It would work with 8 ohm speakers as well, but you will have less power available. Going higher in impedance for a speaker normally doesn't pose a problem, although you are getting less power. (Ohms law)
If on the other hand, you go down in impendance, you might fry your amplifier.... :eek:

Just dont hook it up to those 1ohm bose speakers and you'll be OK. :eek:
There's very few full range speaker sets that run in 2ohm... The ID Chameleon is the only one I can think of off the top of my head.

Re: 4 or 8 ohm? (Nevermind)
Home is 8 ohm, car 4 ohm. Many amps home and car can go down to 1 ohm and even lower. For your deck, stick with 4 ohm and use very efficient speakers like coax. Look for speakers with a minimum power rating around 10w or so. ex. Boston Acoustics RX series http://www.bostonacoustics.com and http://www.tms-electronics.com
