Depends on how much power you're putting to em, if you buy high quality speakers like mid range MB Quart, Infinity, Boston Acoustics, Eclipse, Clarion, etc... then buy em a decent amp to make em sound clean and nice... Personally I have Eclipse 6.5" 2ways (~$200) up front and some mid range Kenwoods($140 but aren't near the Eclipse sound quality - I only bought em cuz they are in back and I got a deal) MTX makes nice, value packed amps... PM me if you want more info on audio stuff. I've had everything from 3 amps, 2 15", and 6 mid and high speaks to more mild setups... Glad to help.. Whatever you do, install it yourself its not that hard and once you learn you'll retain that knowledge for life - save the money and buy better equipment or go faster
