So there I was, looking for a car that I could build this for that also had a double din opening for the H701 combo and that I thought I could fit the CD2 horns into. The GTi fit everything. After I bought her and made a trip up to my parents house to retrieve my IDQ15's, I made this hatch baffle in the parking lot of the military barracks I was living at with a single cordless drill, a jigsaw and some hand tools on the back of a friends old pickup truck! It only took a few days to put together. fairly simple!
