I have a sundown x10 d4 in a 2.0ft^3 box tuned to 31 hertz. I have been searching for an amp to run this sub for the past 2 months and can't come up with anything on a budget. My budget is about 400$ and I would like to put 1500 rms on the sub at 2 ohms. I have a second alternator to just power my system it's just your average 150 amp with a run of 1/0 sky high to a xs power 975. Anyone have any suggestions for an amp?
