Off The Chain

This amp is phenomenal!! I have it connected to my Kenwood Excelon X996 (which is also a phenom head unit) and it kicks out the sound like no other amp I've used before!! I had a Fosgat Punch 4 channel w/450 watts but it doesn't compare to my new Crunch. It is a really good amp for the price and you will not be disappointed with the quality of the product and especially the sound!!

Great little amp!

For the price this is a very nice little amplifier for mids and/or highs! Has a high pass filter thats to die for if youre doing highs. A little tougher to pin point frequency unless you have a DD-1 but very nice. Doesnt quite put out rated power but its close enough. Clamped it at ~65W RMS at 2 ohms per channel running at 14.4 steady. I would definitely recommend this amp to someone looking to power their door speakers nicely. Gets a little warm but never overheats.
