Where is radio (aerial) amplifier located in Superb? Or is there one?

I changed Symphony Radio and now there is some problems how radio sounds.

You need a booster, be careful which one you buy though, I got one in Halfords, cost £14 and it was worse than using without.

I read that if you replace original radio in VAG-car, you need to get amplifier so the radio works afterward. And I can tell you that it's true.
