Looking For Decent Amp(s)

[Daniel Johnson]

Ok, so I'm attempting to hook up 4, 50-watt bass shakers to my office/gaming chair via a bluetooth receiver and an amplifier for feedback while gaming the way a controller for a playstation or xbox shakes, but much stronger. The only problem I'm having so far is finding a good amp for this project.

I can either use one amp capable of 200-watt rms, running 2 bass shakers on left and 2 on right, or I can use 2 amps, each of at least 100-watt rms, sending the left signal to one and the right signal to the other.

These bass shakers are 4-ohm each, so the amp needs to be capable of either 8-ohm (subs in series) or 2-ohm (subs in parallel).

And as I've stated already, this is going to be used for an office/gaming chair indoors, so I don't think car amplifiers would work, it needs to be able to plugged into a standard American power outlet.

A variable crossover/low pass/high cutoff on the amp is preferred as well, since low frequencies are best at creating vibrations.

Any help is very appreciated, thank you guys.

Would the SMSL SA-98E 2 * 160W TDA7498E stereo digital amplifier be able to handle at least 2 of the 50-watt 4-ohm bass shakers?
Or would the SMSL SA-160 160WPC Digital Amplifier do a better job of this?

And, would purchasing a larger power supply have any added benefit for either amplifier? I know it can help certain amps.

Also, would a small cheap pre-amp like the BEHRINGER XENYX 302USB have any added benefit, since I'll be filtering out all of the audio above about 200Hz anyways via a low pass filter?

Thanks guys

Well, I think I've figured it out finally after several days of searching and research.
I think my setup will be sending the audio signal from the PC's USB Bluetooth USB adapter to a Bluetooth receiver, which then sends the signal via a 3.5mm-to-RCA cable (which has a left and right obviously), but I'll use a 1-female to 2-male RCA Y-splitter connected to each, effectively giving me 4 RCA cable connections, 2 left and 2 right. Each one will be plugged into its own 100Hz RCA-style low pass filter, which in turn will be plugged into their own SMSL Q5 Amplifier, which provides a maximum of 50 watts output @ 4ohms, in the appropriate input port, giving me 2 amplifiers for left and 2 amplifiers for right. Each amplifier will power its own 50-watt 4-ohm Aurasound tactile transducer, giving 2 for left and 2 for right, via 16 gauge speaker wire. And all of this will be mounted on the bottom-side of an office chair for tactile feedback while gaming, except 2 of the tactile transducers will be mounted on the back of the chair. Also, all power connections will run to the back of the bottom of the chair to a 6-way outlet adapter, which will be powered via a single extension cord from any standard outlet.

I'm still unsure whether or not a larger power supply would provide any benefit for these particular amps, but I don't think it will be necessary. And I'm almost certain a pre-amp mixer is virtually useless for this application.
