Uh oh, I think I walk the wrong path then. Ken, is there anyway to salvage the use of the 340 system. I think the tweeter drivers for System 240 and 340 are the same. Do you think it will work if I used your custom made cross over that can play down to 2500Hz (like you did for the other X5) so I can mount the tweeter in the dash and save my mid-range for some other applications?

I think I am going to ditch the LC8 Audio Control Idea too and go your way with the Jensen Isomax. One more thing, Ken, the pre-out wires from the DSP amp that you mention, are they the one from the module right behind the battery like Aus showing here http://forums.bimmerforums.com/forum...9&d=1089180285 and here (close up picture) http://forums.bimmerforums.com/forum...0&d=1089180355 or at the amp? Thank you so much for your help, Ken.

Justin.
