Don't spend big bucks on a premium amplifier and then choke off its power supply with low-grade power cable. StreetWires Ultra Flow 8-gauge cable contains pure oxygen-free copper to provide maximum current flow from your battery to your amp. The tough jacket withstands heat and resists damage from abrasion, battery acid, and gas. Super flexible design allows tight radius bends.

This wire is sold by the foot — enter the number of feet desired in the "quantity" field of your shopping cart.
