I purchased this amp a couple years ago and it is very clean. It puts out pretty decent power especially at 1 ohm and it's still stable! I have pushed it pretty hard and have never heard any clipping nor has it ever gone into protect mode. I had someone offer me almost double what I paid for this amp new and I refused to sell it.

I recommend highly this product.
WHY???
1: It is 1 ohm stable ( you can run a total of 4-4 ohm loads wired in parallel. ie. *two DVC subwoofers where as each voice coil rated at 4 ohms, resulting in a 1 ohm load*),
2: The power it puts out is really close/spot on to what the manufacture claims.
3: Its sizes lets you install it in more creative and smaller spaces,
4: Bass boost remote!!!
5: Good signal to noise ratio for a monoblock at this price!
6: THE PRICE!!!

Now for my install. \
The amp is on Kicker 8 gauge power and ground wires and powering two eight inch dvc (each voice coil is rated at 4 ohms) kicker subwoofers wired down to 1ohm. The subs are rated at 200 watts RMS each, so it is a perfect match. This amplifier easily pushes them to their limits and barely gets warm. Now these subs I have owned for over a month and were already broken in upon the use of this amp so I just swapped amps and juiced it up. I just purchased this amplifier so I cannot comment on its durability so I will automatically rate that part a 5.
BTW... The speakers outputs are still large enough to accommodate two sets of good sized speaker wire.

HOPE THIS WAS HELPFUL

I am using this amp to run a 12" subwoofer. I am very pleased with the features this amp has such as a vaiable subsonic filter and low pass 24 dB crossover. It's also stable to 1 Ohm. Another great MB Quart product. I would recommend this amp.

I bought this amp to match my MB Quart RLP 254 10" subs and I can say I am very satisfied with how they push my 10's. I have them wired at 1ohm (where else are you going to get a quality 1ohm stable amp at this price?) and have ran them for hours with no problems. I love the remote bass knob and the fact the power ratings complimented my 10's perfectly without overpowering them.
