Wow a memphis. This is an oldschool amp line. awesome amp, but i have found one a little better for a lot better price. planet audio is the answer. i have two. the biggest of my two is a 1250.1 that pushes two kicker 15" l7s. and on top of that is a 6 year warranty. and to top it off runs 350$ and less.
the memphis is a better amp, you can find used 1000d which is a 1100w amp for about 200used, either the st series or the mc series, the planet audio is made by the same people that make Boss and Soundstorm.
