Hello! I'm wondering if anybody did this to his Alfa. I saw a video in YT **https://youtu.be/o9S7hwud7Og**, and at 1:11 you can see this guy have an MP3 Player installed at the driver legs. I want to install a subwoofer, I have it already, with the Radio MP3 Player and the amplifier, now, how to install them. I don't have the Bose sound system on my car. I saw a lot of the dudes installing this kind of setup, but not on Alfas. I want to do something good, and I can't find something clear on internet. Can somebody help me?
