Rayven, it sounds like you're looking to build a car audio system. Most of this board is dedicated to home audio, so I'm not sure how much real help you'll find here - the two scenes do cross over, but not that often. Are you looking just for amplifiers for speakers you already have, or are you looking to buy both speakers and the matching amps? What is your ultimate goal with the system? Overall sound quality? High-end competition sound? Something loud to impress the crew? Bass to wake the dead, and enough mids so it still sounds like there's music? Also, what kind of vehicle (i.e. a smaller car or a big SUV)? Oh, and of course budget is always a consideration. We don't want to suggest something that costs your entire budget for a single speaker.
Focal Audio makes nice products for both home and auto, and they have the advantage of producing their own drivers. They're known for being very accurate in sound reproduction, and work well in sound quality competition auto rigs, but might not be the last word in bold and loud. They also tend to be on the more expensive end.
