The plate theyre talking about is the one behind the arm rest, and it has absolutely no structural significance.i'm worried about the barrier between the trunk and cabin as well. i'm going to be pushing quite a bit of power so i'm curious to how it's going to sound. i wouldn't recommend removing the plate.. that acts as a strut bar basically. i've seen modified rear decks to help air flow. only other thing i've considered is cutting a gap out of the plate where the arm rest is.
Our BMWs were designed to dampen the sound from the trunk. It will affect the sub. If you create a port you can have a much better and louder sound at a lower level.You don't need a "port" into the cabin. You know how you can hear the guy's bass from the car next to you? There's no "port" between the two vehicles! Lol
You will hear, and feel, it. No problem!
Maybe true, I won't say that it's not. However, I have single IDQ12 in a custom fiberglass box, powered by ~350 Alpine watts. It's very loud and sounds fantastic. In the past, I have had the ski pass removed (in fact, I've actually had the whole back seat out for spring cleaning) and I couldn't tell.TR4G-; said:...and louder sound at a lower level.
