900Watts/ 14Volts = 64.3Amps. I worked for a JL audio dealer and I've been partial to their wires ever since. Especially their RCA's. But knukonceptz have great reviews and they are pretty cheap. I just dont like that they use AGU fuses. Here's a kit from knukonceptz, and it comes with RCA's and speaker wire. This would be perfect for you. http://www.knukonceptz.com/productDe...?prodID=KCA-K4
