I’ve always had a lot of luck by upgrading to ‘0’ gauge cables. The best are bought at a stereo shop and often you need specific battery terminal connections for it but man what a difference!!

I’ve done this on several cars and it always makes a huge difference

Take a look at this example- much better than anything your going to get at a parts store or reproduction.

Just make sure to loom it… can’t have blue wire under the hood (you can get it in red/black)

I promise you will see a significant difference
