This wiring kit is awesome! It may not truly be 0 gauge and 4 gauge, but it is very thick and able to power my 1700w rms at 2 ohms amp quite easily. It has everything you need to install, and has more than enough power cable. Their was not enough speaker wire for my install, but that was because i have 4 subs, it should be plenty enough for two though. Overall, awesome product and would recommend anyone looking for a cheap, yet awesome wiring kit :P
