Creative subwoofer install

[Luis A.]

Searching the web for ideas on speaker installs for the E3 I found this install on an E9 (love the color... ) for rear seat divider subwoofer. Very discreet and I bet it pumps out pretty good sound.

nice

those guys do really nice work, and get paid VERY well - ive seen stereo installs in that shop, in a brand new suv, that cost more than the suv.

sub install in the back armrest is clever, but i love the way the factory arm rest folds down, plus not sure the subs would sound all that good there, not a very big box to resonate in.

also kick panels, while nicely done, still look hokey.

my kick panel and sub pics below - no holes cut, and subs below back seat, REALLY put out.

I am working on a version of what Alan has done, with the 4" Focal K2 speaker in the kick panel, but moving the tweeter to the ash tray with perf metal replacing the vinyl.

My coupe has a pair of 6" (if i remember correctly) speakers below the rear seat. My thought is to use a 6" (or 2) sub under the seat ... or a flat 8" sub and turn the current speakers into ports for the sub.

Alan, how is the sub installed under the rear seat without cutting any holes? Looks like the speaker cone would just be facing into the sheetmetal.

ha, should have clarified, no 'new' holes. po had drilled holes in the sheet metal for speakers already.
