This thing is clean! I set up my friends car with and I toned it and man it was clean, bass hit nice, and the mids and highs got clean sound.
First, this amp is listed on the this website as a 4x75.... basic four channel amp. This is however, inccorrect; it is in face a five channel amp; 4x75+200 at 4ohm. I'm currentily running this amp with two JL audio TR650-CSI 6.5" component sets and two JL 10W0-4 subs. An Alpine head unit is running it all. The sound quality is great, I couldn't ask for better, definatily not at this price. The amp is well worth the money. I was hesitant at first to get an amp by some company called autotek that I'd never heard of, but the guy at my local car stereo place had one on hand that someone had ordered then decided they didn't want. He told me if I went with this amp it would save me about $300 and the sound would be top notch. He wasn't kidding! I even now plan on throwing another set of the JL TR650-CSI along with a pair of JL 6W0 subs and I'm going to run those with the Autotek SX-480. I'm very impressed with the overall quality; I've ran my system since July 03 and never had a lick of problems. However, I havn't tried running the amp bridged; I just don't need to fo my application. I would definatily tell someone looking for a good amp to have a serious look at Autotek
This amp came in a used car i bought. I have a set of Infinity Kappa 6.1 6.5" components and a set of Memphis 6x9 in the rear deck along with A Pioneer 12" sub. This amp is enough, plus some to make great sounding music. if you want loud, clear highs and mids along with deep low bass. asuming you hook a reasonable sub to it. then this is the amp for you.
