small electrical problem.
when my music is on the dash lights and headlights dim in time with the sub booming. im not talking only when its at full whack, even at half volume.
its a 1200W sub and the battery is a standard Vx one.
im planning a HID install this week so im worried it may finally push the batteries/alternators limits over the edge.
so my question is, how do i stop this, do i need to install one of these capacitor thingies, i hear people talking about "the big three" would this solve it, if so, what exactly does "the big three" entail?
cheers for your help.
