Price Range
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.
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.
Speaker Wire Included
If speaker wire is included, the value will be "Yes" and if no wire is included, it will read "No".
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.
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.
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.
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.
