@waytoomuchstuff ....As for the 2nd spouse 'issue'....I'm sure the 'work-around' has proved to be the least of the mystery...😏
As for multi-channel amps....I've more ways to 'skin that critter than the critter worries about' in that department of redundancy department. *s*
The sub has it's own amp, and if any item or pair needs more, it's available.
All 'clean & dark' enough for this immoral mortal.... ;)
