no i mean a completely isolated battery in the trunk, the cap would be to give the amp the volts that the battery without the alternator cant put out quick eanough.
1 1211 infinity amp 1300rms and 2 perfect subs if that makes any difference... although i dont usualy crank it. so hard to find a nice sounding system that u can rely on without dumping so much money in it.... *rips hair out of head*

A good HO alt will be a few hundred bucks depending on size.
I don't really understand what the problem is that you're trying to fix...
If you want to play your system with the car not running and always be able to start it the isolated rear battery is a good idea.
If your voltage is dropping a lot when you play the system a bigger alternator is a good idea.
If you have minor fluctuations and minor dimming a capacitor may help you.
If you just want a ton of reserve power dual batteries can work, however if you constantly beat on them and have a very underpowered alternator they won't help much.
Have you upgraded your factory battery grounds and alternator to battery runs? Is your stock alternator performing properly? It could be on it's way out... maybe give us some more info, what car are you driving, and exactly what is the problem that you're experiencing.

96' nissan altima gxe. yes my problem is the alternator cant handle the setup i have now and with the new infinity 1211A amp im getting im sure i will be having bigger problems but i suppose there is no cheap way out of it. where is a good place to buy an HO alternator? i checked partsource and they didnt cary any other than factory level ones
