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.
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.
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.
