2013 EZGO 48V sound system help

I have installed a fair share of stereo systems in trucks, but I don't have the knowledge wen it comes to electric golf carts. I have a 2013 EZGO 48v (6 8V batteries) that i want to install a decent sounding audio system on. I've been reading about using a stand alone battery but I'm curious how i would tie this in and keep it charged as well. Would that 12V battery be enough to handle multiple accessories? After i figure out how to charge the stand alone battery, I believe I will be good to go

Anyone have pictures of the best location to install a sub-woofer on the EZGO??

Any information will be greatly appreciated. Posting on a forum is a first for me do be easy!

thanks--:thumbup:
