Head Unit=Alpine or Pioneer Amp=MMATS Baby D or Full D
It really depends on what kind of music you listen to. If you like Bass or loud thumps, get a MMATT's full D amp with either a 12" or 15" Juggernaut and use MB Quart's for the Mids and Highs. You can fit a MB Quart 6x9 in the back and the 6.5" with tweeters in the front. You can have a box made to put over where the gas tank is. If you like rock or other kinds of crisp music, try the JL Audio sub with a MMATT's Baby D. Use the same MB Quarts all around. They are truely the best speakers on the market.
