ive got a CGM 4x12 that is 8 ohms. i want to rewire it to 4 ohms because my amp is a 60 watt 4ohm head. i dont care if it gets much louder, i just dont want my precious amp to burn out. if anyone could give me some advice on how to rewire this bitch that would be cool. also if you dudes dont think it will **** up my amp tell me and ill leave the **** alone. i really like this cab cus it sounds so deep and dark like no other cab thats why i dont wanna trade
You can't wire it to 4 ohms.

You have four 8 ohm speakers, two are wired in series for 16 ohms and those two are put into parallel for 8 total ohms. The only way you could wire a 4x12 to 4 ohms is with a quad of 16 ohm speakers.

What kind of head is this? If it's a solid state head then don't worry about going over 4 ohms. I've personally never heard of a tube amp with a single impedance option at 4 ohms, it's almost always wired internally to 16 ohms or otherwise, it is switchable to 8 ohm and 4 ohm taps. Even with a tube amp mismatching up will generally not have any ill effects outside of bad tone.

edit: Since this should be posted in GG&A, I'll copy this over and answer any more questions in your thread there.

The head is SS so it wont blow up running 8 ohms. It will cut the available power. They usually run SS at 4 ohms as its cheaper. Tube amp have the OT so the power doesnt drop with different ohm loads. As long as your happy with the volume then should be ok. But if comes to a point when you have the volume maxed but need more volume then you would need to find a 4 ohm cab.
