    Big 3 upgrade kit

    Posted by Art on Sep 29th 2021

    High strand, very flexible 1/0 gage wire. Perfect for big 3 upgrade. My oem cable, battery to alt, was too short due to engine swap and alt/battery on opposite sides of the engine bay. I was able to order custom length power cable.

    I highly recommend gpaudio's kit. One thing to think about is if you plan to add a fuse or breaker between the battery and alt, you'll need 2 extra copper lugs. Just easier to order everything at once and save on shipping vs making multiple orders.

    Great people, and great wire.

    Posted by Daniel Cole on Sep 1st 2021

    I had ordered the big three kit from GPcaraudio.com and some of the cable was back ordered so one of the reps CALLED MY CELLPHONE to give me a couple of options. In a day and age of terrible customer service. This was OVER THE TOP! GREAT customer service. I ended up opting to wait for the back order cable and I am glad I did. It's perfect high quality like it should be. I will order all of my stuff from GP from now on. Thanks again guys I appreciate it!

    Great stuff

    Posted by Fink on Mar 29th 2021

    Bought for my Chevy S10 to go with the high output alternator I just put in. Smoothed out my voltage gauge when the HVAC and electric radiator fans kick on, and might have helped smooth my idle a little bit too. Cable was pretty flexible for 1/0, and there was plenty of it. Only needed half for my S10, so I'll pick up a few more lugs and add some more ground cables for redundancy. Probably have enough left to tie the battery to the body, and then tie engine, body, and frame together as well. Unnecessary, but overkill never hurts with grounds. I'll probably order cables here again when I'm ready to add a second battery and/or front and rear winch connections.
