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.
4 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.

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.
MAXI
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.
100A
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)

I trust these kits to have everything I need to complete and install and the wire is always AWG
dominic s on Mar 30, 2015
When it says its for systems up to 1000 watts, does that mean rms? Ill be pushing 800 watts rms and 1600 watts peak with 80 amps, so will this kit be alright because of the 100 amp fuse?
Thanks
Joe D on Mar 2, 2015
Best Answer: the short answer, yes you will be alright. the long answer, yes it will be alright because of the capacity of the wire will tolerate up to 100 amps/1000 watts without trouble. you always want to pick the size of wire and fuse to how much power your system needs, an example is my system, I have a 3 amp setup in my car (2 T400-4 and 1 T1500-1bdcp) the t400's have a 100 amp fuse each and the T1500 has a 200 amp fuse. so in total my system requires 400 amps/2300 watts to run at full capacity but 4awg wire cant handle that much amperage draw so I upgraded to 0AWG wire that can handle up to 500 amp currents and sustain my voltage during competitions. here is a good article to read, http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/what-gauge-wire-do-i-need-for-my-amp/

Will it be thick enough for the Hifonics Brutus X1500.1d ? Or should I go for 0?
Eliav E on Sep 5, 2014
Best Answer: I would suggest using 2 or 0.
Im currently using this kit on a RF T500 @ 1Ohm.
Which according to the birth sheet, is around 800 watts.
