This is real nice!

I bought this amp to push 2 12" Apline type E's. They bump like no other. I was very impressed with the crisp, clean sound of this amp. I HIGHLY recommend this amp.

Okay

I have this thing hooked up to a Rockford 10" P3D2 which can do 400 rms and 800 max in a sealed box sound comes from a eclipse cd 3000 all the wires are high dollar Rockford and I also have a cap wired in and it sounds like my sub is under powered but other than the power for me anyways its a good amp.

Can't Go Wrong With Alpine

I got the MRP-M450 from my local shop. I have it wired to 2 S-Types at 2 ohms in a custom Sonic sub enclosure. Unbelievable how well this little amp pushes two subs. AWESOME!

Alpine Amps are the way to go!

I just purchase two of these. They are pushing two Alpine 12" type-r Subs. trust me on this even with a default gain from my amps, I can feel some serious thumpin'. check this: we turned the gain, bass eq, and the filter all the way over, i had my cd player on 4! (not able to hear ANYTHING out of my speakers) my subs were MOVING! I would HIGHLY recommend this product to anyone either looking for some serious bass or a lil' something to stir some dust up from a classic.

Good Amp

I purchased this amp along with two 12" Alpine Type E series subs. I have a Pioneer DEH 4800 pushing the factory speakers in my explorer with the amp pushing the 12s in the back. The whole system sounds really good. I can turn it up and there is no distortion at all. The bass is not muffled and sounds good. I am very pleased with my purchase. You will be too.
