Ok. I have the Rockford Fosgate Pl2-212 sub system with a Power Acoustik lt980 amp. I have it bridged and it hits hard. I was wondering if i should sell it to my friend for 400 and get a aw1506t with a8000t amp or get a refurbished Kicker l7 15 with a8000t amp or if i should just keep my current system.
