Yes, sound quality is a whole other issue..again, not my recommended route.

The instructions you pointed me to involving placing a non-polarized 15 mF capacitor in line with the pre-amp outputs of the Blau headunit worked like a charm! No more popping noise and avoided expense and hassle of replacing Bose amp and speakers.

For others intersted, I could not locate 15 mF capacitor so I ended up using a non-polarized 10 mF and 4.7 mF capacitor, wired in parallel, on each channel.
