High Quality 4 gauge amp Copper wire

[Scarabscott]

Does anyone have a good source for high quality tinned copper 4gauge pos and neg amp cable sold by the foot ? upgraded amp to JL marine MHD900/5 and can't use the existing kicker 8 gauge.

only issue is it doesn’t seem to be tinned copper

I used this non-tinned oxygen-free cable in my 2014. No corrosion after 3 years. For DC current, a higher count, finer strand is my most important feature I want.

Maybe tinned is more important in the salty locations?

Warning: tinned cable must be re-torqued on a regular interval. It loosens over time much worse than bare copper.

Www.Tinnedmarinewire.com decent price and they will even crimp on the lugs and heat shrink everything for you.

Strand count is for the flexibility not current flow. DC voltage does not have a "skin effect" as AC does.

Remember If it is Car Audio size it is not true to spec CA 4ga is = to 2awg cable when buying

Also when they list the max amp on these non CA cables it is at 25'-50' not the 10-15' you would need. But cutting the length in half does not = double the max amp
When looking at fuses you are fusing for the wire/ cable not the amp it's self.
