The simpliest way I have found is (this is simplar than I am making it sound)
Basicly I tied into where the speaker wires plug into the speakers
I wanted everything to plug in and unplug so:
I made a Y connector (two female and one male ends) with extra wire speaker wire and some spade connectors.
Using the Y connector: Plug the stock speaker wire into the male end, then one female end into the fairing speaker
and the other end into a speaker wire that I had gotten from radio shack (that was speaker wire that had a male RCA jack end - that's all they had) you will need to add a spade connector to one end.
(or just soder the headphone wires to the stock wires)
I had a double RCA female coupler
This plugs into an iPod 3.5 adapter, like a Pyle (PLIPG1) iPod 3.5mm Stereo to RCA Adaptor
The white wire in the picture is unused
I did not want to drill a hole anywhere and this one sticks on with body moulding tape.
When you order one make sure it's black, a lot of them are white.
Once you get settled on what and where you want it and want to drill a hole, this is a black water proof one:
I originaly mounted it on the fairing but the headphone wire kind of dances around in the wind, so the second time I ran some wires under the gas tank and ran the wires back to the battery area and mounted the iPod headphone jack to my heat shield. Now I don't see the wire dancing above the gas tank.
I guess I need to take some real pictures and do a write up. lol
With this setup I use some Skull Daddy ear Buds and I can hear perfectly. Even soft pop/rock.
I have the AVC on 2 bars and never get above the third bar on the volume.
Way better than any speaker/amp setup and I've been the 6 1/2" speakers and 360 watt setup route. I still couldn't hear it clear enough at 70 into a head wind with the big amp and big speakers.
This should all cost less than $30
