Had this installed for my car and have no regrets whatsoever, the Amp is 300 RMS CEA Rated and the power Birth Sheet shows 360+ RMS.
Sound quality is top notch for the price its awesome Value for Money. It can easily push one Scosche HD1204 sub and a pair of speakers real good. Nice for an Entry level Setup +++
