Hi all,

My car is a Volvo 940 2.0L SW, few days ago I purchased a new radio receiver, a Pioneer AVH-3400NEX which is working fine.

Now, I want to change all the existing speakers (20 years old) and add a sub, the challenge is to preserve the loading space intact and use, possibly, the under-trunk space.
Some pictures should help.

The space you see in the second picture right under the 4 screw holes which were holding my old CD Changer, it is 4" high, therefore I was thinking to a shallow mount sub in that position.

The spare tire is not an option as it cannot be flipped the other side, it has to be fixed the way you see in the picture.

I do have deeper space on the sides (see pictures below) but I would need elliptical subwoofers and there is not much on the market, actually only one brand.
