Little advice needed Im planning on running a second battery in the cab of my truck 99 f150 v8 100amp altanater with big 3 done zero gage all around! The amp is a kicker zx2500 pushing 2 15 l7 in a 12 cube box! The amp is brand new hasn't been hooked up yet due to me not having my second battery yet! WHAT BATTERY DO I WANT AS A SECONDARY? HELP!! Was about to pick up a hc2400 kinetik today but was wondering is there somthing better for the money? Should I be looking at a different battery!
