Well are they?

I noticed after I got my system back up to par, that every illuminated device in the cabin dims substantially every time the bass hits, so I need a cap.. What is a good size cap to get? I dont want to get anything more that what I need.. any benefit to digital readout vs. standard cap?

considering cost, I say no. But it will let you see what voltage your electrical system is operating at.

Anyway, general rule of thumb is 1 farad per 1000 watts. There may be a bit of charge/discharge time difference between brands, but I don't know for certain.

Before you add a capacitor though, there is a MUCH cheaper thing to try. Upgrade the three "magic" wires.

1. Altenator to battery +
2. Engine to chassis
3. Chassis to battery -

Use 4 guage wire on that, if you're still having problems with dimming, consider a cap and/or upgrade your altenator.
