Welcome to the forum. You're wanting an 18" in the trunk? Those seats don't fold down so it's a little tricky to get the air INTO the cabin.

Thanks thought i join one been doing car audio for a long time now. Yeah these trunks are tricky. I took my backseat out and cut the metal behind it for more airflow.

Why not just wall it, then?

I really want to been doing alot of thinking about that lately. Looking into the 21" warden if i do, or gonna do a 4th order with the AA. Id like to do that and have my backseat in and put the port through the armrest. I wanna mold some 6.5s around my car so thats why id like to do the 4th order in the trunk.
