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.
1/0 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.
Fuse Holder
This is the type of fuse holder that is included in the item.
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.
OFC (Oxygen-Free Copper)

Just arrived yesterday, so they have not been installed yet but impressed by first looks

August 26, 2015

I just bought these cables to run 2 12'' pioneers with a 2100rms class D amp, the wire is very good in size ( actual copper inside not just a oversized rubber surround) VERY flexible for the thickness it is and came with everything needed for a proper install. The only thing I would say needs improvement would be the fuse holder, it seems like a cheap plastic cover that has huge gaps on the side that could possibly be an issue if the right conditions were presented such as water somehow following the wire into the fuse holder which shouldn't happen to begin with but you can never rule anything out with cars in general especially when it comes to audio products. Overall nice kit though and would defiantly recommend to others, ( maybe get a different fuse holder if you want to be completely safe though)

Way cheaper here than at my local shop for the exact same thing. Very flexible and easy to install, only question is the thickness of the wiring, about as thick as ten year old ofc 4 gauge wire I have laying around. I guess they make the jacket thicker these days to have the same appearance as wire of old, regardless it works.
