Troubleshooting a Subwoofer / Preamp issue...

Yes I've flicked the Phase switch back and forth on the Sub, if that's what you're referring to.... it doesn't have an effect on the turntable input.. -

UPDATE: I just connected with that method. Same as before. iPod sounds great, with sub getting proper bass. Turntable gets nothing but a faint low rumble (which becomes loud rumble when I boost the receiver volume). Bass only reaches sub when I fade the balance to LEFT or RIGHT. -

So wire direct from receiver to speakers, and one of these from PRE OUT to my sub's LINE IN? And you suspect that might help? Like I said, the sub only has problems with my turntable/preamp input.. -

But the other inputs, such as line-in playing iPod, sound great and the speakers and subwoofer are powered easily/correctly - just not the turntable input. Here are the models: RECEIVER = NAD 325BEE SUB = Polk PSW10 SPEAKERS = Paradigm Bookshelf Speakers (model unknown, maybe SE1) TURNTABLE = Harman Kardon T60 PREAMP = ART USB Phono Plus -
Was hoping you audio experts can help me understand why my setup is not functioning correctly with my subwoofer. I'll try to describe everything as simply but detailed as possible. -Turntable hooked up to stereo receiver. Turntable & receiver have no preamps built in, so turntable is routed through an external preamp (ART USB Phono Plus) -Speaker wires run OUT from the stereo into the SUBWOOFER, OUT from sub into Left/Right speakers (there is no direct SUB OUT line on receiver). -When playing records, subwoofer gets NO bass (or ALMOST no bass). If I turn receiver volume up louder, sub just gets awful LOW RUMBLE throughout song. Even with the "LOW CUT" filter enabled on preamp, it has no effect on this rumble. -Strangely, when I adjust the Balance from Center to full LEFT or RIGHT, the sub kicks in and sounds normal. But nothing at Center. -Subwoofer sounds normal/great on OTHER receiver inputs (like playing from iPod) so it seems like a turntable/preamp issue. Any ideas what I'm doing wrong?? Thank you for your help!
