Our take on the T-Spec Power/Ground Cable

by Buck Pomerantz

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.

Is T-Spec 0/1 power/ground wire appropriate for use in the Big 3 upgrade and replacing other large wires in the engine compartment? [ Francis  Feb 24, 2014 ]

  • Yes, but it's overkill for non-audio work. It will work for anything, just cost more than needed. It would be a great choice for going from the battery to your amps as the smaller strands of copper are specially formulated for that purpose. But for going from the block to ground, and from the alternator to the battery - it's overkill. So if you have the cash, then go for it! The power delivery won't be any better than a standard cable under the hood, but it will be a bit less apt to induce unwanted noise. Plus you're getting it all from one place, so it's quick and easy.

  • Thanks! [ Francis   Feb 25, 2014 ]
  • It seems good/capable enough. It is very flexible. That being said, I'd put it in some heat resistant techflex/wireloom to be on the safe side. [ Charles   Feb 24, 2014 ]
  • I connected 1/0 power cable to a box out with 8 garage wire to two pioneer amps I think the 1/0 wire is able handle any power to any amp as long you use the fuze to handle the load [ STEVEN   Feb 24, 2014 ]
