I got a freebie LOC, its the stinger sgn11, but the input wires are not marked, and I cant find the info online anywhere. Does anyone know how to hook this up?
looks like this:

 

There are 4 wires you really need to worry about which you hook up to the respective signals on the output of your deck, or wherever you find the signal (often people take signal from the speakers in the rear deck because they're easy to access in the trunk):

White Solid - Left (+)
White w/ Black Stripe - Left (-)

Grey Solid - Right (+)
Grey w/ Black Stripe - Right (-)

The RCA ends just hook up to RCA cable that leads to your amp.

Hope this helps!
