I need to know what kind of amp kit and speaker wire to get for my 2 12" kenwood W3012 subwoofers (400 watt continuous power and 1200 peak) and kenwood 9104D 1800 watt amp. I have an aftermarket stereo and it has subwoofer crossover (as in the aux ports behind it) and subwoofer controls built into the radio. I have been told to use 0-4 ga battery and ground wires and 12 ga speaker wire. If at all possible i would like a quality kit but for no more than $100 but more to my suiting of around $50. Any help will be appreciated.
