thats the farad rating.
Most caps are 1 farad. The higher the capacitance, the more energy it can store.
I read somewhere that 1 farad per 500WRMS is ideal.

i dont think u will find a 4 farad cap.
For a setup like that, i think you'd be better off getting an Optima yellow top in the boot and a split charging system.

what amps are you gonna use, you can get caps at some silly ratings, like 300farad or something stupid

Quick note, large capacitances are often hard to come by. Using two smaller ones in parallel (the values simply add) will give you a large distributed capacitance with half the ESR of a larger cap.
Stuart
P.S. ESR is equivalent series resistance. the lower, the better.

xhale, shut up. The vibe VP4 is a good amp. It did have a problem before where the centre of the circuit board would crack, but it was sorted.

ummm a 2000RMS amp a 0 ohms????
Ur gonna need 2000RMS at 2 ohms, eek!
How much fekin money u got? Ur gonna need to sound deaden ur car, split charging system ect ect

with 2000RMS of power, to get the most from it ur gonna need.
1.Uprated Alternater.
2.Upgrade the big 3.
3.Split charge system.
4.Optima yellow top/Exide 900DC
5.Power cap to smooth it all out.

ok bad idea ill just stick to 2 vp4's. what about 2 2farad capacitors to run them
