I want to run my Powerhouse 1000 (4x10+1-15) in stereo. It has two 8 ohm jacks. 1 8 ohm for the 4-10s, 1 8 ohm for the 15. Also one for all of them combined 4 ohms. I am getting a G-K 800RB for cheap, and want to run it into the 8 ohm 15 alone, then run my Mesa 400+ into the 4x10s with the other separate input. BTW, the 4 10 have a deeper bass sound than the 15. This way I can get that quick GK growl and the vintage tube sound in the same cab. Crazy????
