Amplifier installation kits can save you time and money when installing an amplifier in your vehicle.

Amplifier wiring kits come in various gauge configurations depending on the wattage of your sound system and include all the necessary components you need to successfully install an amplifier.

This Kicker 4 Gauge Power Amplifier Wiring Kit includes all the necessary hardware and wire to power one amplifier and is designed specifically for car audio systems up to 1000 watts. The included premium power/ground cable is made from 100% oxygen-free copper and is true-to-gauge for ultimate power transfer.

Amplifier Kit Specifications

Amp Kit Type
Amplifier installation kit come in two different types: Power or Complete. Power Amp kits are designed to only provide power to the amplifier. Complete kits will provide power and signal to the amplifier. Many of the complete kits will also include speaker wire to connect the amplifier to the subwoofer.
Number of Amplifiers Supported
This is the number of amplifiers that the amplifier kit can support. If you are are going to be powering more than one amplifier, make sure that the installation kit will support them.
Power/Ground Wire Size
The power/ground gauge numbers represents the main wire size of the amplifier kit.

Definitions are as follows:

Gauge (wire) - The diameter of a wire. The higher the number, the thinner the wire. Example: 4 gauge wire has more strands than 10 gauge wire.

AWG (American Wire Gauge) - A standard of the dimensional characteristics of wire used to conduct electrical current or signals. AWG is identical to the Brown and Sharpe (B & S) wire gauge.
4 gauge
Power Wire Length
This is the length of the power wire in feet.
20 feet
Power Wire Color
Ground Wire Length
The length of the ground wire in feet.

Speaker Wire Included
If speaker wire is included, the value will be "Yes" and if no wire is included, it will read "No".
Speaker Wire Length
This is the length of speaker wire that is included with the item.

Remote Wire Length
This is the length of the remote wire that is included with the item.

Interconnect (RCA) Signal Cables Included
Interconnect cables are required for amplifiers which are installed to the "RCA preamp low-level outputs" of a car stereo receiver. If your amplifier has high-level / speaker level inputs, then you do not need to purchase interconnects; however, interconnects offer a much higher quality sound when compared to speaker level inputs.
Fuse Holder
This is the type of fuse holder that is included in the item.
Distribution Block Included
This means that the kit includes a distribution block in the package. This will assist in the installation of the amplifier kit or any situation where a distribution block is required.
Complies to AWG Standards
Since 1857, The AWG (American Wire Gauge) system has been the standard for measuring the diameter of wire. AWG standard is the measure of bare wire to find true gauge. Companies that do not follow AWG Standards include the thickness of the wire jacket which means the actual wire is not "True to Gauge". For the best performance from your amplifier wiring kit, make sure that the cable complies to the AWG standard.
Wire Material
The material that the wire is made of. Copper & aluminum are the most commonly used materials. OFC - Oxygen Free Copper is the ideal choice for wire material. Copper is a superior electrical conductor, & does not expand or contract with heat. CCA - Copper-Clad Aluminum is a suitable choice for lower powered or budget applications. The power transfer is not on par with OFC, but this material offers significant savings.

does what it's supposed to

January 20, 2014

This is a length of 4-guage wire and an inline, 80-amp fuse basically. Not much to go wrong there, although I did blow the fuse but that was my fault. After properly connected, it powered up my 1200W Kicker CX600.5 amp and it drives two mid-range bass and a subwoofer with no problems.

Oh, God yes.

February 21, 2015

Handles the power from my 500W RMS Kenwood KAC-9610D just fine. I absolutely adore the blue fuse, as well. All the wiring is very thick and heavy - exactly what you want if you need your sound system to spit fire.

Kicker is a good brand and it has all the wiring you need in one kit.
Chris B on Mar 2, 2015
For the power cord where do you cut the wire for it to go into the fuse or do you pull apart the black and blue where they connect?? I assume the black portion of the power cord hooks up to the batter and the rest gets fed back into the amp.
JoshB on Jan 5, 2015
Best Answer: The black wire is your ground.

As far as where you cut the wire for the fuse, that is completely up to you. It is most common to place the fuse under the hood of the car. To install mine, I cut the wire about 18" from the end to place the fuse in. This kept the fuse close to the end of the cable, easily accessible, and gave me room to maneuver the wire around the battery box.
