Aura Base Shakers (8) UPA-200

[magunder]

In my home Theater I am looking to change out my current (Loud) Pyle PQA5100 5000W AMP to an Emotiva AMP so it will be the same as the rest of the equipment in the cabinet. The home theater has 8 of these Aura Butt shaker Pro's... One in each seat which are rated 4 or 8 ohms. Could I use a UPA-200 with these? would it be enough power to drive all 8 shakers? I know its probably overkill for such a nice AMP to drive Butt Shakers but I want the same equipment.

Are these the 35w bass shakers? Upa-200 will work just depends whether 4 or 8 ohm as to how you wire

I have them wired per the attached, They are rated at below:
• Power handling: 50 watts RMS/100 watts max
• Impedance: 4 ohms

I also have one opening on my XPA-3 that I thought I could use for this but didn't know if that would work?

Thanks for your help,

So that wiring that you show is series wiring which will result in a load tot he amplifier of 16 Ohms. This is going to give you a pretty low output from the amplifier in regards to ratings and the bass shakers may not work well. Consider wiring a pair of the bass shakers in parallel and the wiring the 2 pairs in series. This would bring all 4 shakers on each channel to their original rating of 4 Ohms and provide you the power you are seeking. If you need help with parallel vs. series wiring or understanding what I am saying let me know and I will explain it more in depth. I am at work and cannot brew up a diagram as you have or I would. Hope this helps.

In my opinion I would not waste an Emotiva amp on bass shakers or butt kickers. The Emotiva amp is designed to have a flat response across the full bandwidth and the price (while amaizng low) reflects that. You also have no built in filters or bass boost available. Using it to power shakers is a waste.

Buy a subwoofer plate amp. Then you have a built in high-pass filter and an amp designed for bass or at least the lower frequencies. Take the $350 you would have spent on a UPA-200 and buy something like this: www.parts-express.com/pe/showdetl.cfm?partnumber=300-807 for less and get more value.

I have helped install many of these plate amps for bass shakers/butt kickers. We have mounted the amp in a wall near the equipment rack or built a small custom box to place near the seats to cut down on wires running from the rack to the seating position. Also allows easy access to tweak your settings while sitting in a chair.

+1. Works great!!

Thanks for the Info. Is attached how I should wire them? would this be in parallel? I've looked at the plate AMP option and may go that route but will try this wiring first. Another option I was thinking of disconnecting the fan out of the PQA5100 or can this config. attached be wired into my open channel on my exiting XPA-3 or will this overload the AMP?
Thanks again,

What you posted is wiring all 4 in parallel,.... not what you want! That would provide you a 1 ohm load! That would likely result in thermal shut down or overload protection of the UPA. What you want is a mix of the two. You want to break the bass shakers down in to 4 pairs rather than 2 quads. Each of the pairs would be wired as your above photo (parallel) and then you would wire two pairs together in series (first photo) for each channel of the amp giving a 4 ohm load. Sorry if this is confusing.

Ok, Sorry to be a pain on this but want to make sue its right...
I have attached what I think is Series / Parallel, Diagram isn't the greatest. If I wire it this way can I connect to my one open channel on the XPA-3 or would this be too much load for that AMP?

Thanks again for your help,

That looks right.

[reaper60]

Yes that looks correct, if you then wire them in series to combine the 2 channels to 1 you would have an 8 ohm load that you could run on the xpa's extra channel. Would be 200 watts spread over 8 bass shakers though. You could just connect 4 and have 350 eats over 4

Cool, Thanks for your help reaper. I'll report back on how they work thru the XPA. With 8 running on one channel I assume It'll get 25w per channel?

Running at full clip yes
