i got new rca cables. The fuse is fine. You can feel the signal coming through the sub and you can feel the sub vibrate a little but its not hitting at all. I redid the remote wire too on my headunit. Please tell me what you think it could be and what I need to do to test.
