Enough Power?

[Ruler]

hey all

i am looking to run a new system in my 98 subaru liberty/legacy, and need to think about what eletricle upgrades i need.

im going to be running:

subs. 2 dd1515's or 2 dd2515's

sub amp. dd1mb 1200 rms 1ohm

component amp. boss audio "1500" watt 4-channel amp(pretty shit amp more likely 75 rms a channel)

to upgrade electrical, im going to do the "big 3", add another good battery and am not sure what else im going to need to have enough power.

1. do i need to upgrade an alternator, i would really not wanna do this yet.?

2. would i need more then 1 battery in addition to the stock front one.?

3. is there anything im missing here?

thanks for your help..

add a second small battery in the rear and you will be fine for just daily driving around beating. also the boss amp is prolly like 30rms per chan
