The alt should always be the first thing that is done when upgrading your electrical. The reason being is the large agm car audio batteries that we use stress stock alternators to the point of failure. The reason is because they require such a high rate of amperage to recharge over a standard lead acid battery and it puts quite a bit of extra strain on the alt.

Another reason why the alt should come first is because extra capacity from a battery is limited by how much the alt is able to charge. If your stock is 90 amps and your amp is pulling 150 you have already exceeded your alts capability and are beginning to drain your battery. With a 250 amp alt you would have the juice to throw 150 amps at the amplifier, run the accessories in the car, and have leftover amperage to charge the stock battery. This puts less strain on the battery while the alt does the job it is supposed to.

Of course the big 3 is technically the first thing that should be done before a battery or an alt.

Go with the alt first and thank me later!

First the alt, 90 A is tiny for the car electrical +1300 watt. If you get a 250 amp alt you can back up your system complete with the alt.

If you have a lead acid batt and lookin for a quality nicepriced AGM batt http://www.stevemeadedesigns.com/board/topic/144556-dont-seem-like-a-bad-deal/#entry2285159 here.

from personal experience I say battery. I got alt first and amp was still going into protect. I put battery in and no more protect. Then I fry alt on accident and only have battery, and I don't have any issues with protect.

running stock 90a alt now and only ~750wrms :(

I guess no one looked at the thread I posted. Ed knows what he's talking about.

Didn't read all post lazy today. Me if battery is reading 12 volts. I would get alternator first with 3 three at same time. Only run system with engine running . Then save up for batterys. Don't forget you will want some zero wire to. When you play hard you pay hard that's just how it is in car audio. I where I 'm from time over time.
