This enough?

Hey guys, I've got an XS power xp3000 on the way and I'm wondering if it is going to be enough to play my stereo for the day? Amp wise I have a syn 4, a Hifonics 2000 watt Brutus. Also a cadence 2000 watt. I have a pro sport onboard charger. My cranking battery runs through the perko switch but does NOT charge off the alt. I'd like to change this but don't know exactly how. We play the stereos retry hard when wakeboarding as well. Thanks!
