When we had to sell our new scirocco after only having the soundsystem we paid 3 grand gprs upgrade to.
Thankfully, when we procured our new mk2 which we spent a while finding, the guy failed to put on the post that it also had a full alpine soundsystem in, including a 12" sub, 2" bigger than the one we had in the rocco.
Turned out pretty sweet. You will hear me before you see me.
