Okay, heres the deal.

I've got two 45 watt Marshall MG amps (A CDR and a FX)

Is there anyway of linking them together to get a 90 watt amp?

Or something along the lines of that so that I can use both amps at the same time?
Doesn't work that way. And you can hook both amps depending on the amp with an audio cable from the output of one to the input of the other.

And I totally read "Licking amps" when I saw this >_>
Two MGs?!?! Imagine the CRUSHING overdrive!

lol, well technically you could, just get an A/B/Y box and you'd have around 300 watts of volume maybe (something like that). i'd sell both of them and get a good amp though

Head and Cab for $130? You don't need a head and cabinet, you need a psychological examination.
