Ok I recently purchased my first set of components, JL VR650CSi, I need to get the other set for the rear deck. I am also going to purchase the Alpine 9830 HU, a 4 channel JL amp for the interior components, a JLW3v2 and an amp to power the sub.
My question is with running to amps I'm gonna change out my battery to an Optima yellow top, Will I need a Capacitor?
What does it do? In what cases will I need one?
The amp I'm gonna get for the interior is the JL 300/4 but I'm not sure what amp I'm gonna get to run the W3.

Oh yeah how much does the Optima Yellow Top Battery cost?

Thanks
Ryan

 

It's all about the wiring.

I have :
- Pioneer 6.5" Motorized TV/DVD
- Pioneer DVD Navigation
- Pioneer XM Satellite Radio
- Eclipse 6.5" Components
- Pioneer 6.5" 3-Way Speakers
- Pioneer 12" Subwoofer (2x)
- Eclipse DA7232 2000 Watt Amplifier
- Eclipse PA5422 800 Watt Amplifier

No cap and an Exide battery. I have 0 ga wiring from the battery back to the distribution block and 4 ga from the distribution block back to the amps.

I can run my HID's at night and blast my system and have not had any dimming issues.
