Bass control and sound quality was a big concern of mine and this would land in my top 5. Review: I have purchased 2 of these amps, the first time was definitely my fault the speaker wires touched and dead shorted, not complaining about that situation. Although the 2nd amp I got threw itself into protect out of nowhere , I crunk up my vehicle and the amp was in protect , everting was just fine the night before. I don’t believe this is a true sundown amp… sundown does not offer this amp on their website , the biggest SFB series amp they offer is a 1800. ## Features - Features: Monoblock Class D Amplifier.
