Discovered that my right side focal is not working. I'm trying to figure what model it is...but can't find anything. Can someone help me? The reference number is 6K4441/R and the serial number is 0003389. Man, this sucks....they came with the car and they sounded really good.

 

Focals usually say what they are on the magnet, take a pic and post it.

 

Not sure if it's worth checking mate - I just fitted a set of Focal A165's and the right channel just went dead after 2 days. Thought I'd blown it.

Turned out to be a loose connection when I was fitting the Alpine HU.
One of the speaker wires in the stock block just started playing up (All it needs is a good old bump in the road)
Takes a lot to blow a focal, try checking the connections mate.
Or take out the speaker and switch it with the left hand one. See if it fires up.

 

I checked if the speaker worked directly from the amp. I will check again though. I emailed focal and have not received a response.
