Adria Compact SP
Hi,

I would kindly ask for help. In habitation part of my motorhome Adria Compact SP (2011), there are preinstalled 12v wires. [see attached pics].
I tried to track them and found that it's conncet to the fuse box [front door]. So most probably it should be powered by main car battery. From fusebox it continue to the front [then I am lost]. Can someone help me to make it powered by 12v? Maybe I need to install fuse or ...?

They are speaker wires and run to nearish the headunit (stereo) in the cab. They are not power wires.

So If undertand correctly, it should be connected to my radio. Doest it mean that I just need to connect speakers, or there is some kind of activation of those wires necessary?

No. They are not connected to your radio they are run to NEAR your radio. I assume they are there so you can install, or have installed as an option, rear speakers. I have two sets of wires like yours and think you will have too. My other set are behind a cupboard back panel.

If you choose to use them it would just need wiring into headunit din plug, and speakers installed. You may have to then go into head unit setting and alter the fade (controls front to rear speaker balance) if it has been altered.

Thanks, I really appreciate your help.

I’ve found lots of wires around my van for various uninstalled extras/option.

You may find that the back of the cupboard has a false back, so only held on with four screws. And there they often do the wiring connections. Which nice for maintenance and the ability to add to the system or get a supply.
