Memphis amps are some of the best on the market.
Which model are you talking about?
Could it be the MC1300D which is known as the Memphis belle? If so then it is rated at 1100x1 at 1ohm and 75x4 at 4 ohms.
The also make a 1500D which is a mono block, this amp is rated at 1500 at 2 ohms. The 1500D I don't think can go
down to 1ohm.
They make a 1000D which makes 1000w rms at 1ohm.
Anyway you put it Memphis makes bad ass amps.
Impressive....I am running 2 of the memphis 1500d's at 1ohm, haven't had any problems other than a blowen altenator.
