obviously the BEST option is to run a second 12v battery in the back of my car for my system. however he said whether i do that or not i should still remove my capacitor. he said they are shi.t. for one he says they actually take away power from your system, 2 they can destroy alternators and batteries, and i should just remove the capacitor all together and either A) deal with the headlight dimming some, or B) up my alternator and get a 2nd battery. is this true that capacitors are bad?
