1 ohm dcr for a daily driver in a WRX Sedan?

Sounds like that might be pushing it. I know subarus only come with 90 amp alternators but you won't know how it will work untill you try it. Go ahead and try the amp on stock electrical it may wor it may not. If not there is always dc power

That's pusing it... a lot

You're giving us no information either..

Do you have the big 3, aftermarket batter, HO alt?

THese are all things we need to know..

100% Stock? It won't work.

Do the big3 in 0 gauge. Add a second batt, like an xs or ...optima, and check your voltage.

It may work, it may not !

After that, H O alt!

Will need Big 3 in 1/0 and get with Nathan at XS and tell him your plans to see what batt will work the best for your car!

High Output alternator and a small XS Power batt under the hood.

It takes power to make power.

I know Big 3 and 0 gauge are a must.

Dont know about HO alt and aftermarket battery. Most likely an aftermarket WILL BE necessary since its a sedan.

If you do not get more batteries and/or big 3 and/or h.o alternator your car will asplode :x

We're talking about a power hungry SAZ-2500D.... there is no maybe, he will need electrical upgrades.
