Has anyone drilled a port into their trunk to help get the sound from a subwoofer into the front? I Just got a sub put in last weekend and you can tell the sub is really muffled from not having a sound port into the front. Has anyone done this? Is it possible?

 

I recall reading about people who have perforated their convertible top trays. If you search this forum you might find some threads that discuss this solution.

Another thought is to perforate or replace the trim panels that separate the trunk from the area underneath the convertible top tray. I will probably end up doing something like this.

Others, including me, have removed the convertible top tray. I know there are threads about this. If you're going to remove the tray, proceed with caution. The tray supports the convertible top when down. My own subjective impressions suggest it also masks out some road noise.

I'm also looking into removing the plastic trim that encases the rollbars. Again here, proceed with caution. Several other panels and, I believe, the rollbars themselves, have to be removed before the rollbar covers can be removed. If the rollbar covers are removed, won't the other trim pieces they were connected to (center glove box, side trim, etc..) lose some integrity? I still haven't found an answer to this question. Finally, there's the unsightliness of exposed rollbars and surrounding body metal to consider.

Sorry for the longwinded answer. Hope I have helped you in some way.

 

Yeah, since the search feature is broken, I eventually found this thread. I called up the guys that installed the system and asked them if they could make me some nice port holes into the trunk from the convertible top tray and throw some dynamat in the back to keep down on the noise. They said "Sure" and gave me a price. Then they warned me that cutting port holes and/or removing the convertible tray wasn't worth the money/work as it didn't do much more for the sound of the sub in the trunk. They've done quite a few S2000's and they said they used to cut holes in the convertible tray for the first couple of S2000's but they soon realized that this wasn't all that great of an idea.

Instead, they told me to just go with the dynamat in the trunk and let them kill all of the rattling from the tray and it would help boost the sound by at least 20% and keep down on the road noise from the back. So, I'm going in there tomorrow to get hooked up. Sure, dynamat is more weight on the car, but I'm not a racer. I enjoy my fast car, but I don't take it on the track.
