I currently have one SR124dvc and will be adding another. I have the sub facing the cab. I know car audio is a try it to see if it's better but I'm wondering if it would be worth the effort. My question: I have a large rear deck in my seabring and Iím thinking about fire the subs up towards the rear window through the 6x9 holes. The rear seat is very thick and that's one of reasons I'm thinking about doing this. I would probably build a wall behind the seat to deaden the sound from the trunk. Also I would place the subs as close to the rear deck as I can.
