I saw the name tc300 and recognized it from the bad info I've read on the caraudio forums he mentioned lol. Capacitors are useful but only to an extent. The correct way is to beef up your wiring to handle the extra load on the car's electrical system. The capacitor is like stated earlier a band aid to the problem. I don't run them by personal choice but I do understand their benefits. But knocking someone for wanting to run one is just plain retarded and makes you look like a douche bag. But as mentioned earlier the big 3 will be your best benefit to do. It'll help your entire electrical system.
