I was planning on purchasing this item to wire in my two amps (Bazooka 500x1 RMS and a Visonik "800w" peak). I am on a tight budget so I was looking for the best bang for my buck. After reading the reviews, I did a little research into the MM sizing of this wire. I have discovered two things. First, I discovered that when they are using MM for wire gauging, they must be using it as MM squared since it is the closest in relation to the chart. Second, it is stated that the 0 Ga wire is "15.5 MM", which would actually make it closer to 5 ga AWG (4ga: 5.19mm, 21.14mm2;
5ga: 4.62mm, 16.76mm2; 6ga: 4.11mm, 13.29mm2) and the 9.5mm would be closer to 7-8ga AWG ( 7ga: 3.67mm, 10.55mm2; 8ga: 3.26mm, 8.36mm2) I am not writing this to discourage the purchase of this kit since it has many great features for the money (Batt. Term, fused Dist. block, H.D. ring terminals), BUT I am writing this because of the notation about it being "true" wire gauging. I have used Scosche products before with no issues, but that was with one amp. Now installing two amps, I want to be sure of how I am wiring them to prevent any issues. After using a conversion chart, I think I will find another kit that IS true AWG!

If you need 0-2 gauge wire don't buy this. The O is actually 4 and the 4 is actually 8. the d block and fuses all seem decent. the remote and speaker wire is trash. The rca's are the most bottom of the line. but i guess you get what you pay for. spend the extra 20 dollars

I bought one of these kits a while ago its pretty good wire but its not real gauge the 0 gauge is around 3 gauge a lil bigger than 4 gauge and my kit didnt have the TWO 0 gauge crimp ons that you see in the picture. Overall its good for the price.

Great wires for the price but if you look at true 0 gauge it is much thicker... But these are quality wire... I would not recommend using these on over 1500 watts

Great wiring kit for a dual amp set-up. The wires are nice and flexible, even the 0 gauge bends easily. Fuses included are a bonus.

The only few problems i have are:
split loom is not made for the 0 gauge(which is coincidentally the only one needing split loom in my install)
grommet is too small and in crappy plastic - had to buy my own.
would have loved for them to include some 0 gauge grounds wire with a grounding block.
