You get what you pay for.. just keep that in mind when looking for an amp. I say get something that is "too powerful" and run it turned down as instead of running something too little or just enough turned all the way up. Go to local dealers and hear stuff before you buy, test it out to get a feel for how it works, just keep in mind it will sound different in your car. Good luck man.
