I was recently told by a local mobile sound vendor that to upgrade the amp on my '07 E70 (w/Standard Hi-Fi..no EQ) that I'd have to re-do the whole setup due to the wacky impedence on the various drivers. Like on a Bose system.
The BavSound amp is a plug and play replacement for the stock unit. Is that amp unique in it's ability to handle the odd ohms?
Dealer full of sh!t?
