It certainly isn't the loudest amp, but it does the job and sounds nice and clear. If your car is quiet, this will probably be enough to drive 4 speakers just fine. If you have a loud car (ie, loud exhaust), this may not be enough.

This is a great amp. Crystal clear! Not the loudest amp. Nor does it have huge bass. But it still makes my infinity references kick pretty hard. I'm running a 2 ohm system and for this amp, that is definitely the way to go.
