The biggest problem with stereo bass is that there sometimes is,
indeed, a difference between the 2 channels. A pipe organ, for
example, recorded with a pair of spaced omni microphones, can show
differences of 3db between the right and left channels due to the
side to side alternation of the lowest pitched pipes. Although you
can't tell which side the sound is coming from when you listen, your
system will have to supply more power on one side than the other. You
have to buy 2 equally powered subwoofers, since you don't know which
side is going to be called upon to supply the majority of the output.

1. who says you can't tell?

2. you need the power that you need. if you run out of power, upgrade
both amps. or one stereo amp. i'm one of these guys that thinks one
should never run out of power. to become preoccupied over the loss of, at
worst 3 dB is crazy.
