yer i got a basic understanding in the cooncept of capacitors.. dont really need one atm (dont have subs lol its my speakers bass that dims the ligths, its fukd i know)...

but i did the research and its pretty basic concept to wire up the second battery. basically there is a device (think they call it a "relay")that allows current from the secondary battery to only flow one way. if the second battery goes flat it will therefore not draw power from the primary and will only be charged by the alternator.

so now what i have to do is take my car apart and rewire all the power, which is good as the (insert word) from wow sight and sound thought it would be clever to throw the power cords beside the signal cords and give me some lovely distortion!!! but il save that for another thread lol
