What, exactly, do those words mean? Think carefully. It's not what you think.

Go to this link and download the manual for this unit. Read carefully the specs page. Along with the power ratings, something else doesn't jive between what the advertisment vaguely implies and what the specs clearly state on page 6 under speaker impedance.

Are the 901's 8 ohms or 4 ohms? If 4 ohms then I wouldn't trust this Pyle model to do the job. Read the specs above: you will note the "bridged" specifications are for 8 ohms only.

As I implied before, if an amplifier will do bridged into a 4 ohm speaker, it will says so explicitly; also it will provide a 2 ohm stereo specifications. This is because, as markw said, the bridged amp "sees" half the speaker's impedance, hence a 4 ohm speaker = 2 ohms to a bridged amp.
