Can somebody tell me the ohm rating of oem non-hk speakers in 2004 MCS? I plan to series the front and back speakers to give more power handling after I install my Alpine KTP445U which will be set as 2 channel power pack.
1 Channel will power a custom 8" speaker box in the back cargo area.

I can't find data in my Bentley Book.

Thanks.

 

ED955S I'm no expert but I think I read somewhere that all the speakers in my R56 MCS were 4ohms and when I did the channel swap my OE/BMW A pillar tweeters confirmed this. (I tried to attach a pic.) Should Gen1s be different?

The same info seemed to infer that HK stuff was 2ohms and not interchangeable...

This probably hasn't helped much but it may 'jog' the memory of someone more knowledgeable. Hope it helps.

 

Should be 4 ohm

 

The combined impedance of the speakers and tweeters and crossovers will be 4R nominal per channel.

 

Here is the rear bottom door speaker on the base system of the R50 r52 r53. And Rear base system speaker on the R52.

Looks like 4 Ohm

Thanks.

 

Thank you ECS and to all who chimed in.

 

Welcome. Glad I could help.
