Stereo power amp + parallel cab question
So I have decided to go a little weird with my rig. Basically I am splitting my signal into 2 paths running 1 through some effects pedals then my laptop (via audio interface) then into 1 side of a stereo power amp. the 2nd channel running through a meatsmoke pre-amp then to the other input of the power amp. From the power amp I want to drive 2 cabs, 1 from each of the 2 outputs with independent signals. Just a little unsure if this set up will halve the Ohms of resistance as with other parallel cab setups. I am assuming not but want to make sure before I fork out the money for a power amp that could potentially be way more powerful than I need.
