Nah to be honest it is a half decent amp, unless your looking for tons of power Id keep with it. However maybe some different subs in a ported box, would help a lot id imagine. Something in the 1000rms range per sub. Or some under rated 800rms subs.
oh alrighti had 2 15 l7s but i sold them and got these for 60 dollars off of a friend and these hit way harder idkk im just trying to find good speakers to buy and amps
