YES, THERE IS A PROBLEM! DON'T CONNECT AMPLIFIERS IN PARALLEL!!

This is personal choice based on your own opinion of how good they
sound and look.

Yes, there are "wireless" speakers, but they will require power wiring
or TONS of batteries, and the transmission range is often very limited.
For a similar sound quality, wireless speakers should cost more than
wired speakers.

well, duh! They should always be run in series! Connect the speaker outputs
of the first amp to the line input of the second amp.

The advantage of series over parallel is that you'll only blow one amp.

Only up to a very low point. There are no high quality wireless
speakers on the market, yet.

I guess the term phasing properly might apply. Some PA amps
put two amps in parallel and it can work IF done right, but
DON'T do it normally.
