Is that right? Anyway around that?

I keep saying that, after 4 years in the market, average audio installers still do not know too much about the E9x 3 Series sound systems.
There's no need to "rewire" anything, I don't even know what that means in this context. You either get a 2 ohms stable amp to drive those 2 ohms speakers or you don't. And right now I would say that 100% of aftermarket amplifiers that really are worth something are 2 ohms stable.
For example, the two multichannel amps in my post above are 2 ohms stable. However, depending on which amp you choose is the wiring configuration:
PDX-5 = OEM components (2 ohms) driven by channels 1-4 directly and a pair of SWS-8 in 4 ohms wired in parallel driven by channel 5 (mono).
G6600 = OEM components (2 ohms) driven by channels 1-4 respectively and a pair of SWS-8 in 2 ohms driven by channel 5-6 respectively (stereo).
FYI: I'm in the final development and production of a custom harness to allow direct plug in interface with the main OEM amp connector in the trunk, so the OEM amp can be fully replaced while no OEM cables will have to be cut to add any aftermarket amp or processor to the OEM HiFi (non-Logic7) system. It will include a relay with fuse protection for the OEM remote turn on signal. It should be for sale in around 6 weeks for current 3- and 1-Series and the E46; this will greatly simplify the installation and thus considerably reduce the installation costs.
