need help on how to power my stereo equipment

[matador_de_sa 10+ year member]

Okay, so I have 2 600W subs, and 4 70W door speakers. I have already done the big 3 upgrade. I know that I will need to upgrade the alternator (65 amps just won't cut it...), I have a '98 subaru legacy outback and I can't seem to find any HOalts out there that fit my car. I am going to have 1480W draw on my electrical system, so at 14 volts that's 105 amps. I assume that I could fairly safely get a 150 amp alternator, too bad I can't find any for my car //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif, if someone could help me find one that would be awesome. Also, I assume I would need to upgrade my battery, but would I also need to get a second battery, and what battery(ies) should I get?

Find a local alternator shop and see what they can do with your alt. I always just take the biggest caseing I can fit in my stock location from a junk yard and get a alt shop to rebuild it with the biggest stator they can get into it and upgrade the voltage regulator.
