[QUOTE="bigmizzle99, post: 8279439, member: 660298"] 12 AWG or 14 AWG is fine. 14 AWG will be cheaper if you're pinching pennies. The subs are pick 'em, both quality products. Here is where I think you've run aground...3200W. Even if you could get rated power from Hifonics, lets do the math. 3200W at what efficiency? Lets say 80%. Means you 'll need 4000W out of your electrical to get 3200W. 4000W / 12.8v (generous here) = 312.5 Amps just for sub amp at rated power. How many amps is your stock alt? Maybe 100 Amps? And most of that is used already for other car accessories, say 60 Amps. That means you are 252.5 Amps short, plus still need to power the other amp. You'll be able to get some of that with extra batteries (plural) but you wont ever get near what you need with stock alt and only 1 battery. Stock alt is probably good for up to 1000W. Beyond that, you need to upgrade. [/QUOTE]
