Verified employee purchase (What's this?)

I bought a new subwoofer, but the ground wire that came with it wasn't long enough, so Crutchfield sent me this one. It's longer than the original ground wire, and I didn't have any trouble installing it. Just make sure you got a good clamp on the wire when installing.

Pros: Longer

Cons: N/A

Flexible, heavy shielding, cut to order. Great wire for replacing factory wire that is the wrong gauge for an aftermarket amp.

Pros: Oxygen free, good shielding

Cons: It's soft, so keep It away from heat.

Customer Q&A

2 questions already asked

Q
What is the bare wire diameter of 1/0 gauge without outer sheathing? Is the 0.625" with sheathing?
[ Paul  Jun 03, 2019 ]
2 answers
A
Yes the .625" is the sheathing diameter. Bare wire directly where it exits the sheathing measured about .388" on the piece I measured. With that said, about a half inch past the sheathing, it measured about .525". The individual strands are tinned, there's a bunch of information for that on the web, but the important bit is that it tends to "fluff" out. If you check the AWG wire diameter table on Wikipedia this wire actually falls between double ought and triple out wire diameters. I had difficulty soldering it in the standard 1/0 connector and have been thinking about redoing it with a 2/0 connector. I hope that helps.
[ Ronald  Jun 10, 2019 ]
A
the inner wire is 1/2" so with the sheathing yes I'm sure its .625"
[ jonathon landon  Jun 10, 2019 ]
Q
What is the ground cable tinned with?
[ William  Aug 15, 2019 ]
1 answer
A
Hey William, the wire is coated with Tin (Sn), the metal, to help prevent corrosion and oxidation.
