A:AnswerWhen designing a car stereo the very first thing you need to do before anything else is have some sort of a budget at hand, then you can start planing accordingly. There's to many options available to tell you what the ideal speaker would be. The differences in quality are vast as well as cost. That's why you budget is the ideal starting point.
A:AnswerNot enough power. Pioneer amps are overrated. Personally I'd go with Skar. Same price range but double the power. Skar rp1500.1d is a 1500 watt amp for 170 bucks. Bench test it was putting out over 2300 watts.
