Try Searching
For audio go Yellow top Optima, and find an alternator with higher output.... there are shops out there that will take your exsisting one and up it but thats on how much money you have and what youre after.

I got my new alternator from ohio generator. 180 amp vs 105 amp oem. Got it for $400. They have a website with a contact number. I would give it to you, but i'm too lazy to get outta my recliner right now. Give them a call and they will set you up. The service was excellent with fast shipping.

Plus you get a rad sticker for your ride. Or toolbox. Or trapper keeper if your of school age.
