Your are not gonna get much at that price, but here is a Profile 500 rms @2 ohms monoblock amp for $113...thats about as good as you're gonna get...im assuming you have the dual 4 ohm L5
And the 10 is 450 watts rms if im not mistaken....and this amp is 500 rms so Profile is one of the best budget amps and crunch as well
