hey i had 4 12's L7s with an kicker 2500 and let me tell you the wipers will jump hard... if u run it with only two 15's remember to be careful since you'll have an extra 500 rms on them.... good luck
you dont really have extra...those 15's will take all that power easily..//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif if those are dual 4 ohm, u have to wire either to 1 or 8ohms...that amp is only good to 2 ohms...oops on ur part
