SPL lovers

Getting tired of replacing your power fuse every time you show off how loud your system can play? You should consider replacing the fuse holder with a circuit breaker. T-Spec's competition-grade circuit breaker protects your wiring and vehicle with reliable, fast-acting, spring-loaded disconnection when sensing a short circuit or over-current condition.

Valet stereo security

A circuit breaker also allows you to disable your expensive audio system, so no one can mess with it when you park in an attended garage, use valet parking, or leave your vehicle for detailing. The breaker accepts 1/0- to 4-gauge wire and features 24-karat gold-plated conductors for corrosion-free connections. You'll need Allen head wrenches to install this circuit breaker. Warranty: 1 year.

Product Research

Features

Overview: This package includes a T-Spec v12-series, 24K hard gold plated circuit breaker, housed in an impact-resistant polycarbonate cover. The circuit breaker has a rating of 180 amps, and protects your vehicle and electronics without the need for constantly changing blown fuses. If a short circuit occurs, the circuit breaker will safely and instantly disconnect your electronics. A red lever will indicate that the circuit breaker has activated. To reset the breaker, simply return the lever to the normal position. A manual disconnect button is also included to allow you to break the circuit whenever you want. The base has two holes to allow you to mount the circuit breaker with screws or wire ties.

Wire Connections: The circuit breaker will accept either 1/0 AWG or 4 AWG power wire. The wire is attached to the circuit breaker with Allen-head set screws, located below a snap-on removable cover. A 3mm Allen wrench (not included) is required to tighten/loosen the set screws.

Works great!!

Crutchfield Customer Review (What's this?)

This circuit breaker works great. Accepts my 4 gauge power wires and if an upgrade is ever necessary, goes up to I/0 gauge. Much more compact than breakers I've used in the past.

Pros: Compact size

Cons: None as of yet.

hard to find
