Hello,

I am new to this forum so please bear with me.I am in the process of buying a new 5.1 channel receiver and have a few(a lot) ? about the sub woofer.I have a Dayton SA240-B 240w with boost amp plate powering a 10" Mordaunt Short sub woofer and a Aura Pro Bass Shaker.I know or I think I know that the low level sub woofer RCA out put jack from the receiver should plug into the low level input RCA jack from the amp plate.The amp instructions say that the inputs are internally summed to mono.I presume that means R & L inputs are tied together so that when you plug the phono jack to the Right input it also then is wired to the Left input to create mono for the woofer ? Next is the Shaker.Can it be wired to the Dayton amp plate and on what output if possible ? Any info.will be sincerely appreciated but please do not get to technical ! Any plumbing problems ?

You are correct about the RCA hookup.


However, I don't think you would want to hook your shaker up to the same plate amp. While it could be done, you would have no way of effectively controlling the intensity of the shaker or the crossover point.


I would pick up another plate amp or some other amp to power them separately.

No problem, I will do my best to answer them if I am around.


The only other potential thing I could think of is the use of inline potentiometer/rheostat like this .

They are probably still available at Radio Shack in some form and may let you dial things in to the desired level.

It would probably allow you to control the volume if it would provide enough resistance. However, it still wouldn't solve the crossover problem.


AND add it to the same amp is either going to result in a greater load or higher current. Depending on the impedance of your existing sub that could either be too much current for the amp or too little power for the sub.
