Most mono amps now a days give you multiple terminals. The older amps were a pain trying to stuff all the wires in one set of terminals. If the amp is rated at 2 ohms mono then make sure what ever configuration of speakers your running does not go below 2 ohms using both terminals. For example do not hook a 2 ohm load to each terminal. 2 ohms period between the 2 sets of terminals.

bypass amp and run new wires to all speakers ,,,, will sound better .
SOURCE: 2 4ohm dvc subs to a bxi 608 ( 600watt mono)
take the positive on the sub and run a wire to the other positive the run a negative to the other negative then to your pos and neg on the box do the same on the other side then tie your two positives and two neg together and you got 1ohm and that amp willl handle it all day

ok, connect the amp positive to the positive end of one sub coil, take the negative of that coil, and run it to the positive of the second sub coil, then run the negative out of the second sub coil to the negative of the amp.
SOURCE: only one sub works
i have 2 subs and 2 amps both wired properly but one bose not seem to run how can i fix the problem please really stuck?
SOURCE: Hello, I have inherited a McIntosh MC-7270 amp,
Well what you are dealing with is a HI-FI tube amplifier. The reason it has COM, 1, 2, 4 and 8 are because it does not have a transistor driven output. It has a transformer coupled output. The 1,2,4,and 8 are the different taps of the transformer in order to impedance match your load (speaker) with the tube power section. This amp is 270 per channel and your speakers are only suggested to 120Watts. You would use the Negative to the common terminal and the plus to your 8 ohm terminal on the Amp. This is a great amp, you should keep this and not sell it.
