I have the 10 speaker sound system in my '88 560sel. Are the speakers 4 ohm or 2 ohm? I got a Nak CD45Z for Xmas. Any suggestions about how to set it up?

I have pretty much confirmed the stock system uses 2ohm speakers and the series wiring method wont work unless you add 2 more speakers and sperate into 2 speakers for front group and 2 speakers for rear group. Also the 10 speaker designation is a little missleading they are calling each or the rear deck speakers as seperates 3 each side giving 6 rear 2 door 2 dash. But rears have one signal suppy and uses resitors or crossovers to sepearte signal to the 3. So you can cosider it more accuratly a 3 way speaker.
PS I am still trying to find out if there is a sipmple cheap way to increase resistance.

Well I always thought if you used speakers with to low resitance it put to much heat into the amp.
As far as adding speakers I figure in that case might just as well replace the stock speakers with after market 4 ohm.
I thought what you said about about the restance would be the case, I have used resistors before to filter frequency like a high pass low pass of an amp.
