Default Options to stop lighta dimming

I have a 03 legacy L. My alternator isn't strong enough to power my Sound system. I have a couple options to help but I'm not sure what to do and what order so I can fix the problem while spending the least amount of money. 1.Big 3 2.HID lights 3.Swapping a alternator with a newer or larger sized on from a wrx or legacy gt 4.New alternator I'm running a 12" sub with a 1000 watt amp (Sony xplod) and 2 kickers components with a 500 watt (lightning audio) I also have a 1.5k cap. Could another option be buying a new 4 channel amp instead of running to separate amps?

swapping to a larger alternator is going to be the "easiest" fix for everything

Could I swap a newer or more powerful one from a more advanced model?

Big 3 first, for sure. That's the cheapest way to try to take care of some light dimming.

After doing that in my old truck I was able to run two 700w mono amps and a 4-channel with proper wiring with nearly no light dimming. A single 12" sub and Sony amp shouldn't require too crazy of modifications

Big 3, better/bigger battery (what kind of bat do you have?), bigger alternator.

I would do it in that order, you shouldn't really be drawing to much with that setup.

I have a yellowtop optima. And I believe my alternator puts out at about 70 which is pretty low. But big 3 will be my next move.

Get a bigger stronger battery and a capacitor.
