Hi, I have a 1600 watt Audiobahn mono amp powering my 2 10" Infinity Subwoofers. When i put my volume up to the max the subs are making miniscule amounts of sound/movement. I think that the amp is getting underpowered because i have a 4 guage power wire coming into a capacitator and a 0 guage power wire going from the capacitator into the amp. Could this be the reason why the subs aren't very loud? If you need more details i can try my best. This is my first system so not very acquainted with all the terms.
