The 10 Best Amp Wiring Kits

Popular among car audiophiles as well as the average driver, the New England Providore Oversized (about $64) is well worth its relatively high cost. It's one of the few to actually back up its thickness claims, and it's even constructed of pure, oxygen-free copper.

An effective solution for the majority of aftermarket installations, the InstallGear Complete (about $21) lives up to its claim of 4-gauge width, and is protected from surges over 100 amps. It's also available bundled with everything needed for a distribution block setup.

Made to keep heavy bass from straining your electrical system, the Rockville RFC50F (appx. $110) is built around a 50-farad capacitor that mitigates headlight-dimming current spikes. It operates in the 10- to 16-volt range, and it's pretty well priced for such a powerful unit.

With a fit and finish designed to look good in any engine bay, the KnuKonceptz KCA (about $27) is a moderately-priced way to push up to a few thousand watts to your speakers. Its gold-plated terminals resist corrosion, plus, they're a little bit more flashy than most.

Capable of storing a considerable amount of energy, the Rockville Dual Meter (about $170) gives you direct insight into its status at any moment with two bright displays. The actual wiring is billed as audiophile-grade, thanks in part to its double-shielded construction.

The KnuKonceptz Kolossus Fleks (around $125) is a massive, 0-gauge set ideal for high-end installations. Twisted from the purest copper on the market, and tinned for protection from the elements, it's great for any project on land or at sea.

With different models for almost any level of upgrade, the NVX True Spec (appx. $60) boasts top-tier materials that won't pick up interference or break down over time. It costs more than most, but the reliability and build quality are worth it to those who demand the best.

Built for systems of 2,200 watts and below, the SoundBox ECK4 (appx. $20) is one of the least expensive to utilize a reliable, cylindrical fuse holder. Its 17-foot-long, copper-plated aluminum cables are just enough for smaller applications.

Sold in 1/0, as well as 8-gauge versions, the InstallGear SoftTouch (around $22) is easy to work with, and features nearly pro-level performance, at a remarkably low cost. Depending on your selection, it comes with either an ANL or AGU fuse receptacle.

If you can afford it, the Rockford Fosgate RFK (around $181) series is worthy of the brand's great reputation. It's configured to route current from two power amplifiers at once, and unlike some, it's accurately sized to the American standard.
