Please help me out...
The problem is that on the back of my amp head there are 2 inputs for EACH the right and left. However, they are only labeled right and left, no ohms or anything. (See attachment "Back", thats not an actual pic of the back of my head since i dont have a camera, but thats how the layout basically is)
My guitar cab has the inputs which are labeled. (See attachment "back of cab"). I want to wire my head in stereo at 8 ohms. I know where and how to hook up the speaker cables to the back of the cab. But i am not sure how to hook it up to the amp head since its not labeled. I am reluctant to try anything because I dont want to mismatch ohms since i heard that can be damaging to the amp and/or cab.
Please, anyone could you try to help me or offer me advice. If you need any more clarification just ask. Also, i kinda need an answer ASAP, im suppose to jam with some friends soon and wont be able to without this head/cab setup.
Thanks.

From what I can tell, it would be like this, LEFT 4\8 - RIGHT 4\8.

Alright, thanks man I hope you're right.
Just wondering though, worst case scenario what could happen if i plugged in the speaker cable into the 4 ohm input on the head into the 8ohm input on the speaker cab?
and how about 8 ohm input on the head into the 4 ohm input on the speaker cab?
Which one is worst? I think the 8 ohms into the 4 ohm cab, right?

In addition to my previous questions, would matching ohms matter since my head is a solid state head and NOT a tube head?

Its a hybrid amp, you have tubes in the powersection, its guna matter.

Nah man. The amp is all solid state. The pic of the back of the head is not actually my amp. I just used it since the layout of it is just like my head...and because i dont have a digital camera.

if its the one you posted in your signature... the outputs are
"Dual left/right 4/8 ohm external speaker outs"
set your cab to stereo 8 ohms, and plug both the amp outputs into the cab... it should be fine.

Yea, i have the Randall RH200SC, not the G2 version. Its the original version which i believe is now discontinued.
But anyways, thanks for the help guys.
Just curious, when i use the stereo option for my ONE cab does that mean its wired in series or parallel?
Because i remember reading somewhere that when hooking up a cab or cabs in parallel the ohms of one cab is divided in half. For example if i was to hook up my head to 2 cabs in parallel, each cab with an impedance of 8 ohms, it would really be 4 ohms. And thus the head must be 4 ohms.
Because if my cab is in parallel then that means i would have to plug it into the 4 ohm input on my head to prevent it from burning out. But if its wired in series, which i think it is, i can plug the cab in stereo into the 8 ohm input on the head to achieve maximum power.
So am i worrying about nothing here or is this gonna be an issue?
Sorry for all the questions, but I'm kinda new to this whole thing.
