Question about Alpine CDE-9852 CD Player
Hi i have brought the Soundstream sst6.6 tarantula 2 way speakers and they are 3 ohm. On my pioneer head unit it says nothing under 4 ohms can be run off deck, but i have a Alpine cde 9852 but i have lost the owners manual and dont know if i can run the speakers off it. I do have an amp coming to run them but it will be a while before i get it.
Bozo21- Yes in fact you can run the speakers,most speakers dont run the actual load rated. An 8ohm speaker for example may check at 6 or 10 ohm.Also the speaker wire you are using will add to the ohms. cooltekMar,4/08

In actuality the resistance of the speaker depends on the frequency the speaker is playing. For example, a speaker may have a 3 ohm resistance at 80 Hz and a 9 ohm resistance at 300 Hz. If you were to make a plot of resistance versus frequency you would get what is called the impedance curve of the speaker. Also, speakers act in some ways as inductors and capacitors so a true model of a speaker must include those components as well. How does this affect the sound you ask? Well if you have an amp that has very weak current capability it may work fine into perfect 4 ohm loads but when you connect our real speaker which has an impedance dip at 80 Hz the amp may have difficulty and smear sounds that have 80 Hz components. These are minor but audible effects. This is why it is good to get a 2 ohm stable amp even if you never plan on running 2 ohm loads.
