hi all after some further research on audiogon forum i have come across a solution that i like, i've re-pasted it here rather than typing it outmyself.
from mkgus:
the best way I have found to do this is to grab the signal off your main speaker amplifier binding posts, after it has passed through the amplifier. Drop the voltage to line level and run that through a dedicated subwoofer preamplifier.
i would like to ask what are some recommendations for new or used subwoofer pre amps that i can use? i have two subwoofers that i need to connect. does this mean i need a pre amp with dual outputs or can i just use a y adaptor ?
and how do i get the signal of the main amplifier binding posts as it is already being used to run the main speakers with banana plugs. do i just insert bare wire from the voltage divider ?
