Metra 12ft Heavy Duty 12-Gauge Car Audio Subwoofer Speaker Wire

I've used this wire on numerous installs for years. It's a very good quality wire. It's a bit stiff when you first use it but it more than makes up for it with its quality.

Excellent product for the price. Doesn't feel cheap or of poor quality. The wires are a little difficult to separate from each other but that in itself shows the quality of the coating.
