Has anyone here ever had any experience with larger subs like some 15's or even an 18 in the trunk of our car? Pictures would be awesome. I want to know what my limitations are dimensions wise, seeing as my irs $ is going to a new setup. i know that the volume is decent in the trunk, but getting it through that horribly narrowed opening is a pain.

 

I had a 15" in the EVO.... too much bass and the response of it was really slow. I had to put a 50ms delay on the full range speakers just to sync the highs to the lows. I then went back to stock on the EVO and put the amp and 12" in the ES, sounds much better. But as far as 15"s you can get 1 in there... thats it. And depending on the volume the speaker needs, you may be building the box in the trunk.
