I know it is a silly question, but are you SURE that the hiss isn't
coming out of your amplifier?
(have you put a scope on the speaker lines or substituted either speak=

or amp?)

Yeah, switching one speaker pretty much solved that one.


What, solved it as in proved that the amplifier *was* the cause, or solve=

When I took out the speaker and put in another one, the hissing sound
stopped? When I put the speaker in again, the hissing sound started
again


I don't know if my question was ever answered. Where is the hissing
comming from ? Behind speakers means behind the box.

If you can't tell from listening, use a piece of tubing to get location.
You can get it down to less than an inch.
