Is it possible to use some sort of Y cable from both the Speaker Output and the Extension Speaker Output into a single input 4 ohm cabinet?
See the problem is I have a 1x12 Galaxie Combo, and I would like to try my Galaxie through the Z 4x10.
Thanks for you help.

It sounds like you're going to bypass the combo 12 and only use the 4x10 cab. The following recommendations apply to running ONLY the 4x10 load. 1) Galaxie master T-Rock uses the Weber impendence matching device with great results. 2) I've read that the Gal can handle a 4 ohm load from one of the 8 ohm outputs (if the 2 8 ohm outputs are tied this would make sense but I've not seen that posted in the Gal pages so it's a use at your own risk... I'm a weenie and would only do so if Z says it's OK. I've run a 4 ohm load for short periods of time and didn't notice the output trannie overheating but I don't recommend it... I should probably have lace applied to my underpants. 3) Add an additional speaker jack to the Dr Z 4x10 cab and run 2 of the speakers in series then do this for the other two speakers. Use 8 ohm output jack for one of the 2x10s and the 8 ohm extention speaker output for the other 2 10s. The second output jack can be mounted to a wall in the cab so no holes are drilled in the cab. 4) wire all 4 speakers in series for a 16 opm load. This is what I did and it sounded great. I do think it's best to match the output and loads. I didn't gig with this set up so I don't how it would sound with a full band but I cranked the Gal and it sounded great.

Mike may come along and correct me, but I would say NO, never on both outputs to the same load.
If you want to run your 4-10 with your Galaxie, and it is a 4 Ohm cabinet, you can rewire the speakers inside the box to either an 8 0hm or 16 Ohm load, as Drew is saying, depending on exactly what is inside. So, what is inside the box and how is it wired?
I have to run out for a while, but I can post some links to some of Mike's posts about such things when I return.

I'm guessing if it's a 4 ohm cab that you've got 4 16 ohm speakers all in parallel? If you parallel 2 and parallel the other 2 seperately (8 &8) and then series the 2 pairs together you got 16. I'm not seeing 8 ohms using all 4 but maybe they're not 16's?

Yes, I would not be using the 12 of the combo at all. Just the 4x10 cab. The 4x10 is stock, and is 4, 16 ohm speakers wired in parallel with a 4 ohm total load. I do like the idea of running two (wired parallel for 8ohm) with two separate jacks into each of the speaker outs on the amp. That sounds like the easiest for trial purposes. Glad I didn't solder them tight yet!
Thanks to all of you for your help. I would like to hear more.

Your not saying your plugging into two different taps in the back of the amp are ya? Not advisable. Now if you were doing the cab for the 2-8's so you have the option of a 210 setup into your 8 ohm tap or the 2 8's into a parallel splitter cord plugged into your amps 16 tap. I have a feeling that's notwhat you meant though.

Am I an idiot or what. Should have looked before I spoke. I see via Bentops amp chart that the Galaxie only has a single 8 ohm tap with no other choices. The only way that comes to mind now to get 8 with 4 10's is if you had four 8's wired in parallel pairs with those two pairs in series. I think someone like Weber makes something that compensates for such problems but I'm not the sharpest knife in the drawer

You're only trying to provide good advice, no foul there.
