This wire meets the highest specifications

Your car's electrical system supplies serious current to your amplifier, so it needs low-resistance wiring in order to deliver its power effectively. T-Spec's power and ground wire meets all American National Standards Institute (ANSI) and Consumer Electronics Association (CEA) standards for size, resistance, and insulation quality. With T-Spec wiring, your amps and speakers will get the energy they need to give you peak performance.

Oxygen-free virgin copper

Recycled copper often contains impurities that can impair conductivity, so T-Spec uses only oxygen-free non-recycled virgin copper in their wire to maximize signal and power flow. The high strand count of this cable and its special PVC blended jacket give it an extraordinary flexibility, making installation easier. Boat owners, this power wire is marine certified, too. Warranty: 1 year.

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