I believe I have discovered my problem, and I'm an idiot not to have thought of it. Simply, I wondered if my amp could not handle the wattage of both my subs, so I unwired one and it works perfectly, with or without high gains and boost. So, I have a connector to wire up another amp in the back. Question is, would I have to run another wire to the battery?
