Car Audio Installation and Capacitors?

Don't waste your money on a capacitor. They are worthless.

A 220A alternator should be plenty for your batteries and system.

I suspect that the rear battery does not have a good enough ground.

This could be because the grounding point of the battery has too much resistance (compared to the battery in the front). OR

You don't have the correct wire gauge to the rear battery from the isolator.

Think of it this way.

With the car running the alternator is producing around 14.4VDC and can supply 220A of current.

BOTH batteries should be charging equally, Voltage wise (although the larger battery in the rear will take longer to reach it's full current potential).

Do the "big three" upgrade and check the resistance of the grounds between the two batteries.

I will bet this takes care of your problem.

I have a 220Amp H.O. Alternator, a 1900 Shuriken Powercell in the front and a 2400 Powercell in the back.
System RMS is 3600-RMS at 2ohms Bridged at 14.4 volts
The Batteries are separated by a 200-AMP battery Isolator.The rear battery sits at 13.01 volts, just sitting, no draw or charge. The battery Isolator is installed because I don't have 1/0 gauge to the Alternator because it is in the most inconvenient spot, I.E. Ford Escape side mounted DOHC V6

What would it do me, to put a capacitor between both batteries and, and the then another capacitor between the back battery and the amplifiers.

If so, what would you recommend?

waste of money... all you need is your powerful altinator... 2 aux batteries... your cranking battery and 1 isolator... should power it nicly... lol if your lights still hella dim then yea good luck... your better off if possible with your model car getting a 2nd altinator installed or a slightly more powerful altinator
