I have a 4ohm z-best cabinet that I use with my Rt66. I would like to use it with a few other heads, but I would have to re-wire it to be 16 ohms. Is there any reason that I should not do this? Thanks for your input.

Do you know if those other heads have 4 ohm output jacks?
for you to have a 4 ohm Zbest....it's got to have two 8 ohm speakers wired in parallel. And you're considering wiring them in series to make a 16 ohm cabint. It's a little bit of a different sound to wire them in series. Most people won't notice the difference. but to answer your question, there is no reason why you can't do it.
You probably weren't looking for this, but you might consider getting two 16ohm speakers and wire them in parallel. That way it will be an 8 ohm cabinet. Lots of options if you do that. Every amp accepts 8 ohm cabinets.

I don't want to change the speakers, but I guess that is what I was asking. What would be the sonic difference when using it with my RT 66 if I did change the cab from 4ohm to 16ohm.
The head I want to use it with for small gigs only has an 8 and 16 ohm tap.

I can't remember what the tonal difference is. But I do remember it's not much. I usually use single speaker (10 or 12 inch) cabinets.
But when I have used 2x12's in the past, they've always been wired in parallel. Even my old Z-best. I had loaded with greenbacks. (that would go well with a route 66....and I had one of those too)
Maybe someone else can state the tonal difference.

I think it may be a moot point! lol I just tried to pull the back off, so could try it for myself. The thing is stuck in there like glue!!

Typically series wiring gives you a slight delay between when the speakers get power to them. This can sound a little fatter or little mushier depending on who hears it. Conversely, parallel wiring can be a little punchier sounding. In either case, the difference can be subtle depending on your ears. There isnt really any harm trying it and see how you like it. My 2 cents, Todd

I think that if the speakers are in series and they are the same speaker then you shouldn't have any noticeable change.
If you have two different speakers such as a gold and blue then that might have a tonal difference and that is why some would utilize that wiring.

I typically like a little "saggier" tone so I might prefer it as a 16 ohm cab, but I can't get the back off. I have tried removing the corners, taking the jack out so I could pull in the hole, tapping the side with a rubber mallet, and threading a screw in part way and pulling on that. It won't budge. Any other suggestions on getting the back off?

Any other suggestions on getting the back off? I had this happen on a brand new Laney cab once. I had to use a pry bar to get the leverage and pop it out. it did the job with no damage to the cab. I tried the "screw half way out and pull like hell thing", and it didn't work either. Try a pry bar

You say you've tried tapping the sides but what about the edges of the back itself?
I've had success like this before with a small plastic (clear hard yellowish nylon?) mallet that I use mostly for gunsmithing. It actually has rubber on the opposite side of the head but use the plastic/nylon side and tap the edges of the back all around where the screw hols are. Don't hit it hard enough to mar the tolex but give it a series of pretty good raps just up to that point. This will usually work.
If the above fails you might try heat from a hair dryer then repeat the above procedure. Don't use a heat gun though, and don't ask me how I learned this!

I win!! Lol. But seriously, thanks for your help. I ended up getting it off with minimal marring using a small pry bar and a rubber mallet. I have to be honest though. The sound it made breaking the seal, sounded like I was pulling nails out. I have never had a cabinet that stubborn.
