Hello,
If you are talking hooking them up in a speaker project like lets say 2-8" woofers. If they are both 8-ohm drivers and you hook them up in parallel you would have 4-ohms and would add about 3db but needs more current/power to drive them. If you hook them up in series you would have 16-ohm load and would loose 3-db.
If you are hooking up two sets of speakers this can be done only if they are an 8-ohm load and only if you amp is 4-ohm stable.
Like Ehart said you can use a impedance matching speaker switch box. I use a receiver for my home theater setup that runs my kitchen,deck and bass shakers thur a switch box and run a 5-channel amp for the main speakers.
Cheers
Bob
