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.
17 feet
Power Wire Color
Ground Wire Length
The length of the ground wire in feet.
3 feet
Ground Wire Color
Speaker Wire Included
If speaker wire is included, the value will be "Yes" and if no wire is included, it will read "No".
Remote Wire Length
This is the length of the remote wire that is included with the item.
17 feet
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.
2 Channel
Fuse Holder
This is the type of fuse holder that is included in the item.
Mini ANL
Fuse Size
This is the size of the fuse that is compatible with the fuse holder. If the fuse needs to be replaced, be sure to replace it with the same size.
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.

I purchased this wiring kit to use with my JL Audio G1700 amp which can only be used with 4gauge wire. All i can say is it was great its a true 4gauge wire and is very flexible so you wont have a hard time with installation. A lot of people tell me it even looks like Monster Cable. I also like the fact that it comes with rcas so i wont have to buy them separate and that its very long. I had enough to wire my whole truck which is pretty big and i still had some left over rolled up under the seat. Overall it was an awesome kit, I would recommend to anyone.
