I recently bought a 500w Visonik amp on Ebay for like $12, and I let my buddy use it for awhile. It worked awesome for him, but he bought a new one, so I got it back. Yesterday I bought 2 Rockford subs in a Q-Logic bandpass box that sounded AWESOME with this amp. Now I got it hooked up in my trunk, everything should be perfect, but not only am I lacking a little bit of power, but my rear channel has static crackles in it when I get it above halfway up (Only when the outputs are plugged into amp.) I hooked my RCA's up into the rear channel, just spliced them into the rear speaker wires. Everything is all straight and that, so where is the static coming from? Do I maybe have one line in switched? Could that cause a disurbance? Both subs are in phase, or so it seems, so other than the thought of having one input wrong, where else could the problem begin?

Sorry to double-post, but I had another question. I have a Scoshe FAI-3A line convertor that I had in my old truck. I only used it for a few weeks, so I never got to know it well, but can I make it work without it substantially lowering the voltage coming from the head unit? I read that it basically strips the power, leaving only a light current to the amp. It seems it always works better when not using the factory outputs and the like. THANKS!
