That one I can't answer for you. In my Legacy, I used a 90 amp STI alternator and it bolted in. Retail on that alt was 5 or 6 bills as I recall, so you probably want to stay with the Maxima alt if at all possible. Perhaps somebody on the board has put that alt on a 2.2.

If you have the wire already, go for the 4 gauge. Although, the 6 will probably be plenty big.

You probably won't need a cap if you do a 90 or 100 amp alternator with nice fat wires. I would start with just the alt and if the bass still seems a bit soft, go for the cap.

Another helpful upgrade is a voltmeter gauge. It'll allow you to see what effect different electronics have on your electrical system. And you can spot problems before they leave you stranded.

Two possible solutions. First, you could add a stiffening capacitor. It'll help if you're just going over on the big bass hits. But if your overall draw is more than the cars electrical system puts out, you'll find your battery going dead even while you're driving down the freeway.

The other fix is to upgrade your alternator. With 600 watts, if there's nothing else drawing big in the system, a 90 or 100 amp alternator should fix you nicely. Don't overlook the wires. You'll want to do a 'big three' upgrade. That's your supply wire from alt to batt, ground from batt to engine, and ground from engine to chassis.

Also, check the amp for heat. As it gets hotter, it will lose efficiency and you'll turn your stereo up higher to get the same output. Same with the woofers, but a ported box won't likely fit very well in your Brat.

Forgot to give you my info. I can be EMailed at nmatern@gmail.com or text or call me at 801.842.1504. I'll be out and about most of the day and into the evening today, so if you're in a hurry for the money, the phone would probably be fastest.

So, I'm going to need your Paypal info and we should discuss logistics. I'm hoping my friend will be able to pick up the parts sometime near the weekend, but it's not definite. So I'm posting an ad on uship.com and I'll need an address or cross streets somewhat near where you would be willing to meet a third party who'll be picking up the parts.

Thanks,

Nick
