your memphis mojo 12 rms is WAY under rated. That is one hell of a sub. I have
pr 10's with 200 rms that hit harder than alot of 12's around here. and thats their lowest sub! the mojos require a performance alternator and all kinds of ****. I swear by memphis and its the only thing that I'll put in my truck. give 'em some credit.
I know with all that info its probably hard to keep everything straight so good effort
