So help me out here I was always told you need a cap til recently I mentioned to someone they would need a big one for the gear he was gonna run at least a 10 farad I said and reading the post most of you guys left up your saying the same thing i was told they don't recover fast enough to fully charge cuz their too big I was told to get no bigger than a 2 farad but according to some of you guys 1 farad is not that great either so my question is if I used a Drycell deepcycle battery and maybe a bigger gauge wire from the alternator to the starter would that be better even though i always had 2 optimas in my car?

Neither is better, battery's and capacitors store power, alternators MAKE power, if your adding accessories such as amps you need a larger alternator to supply that power. Once you have a good alternator set up you can then get a capacitor to slightly and I mean slighty smooth out the current. And additional battery's are only useful if you are running your stereo with your car off for extended periods.

That makes sense but I do usually run the stereo when the car is off mostly watching movies or playstation, lasts bout 1 1/2 to 2 hours before I need to start the car so your help is much appreciated. So a 150 - 200 amp alternator should be just fine with a 2 farad cap?

A cap isn't needed if you have a sufficient alternator

What car? What amps are you using, and what are their fuse ratings?
I would for sure start with an alternator upgrade, and also wire a low voltage shut off switch so when your battery gets low, your stereo will shut off. You can wire that into the ignition wire for your cd player only. Thats for when your letting it play when the vehicle is off.

"4000 WATT Lanzar 2 ch amp 2 35 amp fuses",
Something tells me with 70 Amps worth of fusing that amp is no where near 4000W. Lanzar!
