Steve,
I remove the backs for a couple of reasons. To see that there are no objects that may have been stuffed through the port tubes. I like to check to make sure the cabinet has the correct speakers, and to make sure all the nuts that hold both the speakers and the baffle board are tight.

I personally like to remove all the speakers and port tubes, pull the baffle board out of the box and take it to the car wash. Power wash/rinse and vacuum off the excess water and let it set for a couple of hours before I start to re assemble. Cleans all the stains and dust from behind the grill and dust on the speaker openings. That's just me. Brings the grill cloth back to showroom condition. Some guys use simple green with a tooth brush to clean the grill.

Kustom used 16 ohm speakers wired in parallel, so the three speakers presents a 5.33 ohm load to the amp head. The K200 amp heads runs 100 watts into a 4 ohm load.

I wouldn't use 8 ohm speakers since it would place a 2.6 ohm load to a 4 ohm amp. You can always run above the 4 ohm amp but going below can damage the amp.

I'm not sure how big of a guy you are, but that cab with the added weight of JBL's or Black Widows would break my back. The Jensen's are the guitar version. CTS would have been for bass.
