Im about to get a new system in my car, im getting 1sundown sa12 4ohm as for the amp i was thinking of either an Alpine MDX1100 rated at 1100rms at 1ohm or Boston Acoustics GT-2200 which is rated 900 rms at 2ohm. Both ratings are at 14.4v and are CEA rated. Any suggestions or previous experience with either amp? Im trying to have good SPL and SQ. Thanks!
