Do I need a new battery if I want this setup?

[Chad_Brown80]

Hey guys I think i've decided on what I want to go with as far as a setup. I'm going to go with 2 Kicker L7 15' subs. With a Kicker 1200x1 amp to each sub. SQ isnt really as important as SPL and deep bass for the kind of music I listen to. My question I guess would be what else do I need to get to finish this project up? I'm trying not to have to get a new battery, how effective can a capacitor be? Also does anyone know if this would be easy to connect to a 2002 VW Jetta's Monsoon factory sound system? Alright well you guys have been really helpful in the past and thats why im sure someone can help me figure out what to do. Any help would be much appreciated, thanks guys.

If you upgraded the big 3, I dont think you should need a cap or a second battery.

Here's the easiest (albeit not the cheapest) thing to do: upgrade your alternator. No need for a second battery or that useless capacitor. ;)

I'd say the big 3 is easiest (good start), then cap (although mostly ineffective), then battery (may not be enough), then alternator (last solution, will solve pretty much anything). Just try to big three for now, that should solve your problem, then try a battery. I wouldn't try a alt unless the big three and batt dont do enough.

What exactly is the big 3? And why would you put a cap in before you upgrade the alternator? The cap isn't going to help with power distribution or lighten the load on the electrical system.

The big 3 is the wiring under the hood. When you upgrade the big 3, you usually upgrade your alternator-to-battery, battery-to-ground, and engine block-to-ground wires to 1/0. It reduces resistance in those wires, and makes the electrical system more efficient, and, for most situations, prevents the need for a cap or battery. Check CAF, they could explain it better than I.

I put the cap before the alt because it's easier, not better. Although I should have put big 3 after battery, because that can be pretty hard to do in some vehicles. With 2 1200 watt amps, a bigger alt would probably be the best bet, but he'd still have to upgrade the big 3 to offer the greater power less resistance.
