will i need a alternator

[Sone]

i have a 105 amp alternator.

will be running 2 500/1 jl amps and a 300/4 jl amp

I plan on getting a yellow top and I already own 1 cap....should I upgrade or will I be fine?

hook everything up and see. it wouldn't hurt to get a new alt. i run a rf 1001bd and a us acoustics 4065 and my old 100 amp factory alt. struggled at times. you could try upgrading the big 3 and if that doesn't work you would have the upgrade done for a new alt. here's a good place to see how to do the big 3: http://forum.sounddomain.com/ubb/ult...c;f=5;t=007801
