Gday deNs, very close to installing a parcel tray where my back seats are and I really want to attach a sub also. Just thinking, how did you attach your tray and sub so they dont move and bouce when you drive?
I'll grab you some pics soon, though i've wanted to hold off until it's finished before posting pics.
Essentially what my sub is, is a QMAX Invisibass 6. It's a 6.5" sub in a Ported and carpteted enclosure. It's got a wooden frame around it with neoprene padding so it doesn't transmit vibrations too much, and is held firmly between that and the top panel, which also has neoprene on it.
I can draw up a cad drawing pretty quick so i'll do that in a short while if i've got time.
Also, you could've just posted the question in the thread with all the progress
