I'm new to this forum but have been a long time follower and sub to Meade916. I want to do an Infinite baffle build from the current system I have but am unsure if I want to add a 3rd 12 inch sub. The build is as follows in a 2012 Hyundai Elantra: 2 B2 Audio Rampage 12D1's on 2 Crescendo Audio Bassclef 4k amps strapped with audio batteries back there as well. I know I want the motors facing the rear with the cones aiming towards the front. Should I add a 3rd or just build it with the setup I currently have now?
