what im trying to figure out is i have a 1997 "extended cab" lol nissan hardbody p/u. And i am putting 2 12" kicker L7 rated at 1500 watts rms (both together) with a brutus bxi1606d 1600x1 @ 1ohm rms. With a 4 fared power acoustik capacitor. with 2 gauge wire.
What im wonder is will my alternator and battery be okay. with this setup? I absolutely do not want to spend MORE money on another battery OR alternator. if i haft to i will. your opinions PLEASE

It'll be putting a lot of strain on your alternator. That amp can pull about 150 amps(fuses are 80x2). I would at least upgrade your main battery to something like an optima yellow or blue top. The life of your alternator will be greatly reduced, but should live for a while. You will probably notice dimming lights, and the car may stutter right when the bass hits if you don't upgrade the alternator, but other than that you should be ok.

Sell the capacitor. You could have 500,000 farads and none of which will do you ANY good.
By adding more caps and batteries, your alt is forced to charge more electronics, which WILL kill it.
Do this and you'll notice what they say caps are supposed to do:
Do the Big3 Upgrade (power -charge- wire from alt. to batt., ground from batt. to frame, and ground from frame to engine block) all in 4g or bigger wire.
Dimming lights, ground noises, and voltage drop will be things of the past.
Or try this, add the cap and check voltage while system is cranked. Then remove the cap, do the Big3 Upgrade and measure voltage again. The Big3 does what caps are sold for (marketing scam, DON'T waste your money).
Good Luck!

NICE ! I have the same set up ! Look by experience you will DEFINETLY need a Better battery ! I recomend you to get a Kinetik Battery. Or Optima is secondary Option. My alternator gave out after about 10 months after I got my system and they said it was due to my Sound System ! What I did was went to AutoZone and Bought an Alternator with a lifetime warranty so if my sound system messes it up I will replace it for free ! LOL

Ditch the cap. It will only put more stain on your electrical system. Purchase a HO alternator and upgrade the wiring under the hood.
First, go ahead and see if the system works alright w/o any upgrades. Many trucks have beefy alternators as it is. But there's no need for the capacitor - sell it and save yourself some money.

i have went through alot of systems in my truck and have found out that caps are a waste of money and do very little for your sound. I would go to the auto parts store and buy the biggest marine battery you can fit in your vehicals battery tray. you may need to have your alternator rebuilt if it is an older vehical. marine batteries are much better than an optima battery. they try and sell you things you do not need.

i've none a few people with at least 2 L7's and similar setups and never had analternator or battery problems. But if you want 2be completly sure think about eventully purchasing an audio battery and running your amp of them. this will also help you get the max power at yo amp

Here is a guide that will help determine power wire size, correct gain settings and whether or not you need an alternator upgrade:

You'll need Microsoft Excel, a multi-meter (AC volt meter) and a way to burn an audio CD from an MP3.
If you don't have Excel, let me know and I'll send you the required info in an E-mail. sparky3489@yahoo.com
