Looking for a little wiring advice fellas. I installed the "upgraded" Shark 250 watt system (suuposedly). Anyway, since the subwoofer was cheap I ordered it. I spent a couple hours trying to get it wired up cleanly. Hot wire to battery. Grounded to a ground wire I located just in fromt of the battery box (black with a yellow stripe). There is a white wire with green spots next to the ground. I was hoping it was an accessory power wire, but it has no power to it. So, I need to wire the woofer to a switched circuit so the darn thing will shut off. Has anybody else installed the subwoofer? If so, where did you wire the switch up? Any ideas would be great, please be specific. Just telling me to wire it to a hot wire doesn't help me know where to tie in at. I also ordered extra speakers for $6.00 a piece. I just wish they would have come with mounts. I'll post pics of the install soon. Mounted the amp/radio on my handlebars. Easy to shut off, just hit the power button.
