Bimmertech Alpha One Upgrade - anyone tried it?
I'm considering the Alpha One sub upgrade from Bimmertech and wondered if anyone else had paired the upgrade with the standard HK system in the M3 and what the results were like? It's a bit of a toss up between this and trying to source a Bavsound Stage 1 speaker upgrade in Australia (not that easy!). If the extra bass and mid coming from a sub upgrade makes a difference I could retain the stock speakers and tweeters.
