Pics of my new setup....

You can get the same results from upgrading the underhood wiring with some 4g or 1/0 "big 3"....looks like you already have the - battery to chassis done.
Not trying to down on your set-up at all, man.

I thought about doing the big 3, but Im not having any problem as of now, so I might wait on that for a few.

And as far as the cap goes, do not get rid of it! That would be stupid! Now you do not necessarily have to run it, but when the speaker asks for juice, and they need it now...sometmes it robs from the other componets in the car...headlights mostly! So you go down the road blinkin without the cap! It does not necessarily stop the fading totally, but it really helps. You could run more batteries though. And you spent thousands on that system, but you forgot the most IMPORTANT part...THE OPTIMA BATTERIES!!!!One red under the hood, and a yellow out back.....thats my recomendation. But at least run one more if you already arent. Also that post about having to charge the cap...one its full its no biggie on the alternator. cause then the alternator then has to just fill up what has been used....Also what is the biggest speakers I can run in my 02 without obstructing my rear window?
***i would guess you spent around 5 large***

Price? How about just over 1/5 of what you think
Just gotta know how to shop for stuff 
The speakers are 12s. The box I got from subthump. They make a really nice product. It comes out to about 1 cu. ft. per side. Im not going to take the cap out. It looks cool too. I plan on getting a yellow top, just havent made it to the store yet to get one with this damn flu bug.

Upgrading the Big 3, is a very good idea. The lower the voltage drop accross the power path, the better. But a BFC (Big Freaking Capacitor) is still helpful when driving a high powered sub amplifier.
WOW THAT IS NICE!!!! I wont be surprised when you get JACKED and come back later feeling like **** that you got ROBBED!!
GOOD LUCK!!!
REALLY NICE SET UP, I bet it sounds BAD ***!

The capacitor in this case acts like a buffer. With sufficient capacitance you should never see the voltage dip and rise at the batt/alt. This assumes you have a sufficient current supply from the alternator to run the entire electrical system.

As far as a second battery goes, you will want to stay away from that idea until you upgrade you alternator, which it doesnt sound like you need to do. I would recommend upgrading the underhood wiring though for any vehicle that is having more strain on its electrical system than the manufacturer intended.

Wickedwarlock, where are you getting the 275amp alternator. Will it fit or match against the 2002 z28 electronic system? I need to upgrade my alternator also - I'm running diamond separates in the front and mids, 10" JLw3 in the back, memphis amp to push the front and kenwood to push the sub. Running 800 watts rms and 1600 peak. My lights dim when I pound it. The stock alternator cannot handle even with the yellow top optima.

The prices are $449.00 for a 275amp, $399.00 for a 250amp and $349.00 for a 200 amp alternator.
They have a 200 amp alternator for $250 on ebay, best deal unless you need more power.

I need to get one, but the thing I dont like about the HO alternators is that they dont have a warrenty, only on labor and such. So, if it craps out in a month, youre screwed and have to buy another one
My autozone has a lifetime replacement. I found out that I now have to the big 3 upgrade though

Edit: Here's the 200amp on ebay that's a great deal.

Like I said, they make a 275amp also.

If your going to change them, get two yellow tops, not one red and one yellow. The yellow ones are deep cycle batteries, the red one is not.
And the alternator will be the best upgrade. The biggest I could find is 275amp, it does 135amps at idle.
$449 plus shipping and the $25 for the extra 4 guage wire to the battery.
15" inch woofers fit fine.
