[QUOTE="zane, post: 94527, member: 540617"] What type of vehicle and exactly how many amps is your alternator rated at? Current fluxuations are pretty common throughout a car- so lets start with that. I would not reccomend adding the second battery- just another load on the cars electrical system. (The alternator will have to charge it now too in addition to the other battery.) Omit the cap from the system. They are worthless. A burst of power for a fraction of a second provides no benefit to a struggling charging system. Have a look here if you are in doubt: [URL="http://forums.caraudio.com/vb/showthread.php?threadid=15196"]http://forums.caraudio.com/vb/showthread.php?threadid=15196[/URL] A typical charging system will produce roughly 14.4 VDC at idle. You can check this at your battery with a DVM while the car is running. Also- have you upgraded the main posative wire that goes from your alternator to your battery yet? It should be the same gauge as your main power wire to your system if possible. take it easy, -zane [/QUOTE]
