SPL GLA1-4500D

Awesome amp. It destroyed my 2 power acoustik 12s. Not the mofo 12s but the cheaper ones. It's very strong, I never put it on an amp dyno but it gets the job done and doesn't get overly hot. It played well wired in 1ohm and like I previously stated it broke my subs. Feed it the right power and it will do the job and do it well.
