Boon Posted June 8, 2010 Report Share Posted June 8, 2010 Grab your DMM and a tone at whatever you want the SSF to start rolling off at. Disconnect the subs. Set the DMM to VAC and connect it to the speaker outputs of one amp. Play the tone and turn the SSF until the voltage starts to change. Connect the DMM to the other amp, and do the same. Voila, matched SSF. If you have a scope, connect 1 channel to each amp, set the scope to Channel 1 minus Channel 2 then tweak it until you get a perfectly flat line. 10.x volts fo' life!
