Thank you for reading my post. I am a 20 year veteran of car audio system building, though my involvement has drastically decreased since becoming a Dad. It's time to install a system in my 2012 Scion xB. I have a Rockford Fosgate T1001-bdcp amp that does ~750 watts @4 ohms or ~1100 @ 2/1 ohms. Most importantly, I am an old school basshead who still listens to real bass music from the early 90s (Techmaster P.E.B., DJ Magic Mike, Bass Patrol, etc.). My bass CD collection is a source of pride for me. Anyway....I am looking for a single 12" or 15" woofer that will give me the 20-25 Hz notes that I crave. My maximum external dimensions are something like 22" wide, 17" high and 17" deep. The Icon 12D1 (in series) looks to be my best bet thus far. I'm trying to preserve a bit of trunk space for groceries and such. Any suggestions are appreciated. Happy Thanksgiving to one and all.....Joey
