I think you just replied to yourself!
No, but unless it's a dual voice coil speaker you really shouldn't run a 4ohm speaker from an 8ohm receiver. The amplifier will overwork and
eventually give out. I don't know how long that may take, but it will happen.
My advice is exactly what your last post said.
Run the sub from a separate power supply and just source the audio signal in.
If you could "bridge" the output of the receiver to 4ohms, then yes you could run it.
But that would mean your receiver would need two 8ohm subwoofer outputs.
Most receivers only have one output.
Most home audio receivers have powered subwoofers for this exact purpose.
The subs draw alot of power from the receiver so most companys build their power amp separate.
My advice? Either get an 8ohm sub or separately amplify the one you have.
