Ok, i am posting once again today, because of what has happened during the install of my system.

If you dont already know i drive a 92' 325i. In this vehicle there is an armrest. Where the armrest goes into is a sheet of metal (part of the back wall of the trunk). When they installed everything, it sounded like pure shit becuase of all the sound dampening material and the great job BMW did on sealing the trunk. Well, I decided to remove the sound dampening panel from the rear and cut a hole out where the armrest comes in flush with seat (getting pictures in 5 minutes).

Here is where i am having some thoughts. The hole looks pretty tacky when i pull down the little velcro flap that covers it (factory velcro..not sure why). anyways, i was thinking since this is my main port for the trunk to release the sound into, does anyone have any fabrication ideas to creating a sweet little plexiglass port?

I would like to throw down some neons around the plexiglass to give it some accent, but am wondering how my sound will be impacted. Wouldnt i have to figure out like the cubic ft of the trunk and all that crap?

anyone have any ideas or insight please let me know cause i am going to try and accomplish this and the amp rack over the weekend.

Thanks.

I say stay with the velcro flap. I'm not sure what you want with the plexiglass, could you be a little more specific as to how it relates to the hole?

Personally I would skip the plexiglass and neons.

The purpose of your hole, is to let sound come in. Plexiglass would just seal it back up. Even if you drilled several holes in it creating a faux grill would still impede sound. I would take some ABS and cut a frame that would fit in your hole. Wrap that in speaker mesh that can be found at any fabric store. Then using some industrial velcro, affix it to your new sound port.

Not super cool lookin, but very functional. IMO, neon doesn't belong on a BMW.

only if you are into extreme bass. I find my one 12 is plenty and then some.

So was I. Following my directions, you would be left with one giant port the size of the hole pictured. There is no reason to use plexiglass to shape it differently other than for asthetics.

TMac: Yes the sound dampening is good, but my little 8" sub is as much as I would ever need. And trust me, I listen to my music loud enough to hear every nuance...

In my old E30 I fastened a board to the back of that Ski hatch hole and a Phoenix Gold 12". It sounded well!!! B)

I now have an E46 and I am currently doing the same but only using a 10" this time.
