just joined up to this site, but am part of other forums. i drive an 05 nissan altima 2.5. i currently have 2 skar vvx12s in a 4cf box port tuned to 32hz. with an ap1500d at 1 ohm powering them. just recently had to go back to stock components, so thats what ill be upgrading next (again lol). im really considering the tantric hd components which is why i signed up here!
