Hi there guys,
I was talking to a mate today (owns a black lupo), and he said he wanted to uprate his sound system with some rear speakers to give some bass, but his parcel shelf isn't big enough for 6x9s. After a quick look around the car the only way I could think of mounting any 6x9s would be on a raised boot platform made of mdf. He isn't interested in buying a sub so just a box is out of the question

I was just looking for any input you guys might have, since I can't think of any other way of doing it

Thanks
