Do you know the frequency response of standart front door speakers for Fabia?

Dunno, but mine are really making the doorcards rattle and it's driving me round the bend!

Any advice other than take them to the dealer?

As a component system, at least with the one I had in my car with the Symphony headunit gives out from (audibly) 50Hz (Low SPL) to 16kHz.

Offtopic: mbval, in your signature it says that you have 112hp in your 1.4, what mods have been done to the engine? i expect that it was originally 100hp..

Yes it is 1.4 16v 101bhp but it is chipped and now got 112bhp
