Hi there.

it`s me again.

I see only one plug with two "wires" into it. I will solder the speaker(or speakers) temporary to these points whitout plastic plug. The question is how to understand where to put + and where minus of the Speaker and how many Ohms it should be.

The TV is grundig davio 15-5710
The board with audio port and TV tuner is XKU190R-9

thanks in advance

 

It uses a TDA7056 chip, that has a 16 ohms speaker..

The Chip Uses Bridge Output, which means the speaker doesn't connect to ground, it goes between the chip outputs.

Probably worth reminding the TS that the TDA7056 is a BTL output - grounding either speaker lead won't do it much good.
