I'm running 2 500/1 JL amps to two 12w6v2 subs, and an Infinity 550 watt amp to power the speakers and head-unit.

One should be fine. I ran 2 1000/1s and a 300/4 with a HC2000 but stock 140amp.

Whats your stock alt rated at? The batteries can only be filled by how much juice is put into them, but 2 batteries would help for spurts of hard hitting bass.

according to this source: http://www.autosite.com/content/research/vir/index.cfm/vehicle_number_int/1018302/Action/StadardEquipment

your vehicle has an 90A alternator. i also recommend upgrading the big-3 as well.

newest I could come up with is '05 - 90A

IMO - at best, you'll be pushing it

So should i upgrade my alt? Where can I get a better one at?

 

[audiolife 5,000+ posts]

call and ask. generally speaking if anything with the alt has changed over the years from subaru it takes 3 years for the after market to catch up...

 

[gl4662 10+ year member]

Oh, so for now I should just stick with my stock alt?
