Hello Volvo driver, I wanted to install a bass box in my XC 70! Now my problem is that I don’t really know where to start.. I once read that it’s versions with original built amplifiers and subwoofers, is that right? Should there be somewhere in the trunk (I looked inside but couldn’t find anything, just a DVD player) Now I just don’t know what my radio is called (if you want to know that) I have a picture attached to what my interior/radio looks like (except that I don’t have anything in beige!) Can someone help me where I can connect the box with the subwoofer and amplifier? (will probably be a custom box) Technically I’m not quite unsolicited, so I should get that! I hope you could give me a lot of good tips?! First of all thanks.. MfG Clemenss
