Hi, I have a Yamaha RX-V661 A/V reciever, as well as a rw-10d subwoofer. I see that the subwoofer does not have a lfe-input, which only requires one cord like my previous SUB-10. My receiver only has one subwoofer pre-out output. I currently have a y-adapter connected to the receiver. This allows me to hook up the receiver single output to both inputs of the sub. Is this reccomended? Will this in any way cause damage to the sub? Are there any better suggestions from anyone? I am only 18, and am still pretty new to home audio, but I am addicted to it. I also had one more question. If my sub is put on +1 Gain on the sub amp, +0 on the receiver, and set to the punch EQ setting, how much of the subwoofers amplifier is being used? Someone told me that is using 85% of the subwoofers amp. I do not want a blown amp, so am I safe with these settings, or should I turn the sub down the sub amp? Or the receiver?
Any help is appreciated.
