True 4 Gauge

Crutchfield Customer Review (What's this?)

With cheaper kits you get inferior quality. This kit comes with great parts, albeit it's a simple kit. The wiring is a true 4AWG cable, not a 6AWG wrapped in thicker insulation to seem like a 4. I ran this power cable from the battery of my 2005 Subaru Outback to the rear section with a few feet to spare. Powering two amplifiers through a 2 farad capacitor there's no headlight dimming at all. The connectors in this kit are top quality. Highly recommended.



Great Choice for Me

Crutchfield Customer Review (What's this?)

I was installing a Kicker system on a pontoon boat and I needed a 4 gauge power & ground cable. This worked perfectly. I already had most of the connectors, so everything else in the package was just a bonus, including the fuse/connector that I didn't have. This was the least expensive "kit" I could find.

Crutchfield Customer Review (What's this?)

They pretty much do what they say they do. They come with instructions in the packaging and you can call Crutchfield tech support for extra help. The only bad thing is that they don't come with a RCA cables so I had to by my own. All the cords were long enough for my 2005 Sunfire and my amp in the trunk. I'd recommend this kit if you don't need RCA cables (patch cables).

Product Research


General Overview: This is an amplifier wiring kit that includes the power and ground wiring and accessories required to install a car amplifier with a amp rating of up to 400 watts. It does not include speaker wire or signal cable.

CCA Power/Ground Cable: The power and ground cables are built from 4256 individual strands of the purest oxygen-free, fine-stranded copper. The cables feature highly flexible Rope-Lay wire construction to prevent kinking and provides more installation options. The Poly Flex insulation offers protection from heat, and chemical reactions from gasoline, battery acid and oil. This 8-gauge wire has a temperature rating of 105 degrees Celsius.

In-line Fuse Holder: The supplied in-line AFS fuse holder features an impact-resistant clear housing to protect the fuse while allowing easy fuse inspection. The set screw inputs and outputs accept bare 4 gauge wire. It has a mounting base plate and mounts with four screw holes for mounting (screws not provided). The Three-Stage Watertight System utilizes four O-rings for a perfect waterproof seal. The solid machined contacts have a silver-plated finish.

AFS Fuse: The supplied 80-amp AFS fuse is to be installed in the fuse holder. Be sure the 80-amp AFS fuse rating is adequate for your installation. (AFS fuses are available up to 150 Amps, if needed.)

Accessories: The wiring kit also includes a 16' spool of 18-gauge blue turn-on wire, two 4-gauge spade terminals, one 18-gauge spade terminal, and an 18-gauge butt connector.
