best box for a trunk car without fold down seats, but has an armrest.

4th order or a ported box facing the rear? The car is a Cadillac brougham it has a big trunk I'm 6'3" and I can get inside and lay down. The thing is I don't want to take up the whole trunk. Have any of you ever seen or built a box for this size trunk?

If it were me and I had the space, time and patience, Id do a 4th order ported through the rear deck.

if you put a ported box in the trunk, it will create a 6th order.

My trunk is set up same way and I tried ported and 4th order. Ported seems to work best in my application.

I would try the forth ported through the rear deck but the deck is filled with 6x9's and 6.5's components with tweets in the middle of the two.

@loudbimmer how did you port through the armrest?

[LoudBimmer]

I used 8" PVC port

What are your goals with this setup?

[SICKSPD]

Why would it need to be ported into the rear deck and not just sealed off with the port firing forward?
