I did the same thing over the weekend and found my favorite, the bottom right. I also opened up the back of the cab and tightened the baffle board screws with a screw gun set to tension 9 and it was amazing how much some of those screws moved before the clutch gave way. I also replaced the thin transistor speaker wire for 12 AWG wire. The problem I ran into was trying to get two strands of 12 AWG wire to fit into the 1/4" jack. So I spliced the two wires together and at the other end of the butt splice I put only one wire lead. Then I drilled out the holes on the jack to fit and bingo! I also caulked the baffle board to the sides of the cab to seal things up nicely. Low mids are more defined now and the cab is super tight sounding,......... enjoy.
P.S. I like the bottom right, sorry for the slight hijack.
