Dayton Audio SPA500 500W Subwoofer Plate Amplifier
I made 2 of the DIY 3.0 cubic foot boxes each with the Dayton 15" HF 4ohm and each with this plate amp mounted. With the gain set at 1/4 of the way the house feels like it is going to explode. Too much amp? It also goes to red quickly on serious bass.
The level will really depend on the amount of signal coming in. It sounds like you have a very strong LFE signal. It may help to lower the subwoofer level coming from the processor in this case.

can the spa500 run 2 eminence lab 12'' pro subwoofer or is the yung sd500-6 better or do i need more power?
More power is generally going to be better when driving subs. THe main thing you would want to consider when driving two is the impedance load, If you are using the 6 ohm version of the LAB sub then you can only get a 12 ohm or 3 ohm load. 3 ohms would be too low for this amp to drive safely.

Is there a way to bypass the auto on so that the amp is always on? If I'm listening at low to normal levels the sub will go into standby and then have a loud thump when it turns on due to a strong enough sub singal. It's very annoying!
I am sorry, we do not have a way to bypass the auto on function.

I have 9 Aura bass shakers mounted to my chairs and use the SPA500 to power them. What would be the best settings for the EQ to be set if I have my Yamaha receiver controlling the rest of the sound?
I would recommend not using the EQ at all for bass shakers. They do not need it like a subwoofer would since they are not effected by room nodes like a subwoofer would be. EQ could also cause damage if too much boost or gain is applied.

Hello, I've asked this question for a different amp but I figured I'd ask for this one also. Will this amp handle a 3ohm load? Thanks again
No, none of our plate amplifiers will handle anything lower than a 4 ohm load.

The back of the amp has a plastic cover that seems like it would resonate quite a lot. Can I install the amp without its plastic cover?
We do not recommend removing the cover from the amplifier. The cover does not have a problem with resonating, but if you are concerned about it you can build the amp into it's own sealed chamber which you would have to do if the cover was removed anyway.
