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.

You will definitely need to cut out a the board from the boot following the outline of the back seat arm rest. And drive the rear arm rest down for maximum results. A good installer will seal it in a way that you cant see into the boot and there will be no material flapping around with the air pressure. It should basically be a stealth install and mod.

Thanks bud
I was thinking of going with 2 x 12” powerbass subs and doing some sound deadening sheets for the rattling
But I will try the ski pass and consider the underseat woofers aswell

Thanks for tips bud
