Hello all and welcome to my quest to improve the sounds in my Mk3 Octavia VRS that is fitted with the MIB1 Bolero unit. 

 

I have seen these and think this (or similar) may be the solution I am looking for.  http://www.amazon.co.uk/dp/B00630K09C

 

I can wire that to a power feed coming from the fuse box. I will also need some sort of on-off control coming from the Bolero. Then I need the audio input. I have seen some info on the rear connections on the Bolero unit that is fitted in the glove box. There are possibly AUX OUT connections - does anyone know if these work, and if so does the amplitude vary with the main volume control? I don't really want to tap into the existing speaker wiring with high-level to low-level converters.

 

Thanks

That looks like a cheap copy of the older focal or rainbow unit.

All of those type active subwoofer's have 'high-level' inputs, I would recommend using these and you really should tap into the rear speaker lines out of the unit. If you're lucky that model will have signal sensing (no need for a switched supply), the better branded ones that it's a copy of do so.

Then either battery supply at the battery or the main feed into the fusebox should suffice, they usually only have a little less than 10amps draw anyways.

Thanks. I went to try and find the pin-out diagram I came across before, and while I found a few that indicated AUX OUT pins, there were plenty that labelled these AUX IN instead. Thinking about it the Bolero does provide the aux input and there is no use for an output - so this idea is probably not worth pursuing. Using the high-level speaker outputs for the rear seems to be the only option as you say.
