discussion E90 320d subwoofers in boot?

[Josh]

Howzit guys
So I have a e90 320d with the non folding seat and the metal backing… I wanted to put in subwoofers but I’m not sure if the sound will be dampened by the metal backing as I have a exhaust system but I hardly hear it from inside the vehicle
Any thoughts?

Hey bud,

The sealed boot does dampen the bass significantly. You will need to either cut the ski pass or port the back board.

Your post mentioned subwoofers...more than 1 should sound decent, but you can expect alot of rattles with that setup.

I'd consider upgrading the underseat woofers, if cutting the ski pass isnt a road you want to go down.
