Tsunami 1/0 & 4 AWG Dual Amp Wiring Kit

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.
1/0 gauge
Power Wire Length
This is the length of the power wire in feet.
17 feet
Power Wire Color
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".
Remote Wire Length
This is the length of the remote wire that is included with the item.
17 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.
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)

Not 1/0 gauge!

September 30, 2011

If you measure the cable with a micrometer it is not 1/0 AWG it is 2 AWG. The printing on the cable states 1/0 AWG, but it is false.

These wires are great tough and thick but it could be too thick because it doesn't hide well under the carpet but should be durable if installed really well

Great Kit but wrong distribution block

August 1, 2011

The distribution block sonic had listed as a fix for the previous complaints didn't arrive. Well, tsunami has not fixed the problem because the 0 gauge wire does not fill in the supplied distribution block. Thanks to sonicelectronix for sending me the right part at no charge. That is why I order from these guys all the time.

Tsunami AMP1040D

November 5, 2010

For the first time, Tsunami and Sonic has let me down. I was disappointed to say the least. The distribution block was NOT what I expected in reference to the description on the site. Was not sized properly to accept the 1/0 power wire. And When u make it work, the cover doesn't fit! What about the 1/0 ground that was included? what are you to do with that with no ground distribution?.? Oh well, Disappointing! Wire was adequate though.

Some flaws, but still a good product

September 1, 2010

The fused distribution block is not sized properly for the 1/0 AWG power wire. It should have been 1-2mm larger to make it easier to insert the wire. I used a bread tie and wrapped it around the exposed wire as close to the end as possible to make it easier to insert. As you push the wire in it will cause the bread tie to slide down where you can then remove it. If you use this trick you will be able to get all the wire in the distribution block.
A ground distribution block should have been included in the kit. Sonic needs to update the description of the Kit with pictures to match. The kit listed is NOT the kit you will receive. Look up the kit on the web and go by that description. It will be much more accurate than what Sonic has listed.

The Power wires are the best part of the kit and meets or exceeds the defined AWG listing.

this wire is amazing...its heavy duty for real. the insulation on it can withstand a lot apparently. the distribution block what came with my kit wasn't able to handle the 1/0 wire from the battery, I had to clip some ends off to make it fit. good thing I don't have a too large of a current running through it.

i'm happy with it

November 28, 2011

cheapest good dual amp wiring kit on the market
yea you could buy everything piece by piece and spend less but it worth the 10-20 extra so you don't have to hunt everything down and it all works together

well its kinda a con. the 0 gadget wire is exactly the same outside diameter as the inside diameter of the fuse and splitter blocks. Other people have wined about this but if you take your time and push slow and gently you will be fine.

Best value 0 gauge amp kit!

February 5, 2012

I heard decent things about tsunami, and typically all my wires have been stinger, but i decided to take a chance and save a few bucks. Well, when I got this in the mail, I was really impressed with how flexible the wire was, and how much came in this package. I had enough 0 gauge to get from the front of my car to rear, and was able to ground my 2 battery with ease. It didn't have quite enough to do my entire install but when stinger wire is $6 a foot for 0 gauge at my local shop, (this kit has 17 feet) I would have paid $102 for just the 0 gauge wire. I also got a nice quality fuse holder (a little bulky though), and some 4 gauge for my second amplifier. I didn't end up using the distribution block, because it was 4 gauge input, and 2 8 gauge outs, and my sub amp took 0, and my 4 channel takes 4 gauge. But overall I'm happy with Tsunami products and would put their wires right up there with Stinger and Knukonceptz wire.
