Planet Audio amps aren't bad. They're fairly underrated with the power they put out and they sound decent. However, U.S. Acoustic amplifiers are in my opinion just as good or maybe even better than planet audio amps. U.S. Acoustics underrates their amps and the power specs they are rated at is 12.9volts. They put out very clean power and they are very reasonably priced. Plus, they are engineered in the USA and come with a 3 year warranty if purchased through an authorized dealer. I'd say U.S. Acoustics is as good as Mtx or Kicker w/o the high price. Check 'em out at
