Installing the External Crossovers in the 4343 (continued)
- Remove LF and MF drivers.
- Remove Upper Baffle. Disconnect HF and UHF drivers. Pull MF wires out of MF box.
- Label all wires. Recommend taping off or placing shrink tubing over these abandoned wire ends to avoid any future mishaps. Coil up the old wires and secure with a tie wrap

- Prepare your 5-3/8" x 6.5" wood or plexiglass panels to replace the rear input teminal plates by drilling a 1-3/16” hole for the male Speakon connector and pilot holes for the screws. Alternatively you could leave the rear input terminal plate in place and drill a 1-3/16” hole in the speaker cabinet for the Speakon connector. I opted to replace the plate so that the speaker could be returned to stock condition and to retain the value of the speaker.
- Remove rear input terminal plate. Route it out of the way and in a place that will be rattle free. I wedged it into the upper left hand corner of the speaker and covered it with fiberglass.

- Install your wood or plexiglass panels which replace the rear input terminal plates. If your panel is less than 3/8” thick, you can re-use the original bolts. Regardless if you use the original bolts or not, you will need new nuts as the nuts on the original rear input terminal plate were pressed into the fiberboard and cannot be removed.

- Install front-to-rear brace. My brace ties the top of the rear center 1x4 upright brace to the front baffle. Where it ties into the front baffle it is offset to the left approximately 1” from center to provide clearance for the lower center baffle bolt and avoid interfering with the stock L-Pads. I made very sure before gluing and screwing that this bracing would not interfere with the L-pads. I’m sure there are other and maybe better ways to provide additional bracing in the 4343 cabinet so I won’t go into more detail here other than I did cover the new braces in fiberglass.
