Hello, does anyone know what size arte the speakers in octavia 2008? I realy need to replace them.

17cm front and rear door drivers, plus separate tweeters.

 

Google search and you will find loads of kits and info.

 

A lot come with replacement adapter rings as the originals are riveted in so need to be drilled out. If your new speakers don't come with adapters you'll need to buy some,  you will also need wiring harness adapters to connect to the existing loom unless you are running new speaker cable from an amp or similar.

 

All of these bits can easily be found on eBay and other sites.

Rear replacement vid here if you need:

 

 

 

Shows the adapters for wiring and mounting the speakers to the door cards. Think from memory rears are 16cm - 16.5cm.
