New Alternator or Battery?

[MikeyF 10+ year member]

Alright, so, i've always been on stock electrical, and am looking to finally upgrade. I am going to run about 1300rms sub wise, about 100rms comp wise, and have a stock 100amp alternator. I get decent voltage drops off of 600rms right now. I was going to drop around $150 on a battery. I looked on eGay and saw a 200amp high output alternator for $200 from DBelectrical. I don't know too much about alternators, but I am pretty sure it didn't state it's idle amps, etc. So, my question would be, would it be worth upgrading my alternator to that, or getting a battery. Any help would be greatly appreciated, thanks.

Don't need to upgrade your alt unless you go over 2-3k rms.

A second batt in the back should take care of your voltage drop. But also make sure you get your starting batt tested in case its going bad.

Go with a better batt under the hood and one in the back and do the big 3

Thanks for the tips. Haven't done the Big 3 yet, soon to be done within two weeks. To the poster above me. All I was asking was if it was worth upgrading the alternator while I had the money. I do search, and check for the results.

alty upgrades are nice to have. i'd start with a yellow top for a kinetik up front. you can likely find these cheap on craigstlist. if you wanna spend the extra $ and get nice bats go with XS (previous powermaster).

an ho alty for 200 isnt bad at all, considering most name brand ones are 400+ at least
