how do i add a second battery without blowing something up. i think i'm supposed to connect positive to positive and neg to neg (parallel), rather than series, am i correct?csuho said:if ur gettin dimming either upgrade ur alt or add an extra battery or upgrade the battery under the hood and do the big 3.
Not true.phathom said:first off you shouldn't be running a 1000W+ system without a upgraded charging system, but it basically works more efficient than a battery as it charges and discharges faster, haven't tried a batcap myself, but I've heard they are good, currently I've got Optima yellow top 2 1 farad rockford capacitors (make sure you get good capaciters like rockford, phoenixgold, monster as cheap capacitors aren't a true farad and are more like a half the capitance that they're rated for.) big 3 done, and new 4 guage running thru the entire system. The capaciters basically act as a buffer between the amp and normal bat-alt connections, they do make the bass hit a little harder and stop dimming as it's pulling power from them first before the bat and alt so they can save your alternator if you haven't upgraded it yet like I haven't, but my reccomendation for a true 1000W setup (not like wannabe brands claiming 1000s everywhere for cheap) would be a hoa and deep cycle battery, big 3 minimum. hoa, big 3, optima yellow top, one cap would be optimal. if you got the money for it and are serious about it, go all out for quality, they're not so much as a bandaid (although some people use it like that), as they are a part of a bigger more efficient and stable electrical system for your sound system.
