The second day I had my truck I put in http://shopping.yahoo.com/p:Kenwood%...JKdQDqJqAph74F a kenwood with all around Alphine 2 way speakers. I have a 800 watt amp going to the speakers, then I have a 1200 watt amp going to the 12" sub. I can crank all the way up and it is cristel clear. The kenwood model gives you so many choices in where you want the sound levels. The whole system cost me around $500 bucks
