Thanks for the replies and links. Waterproof sounds like the way to go. The Deutch connectors are waterproof, right? Neal's link to that EBay store has them for 10 gauge power wiring. The guy says he doesn't sell a crimping tool for it though. Is one really necessary to assemble the connector? Can it be done without one?
BTW, is waterproof really necessary. HD doesn't provide waterproof connectors for all their stuff. The LED saddlebag lid spoiler connectors are not waterproof. That's the only electrical add-on I have to compare too. I imagine it's more critical with an audio power connection.
I'll have a LED KTP spoiler (brakes/tailights) and interior TP light to power, besides the audio signal wire. Can these be combined into one Deutch connector? If I can power the amp's 10 gauge with one, and put all the other connections on another, it won't be too cumbersome using 2 plugs. I'd hate to have 4 electrical plugs for this.
Thanks again for your help gang!

Hoist!
