I would honestly run a nother cable back up to the negative. I've read ALOT of times people have higher voltage. That picture is wrong.

it should look like

[1st BATTERY +]--{FUSE}-------------------{FUSE}--[+ 2nd BATTERY]

would i need to do the big 3 with 2200 rms?

Doing the Big-3 will ensure that you are passing as much amprage as possible from the alternator to your batteries in an effecient manner. It ALWAYS helps your car, no matter if you have a system or not, or whether that is a 500 wat system or 5,000 watt system, I would do the big-3 on most any vehicle...... Also, your last diagram was ALMOST right.... forgot the one fuse from the 2nd battery positive to the amp.... total of 3 fuses will be needed in total.

Battery's aren't really rated by amps enless your talking about cca, its the voltage, alot of people like kinetic battery's. go to kinetic.com and check it out. If you dont wanna put out that much money then i suggest optima red or yellow tops. Find out what best fits your needs.
