Product Overview
Stock your next car audio wiring project with the T-Spec V8GT4B-100. This full 100-foot spool contains blue 4 AWG oxygen-free copper power wire with a super-flex translucent jacket. The bulk format is intended for cutting individual cable runs to your layout, whether you are preparing one custom installation or several appropriately sized wiring sections.
Sold as one complete 100-foot spool. Quantity 1 means one full roll, not one foot.
Why Choose the T-Spec V8GT4B-100?
Choose this model when you need 4 AWG OFC wire and prefer blue for cable identification. The flexible jacket supports routing around the planned installation path, while the 100-foot roll provides material for measured cuts. Confirm the length of each route before cutting so you can make effective use of the spool.

Installation & System Planning
Size the circuit for current demand, total cable length, allowable voltage drop and the equipment manufacturer's requirements. Measure the routed path, including service slack, before cutting. Use compatible terminals and a suitable crimping method. Protect the cable at metal pass-throughs and keep it away from heat, sharp edges and moving parts.
Disconnect power before installation. For a battery-fed positive cable, use properly selected circuit protection near the source. Secure the run and verify polarity, connections and the ground path before energizing the system.

Frequently Asked Questions
Is the price for one foot or the whole spool?
One purchase unit is the complete 100-foot spool. This listing is not sold by the foot.
What conductor material does this wire use?
T-Spec specifies oxygen-free copper, abbreviated OFC.
Is this speaker cable or an amplifier wiring kit?
It is bulk power wire. It is not a paired speaker-cable roll or a complete installation kit.
Can I use it for a ground cable?
Yes, where the circuit design calls for 4 AWG OFC. Verify the required size, length and connection method first.
How much amplifier power can it support?
There is no universal wattage answer. Cable length, current demand, voltage drop, connections and installation conditions determine suitability.
Will it fit my amplifier or distribution block?
Check that the equipment accepts 4 AWG wire and the intended termination. Do not trim away conductor strands to force a fit.
