Decent Amp For The Price

This is a sleek looking, minimalist looking amp. it will look good anywhere you put it. the plate for covering up the controls and the inputs makes this easy to get a clean looking install. I run this on my Pioneer TS-D680R2's and its a perfect match. brings everything alive. there is some slight doubt that it DOESN'T do rated but unless i clamp it, there's no way to find out. but for the price you can't go wrong. it does get hot, very quickly, just about 20 minutes playing at a higher volume, but so far hasn't gone in to protect. probably has something to do with the less than adequate heat sink. i would buy it again. Sonic Electronix stands behind everything they sell. so you can't really go wrong.
