Going to be less vague now; I have two Kenwood JL-750W speakers which I'm planning on using with a Sansui QRX-9001 receiver (which I don't have yet).
So would this receiver be able to drive 4 of these speakers? What about 2? If not, I'll need different speakers; what specs should I look for?
Even the most underpowered receiver will drive most speakers fine in a house venue. Wattage is really only important if U are trying to fill a gym or concert venue. About the only exception to that is a subwoofer needs a lot of power to it, and if U have a unpowered subwoofer that is separate from your main speakers, then U might need some serious wattage.
U do have to be careful to not connect to many speakers to a receiver to avoid their total resistance to be too low and overheat the receiver.
I couldn't find specs on the Sansui QRX-9001, but in most cases, the old quad receivers had four amplifiers, so if U were connecting speakers to each amp, then U don't have to worry about the impedance(ohms) being too little. Some USA speakers have a impedance of 4 or 6 ohms, and some receivers don't ever want to see any less than 8 ohms.
