Maybe this is a stupid question but here goes.... I want to build
a sub-woofer for my stereo but I need some help designing the thing..

 I can handle the low pass filters, (they are built and work well ), but 
I want to drive a single 15" speaker , not one per channel...
 
 Does anyone know of a passive summing circuit that will handle 120 watts
per channel ? I've heard that tying the two filter outputs would be bad
as one channel may try to "drive " the other and blow the amp.

A circuit would be great, even a reference would help..
thanks.....				sans
