sky high

So I'm still waiting for my 310A alternator from Singer. I also ordered a 50 feet 2/0 Sky High cable along with some 2/0 terminals. Next is to do buy an amp, extra batteries, subs, ohh and extra wires. My plan is Sundown two* 12 Zv3 but I've seen the 12 Zv4s and I love them. Planning on...
