I am working on setting up my 5.1 home theater system and have a question on powering my passive sub. I bought a new Denon (2313 CL) receiver and no longer have use for my old Yamaha (RXV2300). Instead of buying a new sub amp as well would I be able to use my old Yamaha to drive the sub? If so:
*What inputs should I hook the sub to on the Yamaha( front left,right,rear etc)?
*How should I hook the Denon up to the Yamaha?
*What settings should the Yamaha be on?
Without doing a lot of research I would guess it isn't possible. You have a receiver and you need a power amp without a preamplifier stage in front of it. You can buy a plate amp for your subwoofer for as low as $60 depending on the power you need.
I think this should work, I did something similar a long time ago.
I ran the sub out of the receiver I was using to one of the inputs on the old receiver, let's just say it was the CD input. I then hooked up one of the speaker outputs to the passive sub. Worked perfectly.
I did the same thing as raynist. You can use the main AVR to control the frequencies that you send to the secondary receiver (amp). You use one channel of the secondary receiver and connect to the high level inputs on the passive sub.
Thanks for the responses. So does it matter what channel I hook the sub two. How do I hook the avr to the Yamaha? Do I run a cable from the sub output to the "cd" input as ray it's suggests. I notice a sub input connector on the Yamaha receiver.
So i got this working based on the suggestions above. Now I have a few follow up questions:
I have a Sonance VP85W in wall subwoofer rated at 150W max. The Yamaha receiver I'm using to drive the sub is rated at 110W per channel. AmI not doing the sub justice by using this receiver? Also, would it be possible to bridge the left and right channels of the receiver to send to the sub to double the power?
