Hello Just got my golf back after having it fixed and looking to do the speakers. I've got the factory fitted components in the back and in the front. I've read up on the pitfalls (speaker surrounds and such like) of upgrading the speakers but feeling a little brave. What I would like to know is that if I get two pairs of Hertz Dieci DSk 165how do I set up of the crossovers properly. I have been told that VW originally used a simple ballast to split the frequencies and since my Golf is 18yrs old feel that a modern crossover would be a tad better. I need to know where to physically put them (especially for the rear set) and how to do the wiring. Also how do you get at the rear speakers properly? I'm guessing you have to remove the cards or do can you do it with the help of a small child with nimble fingers? Much appreciated if any ICE installers out there can assist. Dougal.
