Re: power problems !! :(

upgrade the big 3 first to 4ga or bigger (add them to the stock wire, don't replace it, more wire is better)
alt + to batt +
batt - to ground
engine to ground

That should REALLY help, if not kill your dimming issues. If you still have problems then you can go for a new battery if your stock one is old or bad, or you could get a HO alternator if you want.

caps work for some cars and not for others, sugeest you TRY it first - before shelling out $100+ for one

the real problem is that the load on the cars electrical system by a large amp is not straight DC, it's pulsed DC - more like an AC wave, so the impedance of the wire (in this case the iductive reactance). This is so because the power input is controlled by a pusle with modulation circuit.
