Hi guys! I hope that someone here can help me connect my passive subwoofer to my stereo receiver. To explain my predicament, I recently purchased a cheap "home theater in a box" (Insignia IS-HTIB102) setup for the bedroom, replacing a defective unit. The speakers for this set are absolutely HORRID, but the receiver/5 disc CD changer, and the included subwoofer work well. The pre-existing speakers are sufficient for my bedroom setup, (Sony SS-MF315 tower speakers and JBL surround speakers) so the speakers that came in this setup are destined for the garage. In my home office I have a couple of Sony SS-MB350H bookshelf speakers running off of an old Technics SA-GX290 receiver. What I'd like to do is connect the passive subwoofer (190Watts) to my home office receiver to give me more music bass. There is no TV connected to the setup, and it's NOT going to be used as a home theater setup. FM stereo and CD player only. My problem(s) : 1. The subwoofer only has two speakerwire connectors on the back, just like a regular speaker. One red, one black. No other connectors, controls, etc. 2. My receiver has red/black speakerwire connectors for Front left, front right, surround left, surround right and center, but NO subwoofer connectors. I sooooo can't afford to screw something up/burn anything up, and am afraid to experiment unless I know that the connection is safe. Questions: Is it possible to hook this up, or am I dreaming? Can my left or right main speakers share the receiver red/black speaker wire connectors with the subwoofer, or would that cause my system to screw up? If it is OK, what would be the most appropriate (non technical) way to connect these? Honestly, besides connecting red speakerwire --> red connector, I KNOW NOTHING about home audio. THANK YOU IN ADVANCE FOR YOUR ASSISTANCE!
