Thats good. Hopefully Monday I can give them a shout and see if I can buy just the cable. I bought off of amazon, and researched on Kicker's website and a few others, but none of them mentioned the long and short cable.
Of course, that's why it's better to go with a specialist (like Earmark Marine or MLA) in the first place. Think of all the other areas of information you are missing out on that could make your system better.
