What is an amp that goes with an Alpine SWR-1522D subwoofer? Do your own research for the specifications?
the kicker 750.1 would be a good choice because the rms of that sub is 750 but the kicker would push a little more than 750, but the type r should handle it just fine. another amp would be the Hifonics TXi7508 but tou would need the dual 2 ohm type r 15 to do that with the 750.1 you would need the dual 4 ohm version.
