Evening all...I've spent around 4 hours wiring in a sub to the Bolero (I think...) in my SE TDi, Installed a line out converter to get RCA outputs at the quad connector spliced into the circled wiring... Surprisingly it only took around 10 minutes to get power to the rear!

 

The amp has power, but no sound. I've tried a different amp and speaker but nothing from any combination so my guess is a problem with the converter wiring? I did go for a Halfords Special for it so it may well be faulty, but then I could have made a simple error...all wiring was new today, switched live taken from fuse box, double checked polarity of speaker connections and all looks correct. Went a bit cheap on the converter because I'm planning on replacing the headunit soon anyway, just felt like having a little more bass beforehand as I already had the sub and amp to install already, both worked fine in my previous car...

Does your Octavia have Canton? That uses a digital output and I *think* that means the analog outputs are disabled.

Sorted, turns out 2 of the connections were slightly inadequate!

 

For the canton systems, i think the speaker terminal block is missing from the quadlock as it's controlled by the seperate underseat unit? Never had more than a basic stereo as a stock item, it was a surprise to see this one had DAB and Bluetooth to be honest!
