    I have 2 of these. This is my 1st time ever buying car audio. I was looking around and that and what these amp have, they hit my SWR-1221D hard. I have 2 of those subs, one of each MRD-M501. I have these amps tuned to give off the most bass they can give. They may not have alot of power for their price but when tuned right, they hit hard. They are wired to do 4 ohms @ 275 watts RMS. For the price of these amps and what they have, it's well worth the money. And don't forget, they are Digital which boosts the price up too.

    The features are Great! The sound is great. The power is very good; it slams my 10" Aluminum Eclipse, but competitors have more power in the price range.

    This is the best amp. The only reason these other people are complaining is because they do not know what they are doing settings wise.
