you never need a capacitor.
if your lights are dimming, replace the "big 3" for wiring
if they still dim, look at a larger alternator and a yellow top battery

the system shuts off due to thermal protection mode on the amplifiers being triggered by the amps clipping.
amplifiers are clipping due to lack of sufficient current and voltage rails sagging.
fix would be a larger alternator, or lower volume.
