Still need to clean those wires up man. And you actually have both subs hooked up to each channel? How much can those subs handle? And what is the amps Bridged rating?
I had boths my 12's bridged off a little 120 watt amp. Had it running at 1 ohm. Might be able to do the same to yours, if the subs can handle it. If your really looking for some more power out of it. Just suggestions.
