that i cant tell you.
im doing the research and upgrading when mine blows, and upgrading the sub as well since those are no better. JLaudio makes some direct fits for the sub, but i dont know about the amp.
if you blow the amp and upgrade it, youll blow the sub. if you blow the sub and upgrade it, youll blow the amp. and if you blew either and just replace it, its just a matter of time till it blows again. do yourself a favor and drop like 150 to upgrade both while you have the rack out.
