Personally i would go with somthing underrated than overrated. The T1000bd might cost more but its a much better amp. Amps are fan-cooled and can run@ .5ohm daily.
the kicker would be fine as well, but the RF has a better retail value and lots of other things. If you cant find one used then go with the kicker. But a SAZ-1500 if you could get a good price on it would be awsome!!!
