This is short and simple. Do not get these amps. My shop sells them, and weve had 4 come back, and the others sound like poop. I tested for RMS power, and on the 1000 watt one, i wasnt even getting 600. Ive tried multiple amps of this series, in a few different installs, and they sound terrible and are very very weak. We plug up other amps and instantly its 100 times better in all areas. Avoid these amps at all costs.
