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.
4 gauge
Power Wire Length
This is the length of the power wire in feet.
25 feet
Power Wire Color
Ground Wire Length
The length of the ground wire in feet.
11 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.
18 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.
4 Channel
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)

Digital amp readout never has worked!

August 13, 2012

The kit is great except the digital amp readout. No big deal but it would be great if it worked. Everything else in this kit is great!

Installation wiring for two amplifiers

December 14, 2011

I purchased the Tsunami wiring kit to install two amplifiers that I had taken out of an old car to put in my current car. I have a four channel Alpine amplifier that I was installing to drive the front and back speakers in my car stereo environment. The amp will be driven from my new pioneer head unit with rca amp outputs. I also have an Alpine amplifier to drive the sub woofer mounted in the trunk. This unit supplied all the wiring to go from the battery through a fusible link and a voltage display to the amps. A junction block was provided to split the power to the two amps. A control wire was provided as was the rca wiring to drive the amps. The ground cable was provided that connected to the car ground, also a junction block and wiring to connect the ground to the two amps. Last speaker wiring was provided to run to the speakers. The wiring was heavy duty and the instructions adequate for me to do the job although I had never wired this set of equipment before. (previously the amps were professionally installed). The only two extra items I needed was a wire to drive the subwoofer and another RCA wire to drive the input to the amplifier driving the subwoofer. This was exactly what I needed and worked out very well. I would recommend this product for a similar installation.

Great kit for installing a pair of amplifiers

May 20, 2012

This kit worked out very well for me to install a pair of amplifiers in my Toyota Matrix. I have never installed speakers and a pair of amplifiers before. The install went well thanks to the kit having all the wire and connectors that I needed with a couple of unique exceptions. The kit included fuses for the major power lines. If I have a problem in the future these fuses will be good insurance. It also had a display that I mounted in my engine compartment that displays the voltage reading of my car battery. This is a way cool addition. The extra wires that were not included were because I needed a new wire for my subwoofer and I needed an extra RCA cable from my head unit. I am very happy with the kit and very happy with the install.

Amp wiring kit

January 5, 2012

A few issues with this product: 1) The LED display of the fuse holder didn't work requiring me to box it up and send it back. Really annoying having to a brand new amp and can't listen to because I'm waiting on a single part to be replaced. 2) I wired a 5-channel amp which means I needed to purchase one more set of RCAs. Long story short Sonic doesn't sell an individual RCA to match what comes with the kit. In order to have everything match I had to buy them individually.
