Just a question about some hard-wiring. I've already hardwired my RD above my mirror with the direct wire smartcord so that's all set. Now I need to hardwire the external speaker and find a good place to mount it. However, I want to go a littler further and hook a switch up to the external speaker because I don't want it on all the time, only when I'm listening to the music real loud with the windows open (figured it'd be smoother to have a switch than to unplug and plug it in every time).
Here's the problem: Every switch I look at has three hookups to it:
1) For the power source (From the power of the car)
2) To the powered accessory (to the speaker)
The external speaker has three wires....the wire that hooks directly into the radar detector (easy), the power wire, and the ground wire.
How do I hook it up?
My guess, and tell me if I'm right, is as follows:
The switch AND the speaker need to be grounded so I will need to buy some wire to ground the switch. Therefore, each ground wire will be grounded to the chassis of the car separately.
As for the power wires, assuming the power source from the car has already been established (cigarette lighter wire or what not) do I just cut the power line of the speaker in half, or somewhere along the length, and lead both of those cut ends to their respective spots on the switch? (The wire leading from the car's power source would hook up to #1 and the power wire from the speaker would hook up to #2)
Does this sound right? Has anyone already done this? If this works out, I'm thinking of doing it to my RD also. I have a good spot for the location of the switches in the center console.
