The black wire that is attached to L- is soldered to R- on the back side of the circuit board...

It is really an easy mod...

Mod

Thank you very much, I use bigear buds and it allows me to have the volume low and still listen to music. Excellent mod.

Good luck!
Hi - I was wondering if you took any pics of your installation mod of the Q2?. Can you provide son guidance with wiring colors etc? How were you able to fit the jack in the unit itself?
Thanks

No, I did not document any of the Q2 modification... It was very different in the wiring if I recall... I do remember that after I got it wired up the music would work through the ear buds, but the phone would not so I had to go back in and reconfigure the way it was wired... I finally ended up trying every wiring configuration with some test leads until I found the combination that worked...

Have some questions for Golevi

Great thread. I am looking to do the same. One question: why do you use 3 wires when the original had 4? Did this change it from stereo to mono?
Why not just cut off the speakers and wire in ear buds to the existing wires? When you removed the speakers and wire did that effect the FM signal since the atenna is in the wire (or so I was told).
I'm not that good with wiring so any information you can provide me with would be great.
Again thanks for the detailed description and photos.
Please shoot me an e-mail and any more information you have to the following.
Rjmurr325@hotmail.com

Thanks Bob

I think I understand and see what you did. You jumped the solder on the back side of the black wire. Again you have to forgive me as wiring isn't necessarily my thing. I'm going to purchase a unit and give it a try.

Btw I am doing this cause I ride with a half helmet and my ears are exposed. Do you see any issue with this? I see some posts that say there is a lot of wind noise if you don't have a full face or full shield. What do you think?

Sounds like you have the wiring figured out... The - is common between both right and left speakers... The reason I did not splice the ear buds to the existing speaker wires is that the wire that Cardo uses does not have conventional insulation on it, instead they use a type of varnish that is extremely difficult to work with...
I do not have any experience with half helmets but I don’t see why this wouldn’t work for you...
Good luck...

What is "varnish"? I've seen that in a few posts?

Varnish

For very small wires, they don't use a typical plastic insulation that you can strip off easily. The thin wires are coated with varnish to keep them from shorting against each other. This lets the manufacturer use very small wires.

To modify these wires - it is a total pain. The varnish must be carefully scraped off to enable the wires to be connected or soldered to anything else. The wires are very tiny and the varnish is hard to see. So you aren't sure when you have a clean wire to work with.

That is what makes this modification so clever - you avoid cutting any of these tiny wires and can work directly on the circuit board inside the Cardo.

A work of true genius! Mine has been working great for several months now.

G4 mounted to a half helmet. HELP!

Ok I ordered the G4 system and will be making this mod. Now the only issue is using it with my half helmet. Any suggestions on mounting it? I don't want a perminent installation. Not looking to tape it to the helmet. I thought about clamping it on with the included hardware but my helmet doesn't have any space to clamp it on. The foam interior is glued to the shell and the foam comes to the edge of the outer shell.
My thought is to fabricate a price of this aluminum to slide between the outer and inner shell with just enough hanging out to secure the G4 to. What do you think?
With this I can slide the unit in and out when I want to use it.
If anyone has installed this on a half helmet I sure would like your thoughts and input.

Aux power for G4

I wonder if one ofbthese would work. The G4 would need to work with power connected. I imagine this would give you 20 hours with no problem.

The G4 uses the near-universal micro-USB power connector (like a Blackberry)

I just got my Scala Rider G4 and will be doing the ear bud mod. I have a question are the ear buds too loud? I read in another forum that the ear buds that guy used were too loud even on the lowest setting? Any input would be appreciated before I mod my NEW G4's.
