I decided to try using 8" sonotube for ports for my pair of Credence 15's. The problem i have is really annoying:
Now and then i need to use my back seat, so in order to fit my subs and still use the back seat i need to have a removable port, or at least part of the port.
I was wondering if anyone knew any ways to attach 2 pieces of sonotube together. That way i could run a shorter port while the seat is being used and pop the ends back on when i dont use the seat. It's really annoying to have to do this for one day out of the week use of the back seat. Oh well.
