ok, so. i hooked up my new xpa-3 to my new 01txh. no issues, until i hooked up the sub. i didn't change any settings on the 01. just rca's to xpa and speaker wires. and of course the sub out. i only played it in stereo, but other setting didn't get any lfe. the manual says simply not hooking up speakers wires is all that is needed to use the preouts.
