What is the ACTUAL wattage on a Kustom K250 with all the bells and whistles? Also, can the be used with TWO 4x12's? Also, has anyone tried one out with a cab with Celestions? If so, how different was it? Thanks!

Hi. If you do a search here you can find a posting I did about 2 years ago when I tested the output of Kustom heads, but I will save you the trouble!
Your fully loaded K250 outputs its max wattage with a 4 ohm load, which will be 110 watts RMS. If it was the non-effect version it would pump out 117 watts RMS, are barely noticable change.
Into a 8 ohm load the wattage drops a fair amount, down to 81 watts RMS.Not too bad as compared to some other brand SS amps when you double the load impeadance!
Most 4 -12 cabs are 8 or 16 ohms. so either could be hook up to the amp with a Y cord made for speaker use( a regular Y cable made for line level signal will not last too long under speaker amperage drive)
The two 8 ohm cabs in use with Y cord(parallel) would place a 4 ohm load on the amp, 2 16 ohm cabs would be a 8 ohm load thru the same Y cord.
Some cabs have a switch to take it from 16 ohms to 8 ohms, but you did not state what you have.
Dependant on what the impeadance of the drivers are in the cabs in question you may be able to rewire them to get a different total cab impeadance.
For example, a 16 ohm cab with out a load switch, loaded with 4 8 ohm drivers can be rewire to be a 8 ohm cabinet.
I have played K250s and many other model Kustoms thru Celestion speakers and they sound great, at least to me.
The K250 has a wide frequency control range normally, and even more so if you use a short cord to jump your guitar into both channels.
The amp, or any amp will sound different tonally thru the same speakers when they are wired different as the not only changes the impeadance, but it changes the inductance load also which has a fair effect on tone.
More indutance will make for less chimmy highs and mellower bass.
One things for sure two 4-12 cabs wired for a 4 ohm load on that K250 head will make for a LOUD amp.
