I have all zero gauge wiring, a 110 amp alternator and a kenetic khc 2000 up front.. I plan on adding a second battery and doing the big 3 soon but these XXX's need more powah first, I've been shopping around for used amps and I've found a Memphis mojo 4k for $550 used I was thinking about buying that or buying another hifonics Brz 2400.1 and strapping them, I can't find much info on the Memphis so I figured I'd post this topic, what would be the smarter choice?

you already said the Xxx's need more power with what you have, so why would you be ok with buying a 4k+ amp and run it daily with it "turned down"... you wont like that, and you will want to turn it up....then poof goes your system cause of your bad electrical. lol

stock electrical is good for about 1000wrms with Big 3 done. why get a big amp if you gonna limit it? Get supporting electrical and set your gains properly is my advice.

Think of it this way...your xxx's need more power - the amps is part of that equation. To get more power to your subs you have to have power to feed the amps before you have amps that can amplify the musical signal.

big power = big alt(s) + big cable + big batt(s) + big amp

If you have that amp set up right now with that electrical i am honestly suprised you havent fried your alt or killed your batt... the hifonics suck the power your amp is either set all the way down or your voltage drop is gonna be the death of your system
