Subwoofer in the trunk
 

Hi guys,

I own a 940 2.0 Turbo SW of 1997 and I wonder if anybody in this forum has ever tried to put a shallow mount subwoofer in the under-trunk.

I want to install a subwoofer but I do not want to compromise with the loading space, so it has to go down there.

So far, I saw that Pioneer manufactures a spare wheel subwoofer but I have no idea how it works and I am a bit suspicious because no other manufacturer really followed that path.

Alternatively, shallow mount subs can be found, under 4", but I am not sure if the thickness of the hatch (half inch) is enough to keep that weight and/or prevent any vibration.

That is why I am looking for somebody who has attempted this before me :)

Thank you!
Alex

My 740 estate has a small pioneer subwoofer mounted in the spare wheel. Sounds great :)

My brother's 940 has a spare wheel well which is a different shape so you may not be able to have the wheel facing down like I can.

Can you verify if your sub is this one?

I have to verify if there is a way I can still fix the spare wheel even if it is flipped the other side.

I forgot another question, you can simply close the hatch without worrying to drill a hole in it for the bass to sound properly?

I've got a TS-WX210A in mine, which I mounted to a board that fits in the spare wheel. As bass noises are directional, being under the hatch (and behind the rear seat and below the luggage cover) doesn't seem to have a significant influence on the sound quality. I often have a few bags in the boot and can't say I've noticed any difference.

I've also uprated my door speakers (same size as OE) which helps a bit too :)

I verified if the spare tire can be flipped, in theory it can but it is not engineered to be in that position, it has to stay as in the above picture to be stable in its location.
Given that the spare tire is not an option, I checked the two side storage spaces:

I think it could be a possibility, but I could not find a manufacturer of elliptical woofers, I think I have seen one some time ago but who knows whether it is good/bad stuff.

Could you not make a fibreglass mould out of the bottom section then make a box up top? Then use a shallow mount 8 inch sub?

Probably I could, but if I can find a 12x8" of decent quality even better.
Let's see what I can find on the internet.
