Did run into one problem. One of the two supplied wires for the volume knobs is not long enough. I don't know why, but one is 6' and the other is 14'. Obviously to reach the helm they both need to be around 14'. It's weird wire too, a 6 pin type data cable. 6 pin phone cord doesn't work, and no one that I can find sells this stuff. I know literally nothing about network cable. I think it's some sort of Cat 5 or 6 cable, but with a telephone sized jack. Not a standard cat 5/e/6 sized jack. Friggin nightmare. I can't even find it online. Don't really want to get into buying a crimping tool and making my own either if I can avoid it. Of course Kicker is closed today too, so they can't help.
