Port and Sub direction: well insulated trunk

[UCbizerkeley 10+ year member]

So I drive a 735i that has great insulation between the trunk and the amp. I'm building a box for my two R's and need to know which direction to fire the sub and port. At one point I had a single R in a sealed box and it honestly was negligible.

I am honestly thinking about just firing the subs and port directly at the backseat.

Opinions?

I don't know which year your 7 series is, but have you tried removing stock speakers in the rear deck? they allow for more bass to enter the cabin

btw what amp are you using?

Most trunk cars are recommened to aim and port toward the tailights. But than its not for all cars. I agree with removing the stock speakers in the rear deck.

Remove stock speakers for more direct flow of bass into the car?
