Hi Marcus -
Thanks again for the info. I've checked the internet & ebay for US & Canadian availability (I'm Canadian) on the amps that you've recommended and I don't see their availability here.
I'm pretty much locked into the Blaupunkt HU - bought & paid for. The larger amp size possibility due to the MT is interesting, though, and may open up more possibilities for me.
You've been a wealth of help here and I really appreciate it. If you have any other insights or information just pass it along. I'm grateful.
John
