[Shotimes] Another blasted stereo question

[Carl Prochilo]

I was just looking at Rockford Fosgate's web site to learn a little more
about this.  From what I see, their "standard" amps have a window of
operation between 2 and 4 ohms impedence.  Their high-end amps can go as low
as 1 ohm.  Man, those sucker probably do a number on the power system
drawing that much current.
