Es una cuestión antigua pero creo que esto es lo que pasa y la solución:

QUOTE
This is exactly what happens when you plug an mvs into a standard jamma cab. It tries to output stereo onto mono wiring. In other words the stereo amp's both outputs go into the negative and positive terminals of the speakers, thus being forced to work against each other without a proper ground connection instead of both positive outputs going to separate speakers with a completely separate ground line. This is -bad- for your amp in the long run. It is like turning on your stereo, only to use both positive outputs of the left and right side to drive a single speaker. A decent stereo actually activates a protection circuit in such a case.

What you have to do if your cab has 2 speakers:

1. open your speaker compartment, both speakers should be wired in either series or parallel.
2. Run a single wire from the pcb connector ground up to your speaker compartment
3. Disconnect both speakers
4. at this point you should have 3 wires in your speaker compartment the 2 that were already installed and a new one.
5. connect new wire to the negative terminals of both speakers
6. connect the factory wires to the positive terminals.
7. do a sound check, you may need to reverse which positive wire goes to which speaker to get the left and right side correct.
