Okay I had an old RCA reciever kicking around and iam using it as a pre amp for my new bass shakers. My current amp is a yamaha rxv-730. Iam wondering how will I wire the two together to have the RCA power the shakers. The simpler the better.

Bass shakers? What, a subwoofer? Don't these bass things have amplifiers built into them already?

What signal-output connections does the RCA unit have on it?
What is the model of the RCA? Are there any documents or web pages explaining it? Can the Yamaha accept a preamp signal into its amplification stage?

Ok, a quick search online yielded the RCA RT2280's user manual:
http://support.tandy.com/support_audio/doc66/66651.pdf

And the user's manual for the Yamaha RX-V730 is:
http://www.yamaha.com/yec/customer/m.../RX-V730_e.pdf


Page 6 of the RCA manual shows a "Subwoofer Pre Out" which you can send to a powered subwoofer.

Page 15 of the Yamaha manual shows no the connections there, but you may be going down the wrong path here. Who makes these bass shakers, and what's the model number? Are they powered bass units or do they indeed require amplification beforehand?

They are the 25 watt auras. According to the manual they need a seperate power source

Ahh, I see. These are actual seat-shaking devices that are powered like regular speakers, but only work to about 70Hz.

Ok, take the subwoofer output signal (not from the speaker connector, but from the round connector for the signals) from your Yamaha receiver and connect it to your RCA receiver through its subwoofer connection (in the 6CH. DIRECT INPUT group of connectors). Connect one bass shaker to the spring-clip terminals labelled "SUBWOOFER".

Run the RCA receiver in 6-channel/direct mode and adjust the RCA volume and the Yamaha volume while some song is playing in order to get the shaker working.

If you need to hook up another shaker, let me know.

You have a sub as well as shakers? How are you connecting all this up? The more descriptive you can be about what you are trying, the easier it is to solve the problems.
