Stinger Makes a Great Wire
Crutchfield Customer Review (What's this?)
I was a bit skeptical about paying for "premium" wire after having used some 14 gauge wire from eBay for a long time. While this stuff is somewhat expensive, the price is justifiable for the quality that you receive. The wire itself is very high quality stranded copper. I have had no issues with conductivity and the cable itself is very flexible and easy to maneuver. The sheathing is very thick and feels like it will stand up to a lot of abuse. I had it getting scraped against sheet metal edges in my car during install, with no discernible damage. I liked this wire a lot so I ended up purchasing the 16 gauge version for a different car. I would definitely recommend this over generic, low quality wire.
Pros: -Sturdy sheathing -Holds up well to damage -Very flexible and easy to run
Cons: -A little bit expensive
