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.
Complete
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.
1
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.
8 gauge
Power Wire Length
This is the length of the power wire in feet.
17 feet
Power Wire Color
Red
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".
No
Remote Wire Length
This is the length of the remote wire that is included with the item.
20 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.
AGU
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.
40A
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.
No
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.
Yes
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)

Great Kit

June 20, 2012

I did not purchase my kit through Sonic, but I wish I had. It's way less expensive here than at the local shop. I used this kit to install an amp in my car about 6 months ago and it's still like new. I get about 0.25V drop at 40 amps with a 16' run of power wire and about 3' of ground wire. High quality 8-gauge is plenty for a system that draws less than 50 amps. I love RF products. Always great quality.

Solid Amp kit

December 20, 2011

Great amp kit at a resonable price. Power cable is made with copper and the rca cables are solid built. The kit says the rca cables are 20 ft long but they are actually 17 ft. the kit provides the power needed to run a 500 watt amp.

Good quality

November 6, 2011

I got this wiring kit from B*stB*y a few years ago and its a great kit. Everything is included and its of good quality. The wiring seems to be of correct gauge, and the only problem I've had is a blown fuse and the need to upgrade due to a system upgrade. If you need an 8 gauge amp kit, this is a great kit. Although there are probably better deals here on Sonic than this specific kit.

The BEST 8 awg around

September 9, 2011

I would highly recommend this kit because not only is it true to spec quality wire, but in this kit comes everything you need to get started. Most people overlook wiring when purchasing systems, but this wire will keep you running safe and cool. It handles up to 500 rms!

Excellent kit

Great kit. Wired my 200W amp and sub in no time and sounds great. You don't need anything else. High quality wires. Very flexible. Can't beat it for the price for certified copper and not CCA.

Amazing

November 9, 2010

Although it says 8 gauge, its closer to 4 or 6 gauge wiring. The power and ground cables are extremely bendy, you can tie knots with them! Powering a 900 watt amp with ease
