I have the base HiFi 676A in my E90M but need to step it up. Thinking about swapping in the IA/EPS speakers as well, with the Audiotec Fischer Match UP 7BMW amp. Are all of the IA speakers (not the subs, but the components/tweeters/crossovers and coax) happy at 4 ohms?

Cheers.
I did start with the logic 7 system. The BMW IA speakers are definitely a step up from the logic 7 speakers. I'm glad I did this.

4ohm isn't a big deal as long as you have an amp that can power them. The JL Audio 600/6 v2 at 75 watts a channel at 4ohm has more than enough power.

You'll need to run some quality, jacketed speaker wire to the center and put one the end of it into the harness and put the other end on the teal two pin plug in. You'll need a special crimper & pin kit.

The pins you need to add to the OEM harness are considerably bigger than the ones I listed above. I'm not sure what size they are.
