Has anyone had a custom sub box made for the back of the zx3 that doesn't take the function away from the back area (trunk?). I have seen the SVT sub but 8" sub just isnt going to cut it. I would like at least a 10". Has anyone made or had someone make a custom sub box that mounts in the rear right or left panel of the car? I dont want anything flashy, more like something that can blend in and look almost stock. Any suggestions comments would be much appreciated.
