Wanted to thank Eileen for a professional transaction and for such a quick turn-around! She is a class act and I highly recommend her to anyone needing some added speaker flexibility for their Scala unit!

Eileen, sent you a PM also! Thanks

It is really an easy mod...

First thank you very much your instruction were idiot proof as i followed them and succeded.

I just did this mod yesterday after reading and actually having my speakers operating at a very low volume when someone is talking as i couldn't hear anything while they could hear me. music was just ok as if i put the volume up it becomes distorded.

now the problem I forgot to solder the black wire that is attached already to to L to the R on the back of the circuit board.
what are my consequences or problems????? by the way everything works fine and i can hear sound from both ears.

I have never soldered anything in my life and i am usually the guy that the fire departement have to be called in if I am doing any handy work at home. it took me one hour messing with the damn solder to get it to do what I am suppose to be doing but I succeded....I waited until my wife went to bed to do this as she knows my repair skills.
thank you

I know this is an old thread, but I just did a similar hack mod on my g4. I noticed that I had to have the volume all the way up when riding with earplugs, and it was still pretty quiet. The sound quality was awful at that volume too, with clipped base and lots of fuzz.

I decided not to chop up the plastic case, so I just rewired the aux-input 1/8th inch jack that's already on the board to connect to the speaker output wires.

It's super clean and I'll be getting some custom-molded earplug/buds (DIY for $16, not those $400 ones!) for in-helmet use. We'll see how it sounds then!

Ok I started my own thread to see if anyone had done anything similar to this on the Schuberth SRC system, it appears nobody has so looks like I am going to be the pioneer.

I know how to solder but I wan't to make sure I get this right for obvious reasons!

So these are the speakers



And these are where they enter the sealed unit



Right,

Q1- Can I just fit a male and female jack inline external without opening the box then just unlpug the speakers and plug in my custom moulded plugs?

Q2. If the answer to Q1 is No, then what can I do?

The problem you will find is trying to solder the fine plastic coated wires. They are very resistant to soldering. The only way to do it is to touch the tip of the wire with a small torch, I use a small kitchen torch.

If you cut the wires you will need to identify the common wire on each side so they can be tied together in an inline jack to the shield, or ring connection. In Cardo's other units the wires are red and green, on one side they will be red with a white (clear) stripe and green with a white stripe. That is the way the G4 and G9 is wired, the Q2's are inconsistent.

Hi thanks for the reply.

So I should be able to cut the wires external to the unit? Could you break it down in simple terms of what I will need to do please?

[JetGrl]

Personally, I would open it up and remove the wires from wherever they go and solder a nice piece of shielded 2 conductor audio patch cable directly to the board. Just jumper between the 2 common connections, usually marked as R- and L- (on G4 and G9). Then install them to an inline 3.5mm jack (do this end first so the wire can be as short as needed).
