sub wiring difficulty

i am an idiot wrote: He has a 1 channel amplifier. Stereo is not an option.

Oppps..didn't read the model # i just saw the "per channel" description. So i just figured....Are u sure u wanna run two woofers in series?

http://mobile.jlaudio.com/support_pages.php?page_id=163 read this plz. "It is far less desirable to make subwoofer to subwoofer connections in series. Because of slight and unavoidable differences between speakers and because of the high likelihood of uneven loading between different speakers in a car, there will be slight differences in the mechanical behavior of the two speakers in series. These differences in movement result in induced voltage (called back EMF) being created by the speakers across the series connection. This effect causes a problem when two speakers which behave differently are connected in series because the speakers can modulate each other (cause each other to move), resulting in distortion. The problem becomes more serious as more speakers are connected in series."

Yeah you gotta watch out for that Back EMF.  The distortion that is caused by the series connection may be audible, but most ears will not even notice it.
