Question

Do I need a capacitor for a 1000w system?

Answer 1

No.

A capacitor is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing else. If the current isn't there, a cap won't help.

The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.

Check these sites out...it is a good reference.

If your headlight dims with the bass notes, the “BIG 3” might work.  If not an H.O. alternator will be needed, or else be prepared to pour a lot of $$$ for batteries.
