I was kind of scheming to install a powered sub in the trunk of my coupe, say an 8" Bazooka or one of several newer compact subs on the market these days, something easy to remove because coupe trunk is small.
Then I remembered, past cars I have owned that were near-luxury, they all seemed to be very effective at cutting the strength of the subs in the trunk. To the point of being nearly "not worth it".
Does the G37 coupe also kill the bass of subs in the trunk? As in, is it even "worth it" to use something as weak as compact sub when the stock Bose is already fairly good?
That's a great question and you're right that these cars will have sound deadening to prevent road noise from entering the cabin from the trunk.
What are you trying to accomplish? For me, I like the sound of the stock system and will add a 12" sub to enhance the low end as this system bottoms out around 35 Hz. While much of the output from the sub will be restricted, the impact to frequencies below 40 Hz won't be as noticable and the impact to the low end should be enough to overpower the stock system.
However, if you're going for SPL then you'll need to take measures to minimize restrictions from the factory sound deadening such as removing the carpeting from the trunk panels and under parcel shelf, remove factory sub to allow airflow, etc.
Hey F13, I saw your thread on your install, very nice!
That's what I used to do "back in the day". These days, factory systems are much better, and as a married family man, I can't justify spending the effort for a nice install like you.
Was listening to Wu Tang yesterday, may not be worth it to just install a compact powered sub. Stock Bose does ok. I remembered why I noticed some cars cut bass. Back in the day, back seats had an open back to the trunk. When fold down seats arrived, they required a metal backing and usually also covered in carpet so items could be on them whilst folded down. This greatly reduced how well the bass comes through. Overcome it with volume, power, speakers and/or venting the trunk space into the cabin.
So, yeah, to answer my own question, I would likely be disappointed in the results of a compact powered sub. A 370z would likely do very well with a compact powered sub (obviously).
Forgot to mention, my "trick" back in the day was to put the top seat latches on spacers so when the back seat was up, theredt be a gap to allow the bass into the cabin. It works well. Also tried to make sure the install didn't create a wall between the trunk space and cabin, I would leave gaps around the enclosure and trim to allow the bass to travel around the equipment and into the cabin.

My panel does have small vent on each side just for that, Need to work on a small spacer for latch soon.
There is a 4080 corner box on the classifieds for a good price including a nice JL sub. I have that box with a skar vvx-3 10 inch sub powered by a small fosgate sub amp and it will literally shake the car. Highly recommend it if you need to conserve some of the limited trunk space.
Anyone know where I can buy one of these? Finding a used one will be a pain in the *** as I'm in Canada no where near the border and would prefer to not get one custom made.
