I am looking at getting a cap for competitions as my car cannot be running. (street B)

I know caps do not help with dimming lights...you need upgraded battery and alt
, however, if the engine is off is a cap reccomended?....it's a 2000 rms amp

thanks!

With engine off, upgraded alternator won't help. Yellowtop and upgraded stock wires however will help.
I'd run 2gauge - 0gauge ground wire directly to the amp. The car's chassis won't be able to supply the needed current.
The cap can be useful for filtering power spikes.

Thats what the cap is for. Its so you dont drain your battery. It does stop the head lights from dimming.
