4 AWG will work fine for your application, in stretches of a couple of feet good OFC wire can handle 150 amps of current, However 1/0 would be good if you don't want to come back later and redo it because you are upgrading your system.

on a factory alt/electrical system you will see lower overall voltage trying to run more then one battery and when it does drop down during long play it will take twice as long for your overall electrical to recover.

that delco is just a normal car battery. you need to do a big three and a battery upgrade. I prefer Optima Yellowtops because of the ease of returning if something does go wrong with the battery but expect to pay 200+ for it.

The Delco is a "Starting" battery. You need a good AGM or Gell Cell deep cycle up there that can take being drawn down quicker and charge quicker than just a regular cranking battery....I went through 2 or 3 before I went ahead and spent the $$ on what I needed.

Like everyone else said, a Big 3 and a good batt will help cure the headlight dimming. This is what I did on mine with a 1200 watt amp at one ohm. A Yellow top Optima is a good choice. And like others here will attest, if you have a problem with a Optima, you just take it to the nearest Napa/O'Rielley's/ABC/Autozone, etc. and usually do a swap with no hassle.

Do the Big 3 and see what happens...

there was a guy up here a few months back that found a online sale at advance auto he paid 150 online and then drove up to the store and picked it up, no shipping needed just pay online, but what one are you looking at mine was 190.00 with tax and it's the larger one if I'm not mistaken(g35)but still fits in my 02 corolla even though the website said it wouldn't?
