Hi guys, 

I am exploring the possibility of performing an upgrade of the stock front/rear speakers for my RS and replace them for a custom Focal Inside premium 8.1 set. My question is ... do you know which is the diameter of the door support? I assume that the front and rear should be the same. Octavia mk IV is not listed in the Focal web as compatible model but the closest one in the range is the golf VIII with 158 mm diameter between supporting points (2 way component kit IS VW 155). I guess that for the Skoda should be more or less the same dimension. Let's see if somebody could help, if not, no choice, I will dismount the door trim panels to take a look.

Cheers!

It should be the exact same as the Golf, 168 mm woofers stock, but who knows what kind of aftermarket ones might fit, because they have different mountings and bigger magnets usually.

Those from Focal are sold as plug and play ... in the installation videos they have in their web for the Golf VIII installation, audio connectors, mounting points and woofer geometry fit the stock so I would say the set would fit. It's a pity that I cannot check in partslink24, but I would not be surprise if the Golf and the Octavia share the same part number for the speakers.

I'd be interested to know if anyone finds out for sure. I have older ears though, so I don't really need high volume, I need high quality!
