Hi does anyone know the size of the front and rear speakers in the octavia vrs? as i want to upgrade as the standard speakers are s@@t

I've replaced my fronts with 17cm alpines x type (?) and the rears with 13 cm Edge 305. The sound quality is magnificent

Just bear in mind that the fronts either require some metal cutting, or slim fit speakers.

Have a look in the ICE section of Briskoda, as this subject has been brought up loads of times

They're 6.5" IIRC. As mentioned above you need quite shallow ones:

I'm also thinking about this. If I do replace them, will it render all 4 tweeters redundant?

Does anyone know of anywhere that do the wiring adaptors as I have better rears sitting in a box but dont want to cut the standard connectors (they use three wires at the moment?)

I brought some wiring adapters on ebay, and they were wrong :(
