This 180 amp unit could be overkill although the price doesn't seem too bad. Maybe figure out what the peak wattage of your system might be, after converting watts to amps and summing up all the RMS ratings of your amps as a starting point. Come up with a factor for your likely peak sound system wattage and compare it to that 105 amps. I found that the stock 105 amp unit was enough most of the time when I had a system. The lights hardly dimmed at all except for extremely bass heavy music. As for capacitors, I've always thought they were a waste of money, especially the ones especially designed for car audio (there are other general purpose units available much cheaper that can be used together)

 

Go to O'Reilly's and get the Delfi 105-110 amp alternator. As for a capacitor, they are good for current ballance. A CAP can keep the current flow level so as not to undervolt the ecu.

 

alterstart is a great company with excellent customer service, i blew out a 180 amp alt. and they replaced it no questions asked.

 

how many amps are our cars to begin with... 110 i think.

 

I got mine from him, and like hobo said they have excellent customer service.. i bought a wrong part, but they exchange it for free
