| Message: | | I have read through the archives and I've seen lots of discussion on this topic, but I still have a couple questions. I'm trying to keep this as "plug n play" as possible.
1997 540i w/ DSP
I want to upgrade the front 5.25" door speakers with JL, BA, or JBL woofer/mid-range or 2-ways and the matching tweeters. In order for the replacement speakers to work properly with the existing DSP amp/system, what impedance do I need to select: 4 ohm? 2 ohm? 8 ohm? Or can they be mixed and what are the consequences?
What is the maximum depth I can fit into the door; it seems like around 2 1/4" from what I can tell reading other posts. Is that correct or is it larger?
Thanks much for your assistance.
Nick
