subwoofer

Can anyone tell me which stereo will come with the new A class amg executive a180d, and will it have a subwoofer in the boot, If not how would I go about adding one ,,,ie where If I have one is the amp... Thx in advance

Hi All, I was just wondering if anyone has fitted an aftermarket subwoofer and amp in an E Class Saloon 2002 or earlier? I want to get one but I am not sure if it will be a worthwhile exercise and whether it will be heard in the car as the fuel tank is in right behind the seats and also there...
