Jeremy is correct in stating that the amp is rated at 5 watts X 4 channels. I run 2 of these in my car. 1 of them is in 4 channel mode to my tweets and mids, the other is bridged to my midbass drivers. All I can say is WOW!!!!!!!!!!!!!!!!!!!! These amps will hold their own against any "SQ amp" on the market without a doubt in my mind.
