I tryed to splice but was unsuccessful. Then had to buy a new speaker and helmet mount for $50!!! My issue was poor sound quality. I solved my problem by adding very soft foam behind the speakers so they stood proud and were just toughing my ear. It was amazing the sound difference. I hate having ear buds and this is more than enough sound quality for me. The foam I used was from the customizing foam pieces you get with your bicycle helmet.

I've already put some foam behind the speakers and it helped with the volume but the sound quality still leaves a little to be desired. Ive spent big bucks on a zumo 665 so I would like to get some great sound out of that xm.
I have done the earbud mod both ways.
If you cut the speaker wires you will be working with very small wires with an insulation coating that is a pain to remove, solder, and heatshrink. I have done this with 2 units. When I used the speaker wire mod I left enough speaker wire to redo it if I screwed up the first time. This was a good idea as I I screwed up one unit and had cut out the bad soldier joint and do the mod twice. I left enough speaker wire to tuck the extra wire into the helmet lining to protect the soldiered wire joints from stress and movement.
I have done 2 units with the internal mod as shown here

I found the internal mod to be easier and cleaner but a bit more of a risk. I changed the procedure somewhat. For the female 3.5 mm plug I purchased a RadioShack 3.5 mm extension cord and cut the cord about 4-5 inches from the female end. I soldered the wires directly to the circuit board. I used the exit hole for the original speaker wires for the female plug wire. I tied a knot in the female plug wire and ran the wire thru the helmet clamp. The knot will not pull thru the clamp and this stabilizes the cord and serves as stress relief.
The adventure rider mod is well documented. I made up my mod as I went along, use your own judgement.
I have been very happy with both mods.
