Yeah, this is why I don't want two 15s ported in there it totally eats your space up.
IMO 15% tint is the best

I was debating on 15, or 5, but 5 is pretty hard to see out at night.
eh, i had 5 on the rear window, 20 on the rear doors and 37.5 on the fronts and it looked just fine... depends on the tint used
i have a suntek guy w/lifetime warranty... smoke carbon, best lookin tint ive seen
I'll probably just get 15% all around.

The tint I got is Llumar High Performance, also with a lifetime warranty against color and bubbles.

May not have the output your looking for at the moment, but that box sure does look good since you wrapped it.
And I feel cutting out the rear deck will help alot. Ive done port back sub back, and sub up port up with the same setup (single SS RL-P 15"). Sub back port back seem to "boost" the lower end of the spectrum as expected with that configuration. However, sub up port up seem to have a bit more output into the cabin.
I think ill flip my 18" box up when I get my radio back in my car Tues or Weds.![]()

Yeah I gotta do something about the air being trapped in the trunk as well. I just can't figure out a way to do it without making it look bad. I want to keep my 2008 looking good and without ghetto cut holes. haha.
