When it comes to delivering clean, reliable power in a high-performance audio system, nothing is more important than the wire you choose. GP Car Audio’s Tru Spec wire is engineered for builders who understand that voltage, current flow, and true gauge copper make or break a system. Cheap, undersized cable starves amplifiers, creates voltage drop, and limits overall performance. Tru Spec wire solves that by giving you full-size OFC cable with extreme flexibility, ultra-high strand counts, and the durability needed for real-world installs, demo builds, and competition systems. If you want the strongest electrical foundation for your system, this is where it starts.
Why Tru Spec Wire Is Different
-
True-to-Gauge Copper
Many “1/0 gauge” wires aren’t truly 1/0 once you strip the jacket. Tru Spec wire meets real AWG standards so you get the copper you’re paying for.
-
OFC for Maximum Conductivity
Oxygen-Free Copper provides lower resistance, better voltage, and stronger amplifier performance compared to CCA wire.
-
Ultra-High Strand Count
More strands = more surface area = better current flow. This also creates exceptional flexibility for routing through firewalls, under carpet, and around tight bends.
-
Extreme Flexibility
Tru Spec wire bends easily without kinking or fighting the installer — a night-and-day difference from stiff, cheap CCA cable.
-
Heavy-Duty Insulation
Thick, heat-resistant jackets protect the conductor in harsh automotive environments while still maintaining softness and flexibility.
Performance Benefits of Tru Spec Wire
- Stronger voltage delivery to your amplifiers
- Reduced heat buildup under heavy load
- Less voltage drop during big bass hits
- Cleaner bass response and better power consistency
- Longer lifespan and fewer wiring-related failures
- Better performance at high power levels (3,000–15,000W+)
Ideal For:
- Daily bass setups
- High-power demo builds
- Multi-amp systems
- Competition vehicles
- Electrical upgrades (Big 3, alternators, lithium banks, etc.)
FAQ: Tru Spec Wire
What makes Tru Spec wire better than CCA wire?
CCA (copper-clad aluminum) offers lower conductivity, higher resistance, and less flexibility. Tru Spec uses OFC copper, which carries more current, stays cooler, and delivers stronger voltage to your amps.
Is Tru Spec wire really full AWG size?
Yes. Many brands hide undersized conductors inside thick jackets. Tru Spec wire meets or exceeds true American Wire Gauge standards.
Does Tru Spec wire improve sound quality?
Indirectly, yes. Better voltage means better amplifier performance, which results in cleaner bass, stronger output, and more consistent power delivery.
Is the insulation durable?
Absolutely. Tru Spec wire uses thick, heat-resistant, flexible jackets designed for automotive use — strong enough for competition builds, flexible enough for clean daily installs.
Do I need Tru Spec wire for the Big 3 upgrade?
Yes. OFC true-gauge wire is strongly recommended for Big 3 because it reduces resistance and dramatically improves overall electrical performance.
Why do high-power builds rely on True Gauge OFC wire?
High-amperage systems demand consistent current. Undersized or weak wire causes voltage drop, amplifier strain, distortion, and even equipment failure. Tru Spec wire helps prevent those issues by delivering stable, efficient power.
