SOURCE: Realistic MPA-35 amp by Radio Shack
It's not that this amp isn't like "newer amps" with + and - terminals, it's that this amp is made for public-address system use. This kind of amp is used in a store, for instance, to pump background music through speakers all over the place. The terminals you connect to are determined by total impedance of the speaker configuration used.
Most single speakers, or the two- or three-way cabinets for home stereo systems, are 8 ohms. If you're connecting a single speaker you use the "common" and "8 ohm" terminals on the rear panel. With multiple speakers, you need to figure out the total impedance and use the appropriate terminal. In series, impedances add. Two 8 ohm speakers in series would total 16 ohms, so you use the common and 16 ohm terminals. In parallel, the total impedance drops. Two 8 ohm speakers in parallel total only 4 ohms. You need to figure the total impedance of the speaker configuration and connect accordingly. Too great of a mismatch will damage the amp or speakers or both.
You might be able to find the manual for this amp on Radio Shack's website. Here's a link to the manual for the model MPA-40 which should have similar output terminals. The basic information about figuring out total impedance and general use of PA amps applies to your amp as well.
