like it says i got a amp wiring kit from a friend today and he said it was 1guage so i said i would take it! i got there and it was a 4 is this big enough for my car for a remote bat kit?

 

4's a bit small for a remote battery. 2's almost pushing it for the job. a good reference for minimum requirements

 

No. I had about 20' of 2 gauge to my trunk mounted battery. The voltage drop was insane when it was hot especially after I put in the rear cut off switch.

I switched to a 4/0AWG (1/2") setup all of those problems where eliminated, awesome power. Never look back.

Remember when you do a remote battery your alternator + has to go somewhere too. I recommend 2 gauge. I originally had 4g when I first put my battery in the trunk, when I switched to 2g I immediately noticed a difference in charging power and stability.

As a reference you need at least 0 or 00 for a remote battery on our cars. People will try to tell you different. I have tried many different setups and I am telling you what works the best. 2g main is just sub par that's the bottom line never mind 4g.

Black is the 4/0AWG main +, Red is the 2G alt+

 

That is not what I was wanting to hear....... I got a amp kit cheap today(alpine head unit,amp kit $50) I was told it was 1 gauge then found out it was 4. Was going to turn it into a remote kit.

So you can't hook the alt wire to the point where the power wire feeds everything? And I wonder how big I can go until it won't fit under the trim along the door. I really don't wanna run under the car

 

Sorry to be the bearer of bad news but do it right the first time and save yourself $$ and headache in the long run.

You can hook the alt wire up like that but its really not the best way to do it, plus they wont let you run at most tracks like that. Best to have a separate line with a fuse closest to the battery.

0 should fit under trim no problem.

 

I used 2 gauge wiring which is the smallest you should go. The battery is in a BMR tray in the rear of the car where the spare tire used to be. It's an Optima Red TOp battery. The negative is grounded to the frame rail in the back, and the positive is routed inside the car, along the passenger side, under the interior panels through the firewall to the engine bay. It works like a charm and i've never had an issue starting the car or the alternator charging the battery.
