Hi, I'm looking for the rear connections schema for my bolero unit (installed on my Octavia III 2013) because I interested to connect it to an external amplifier and replace the original front loudspeaker with new ones, LS 29neo (from Technology) as a tweeter and 18W/4531G00 (from ScanSpeak) as a mid-woofer.

I'm also looking for the instruction or video that can help me to remove the panel on the front doors to replace the loudspeakers. 

 

Thanks in advance

Funnily enough, I'm considering changing the door speakers for aftermarket items when i get my car. I didn't opt for the Canton, but I have had good results just from changing speakers to something half decent in the past. I did this on my old Altea, but that was really easy to remove the original speakers. I have been looking for door panel removal tips as well.

There's a little bit of info here ; http://www.briskoda.net/forums/topic/288090-retrofit-new-columbus/page-2?hl=columbus but not much to go on at this point. I'd be interested in this also.

Hi

Hi, who can tell me what kind of connector is the 5th starting from right, seems to be a dual optical cable .

I think someone has mentioned optical connections on a thread on an infotainment system, yesterday.

Well done on the first phase, still looking forward to the door panel removal. I have sourced some new component speakers, just need to fit them at some point.

From right? You mean those white at extreme left? I bet for the aerial, since I read FM 50ohm "engraved" on top of them.

 

The black one reminds to me ugly toslink... (optical digital out)

Sorry for my error, starting from the left, 5th connection, seems to be the MOST optical connection.

In my experience the biggest issue with canbus units is getting an ignition switched feed to turn on the external amp and getting line level outs (on my Superb Columbus I used a speaker level>Line level converter but the results were poor and I ended-up ditching the amp and just upgrading the speakers (which was better than nothing)) - I believe there was is VCDS re-code needed also to boost the output to make the line levels work better (my problem was there was a lot of alternator-type noise which even putting in an in-line filter didn't fix). Didn't spend too much on the amp (£120) so not the end of the world it sits nearly new in the loft, and inevitably it'll find a use one day.

 

I've upgraded many systems over the years (so hope I know what I'm doing) but for canbus units I'd say visit your local car stereo shop and get their input as they must do this a lot and will know the tricks.  And definitely don't try using the canbus feed (which does go +'ve on ignition switch-on) as a trigger as it causes some weird issues on the rest of the canbus!  When I tried it asked for the radio code (which I didn't have!) - luckily unplugging the feed I'd added undid the damage and no need for the code!  Its a minefield

 

To find the pin-outs is pretty easy (plenty of sites if you Google, such as http://www.my-gti.com/529/volkswagen-rns-510-pin-assignments - I know that's for the Columbus/RNS510, but the pin-outs are the same for power & speaker across all units).

 

Hope this is of some help.
