I was wanting to get a 5 channel amp to run my system. Here are my choices.

KICKER KX700.5
Alpine MRV-F450
MTX Thunder 895
PHOENIX GOLD Octane-R 9.0:5

The pheonix gold says it has the most 4ohm power but what do you guys think? They are all about the same price so that is not the issue. I need an answer pretty quick.Thanks, scott
