Im going to be putting 2 15"s in my 67 mustang behind the rear seat, i was wondering if the stock alternator would be able to handle the amps if 2 2000 watt amps, if i should get a cap or a new alternator all together. ive been told that for safety reasons i should have a cap, but others said its worth it to pay the 200bucks for a bigger alternator. just hoping someone could help me before i have to start experimenting.

a stock alternator(60 amp) will not handle it,you will drain the batteries and the aternator will over work to compensate.I got a chevy 1 wire 100 amp for about 90 bucks from a rebuild place and polished the case.Your better off running 2 batteries.A cap really doesnt work,but they look cool with the flashing display,i have been through the cap thing from 1 farad to 5 farad and had better luck with 2 strong NEW batteries,dont add a new battery to your current one,it will kill it.

a guess an isolator would be the correct term

i was planning just to use that and put an optima yellow top in the back.

yeah,that will work,but i feel its a waste of money. I dont use those in anything I own,bit you really want to use one,just buy a 3 terminal HD type,it will do the same thing and cost about 15 bucks.100MilesNRunnin said:
We just took my boat out and played the stereo for hours on end and never killed the battery.It has dual marine batteries,2 15" CV woofers,4 Pioneer 6X9"s and 4 Pionner 6.5".The amps total about 4000 watts and its played loud for hours.The batteries are wired together in parallel.I have my truck wired the same way with 3 JL 12W6's and about 3200 watts,but I added a blue top Orbit to the 2 year old red top Optima,The red top wasted the blur top because it was older.
