Dayton Audio SPA500DSP Class D Plate Amplifier Installation

I'm using the Dayton Audio SPA-F Subwoofer Plate Amplifier Mounting Frame to mount the SPA500DSP Class D Plate Amplifier to the OUTSIDE of my sub box, all from Parts-Express. PLUS, I'll be adding the Audio Control Phase Coupled Activator PCA to the system, in the next video.

Nice video!
Earlier this year, I sold the old Paradigm PS-1200 12" powered subwoofer that I was using in my 1986-vintage Tiffen Allegro motorhome. I miss it, and decided to replace it, and go "even bigger" (because why not?) ;-)
I have a "Used - Like New" Rockville SBG1184 18" Passive 4-Ohm Pro DJ Subwoofer on the way from Amazon.
And also a used Dayton plate amplifier of the same model you just installed, on the way from an eBay seller.
Both are rated at 500 Watts, RMS, 4 Ohms.
The plate amp cost $224.30, delivered, and the sub, $129, delivered.
JUST what every little RV needs!
The new sub is:
23” Wide
18” Deep
26” High
With the plate amp retrofitted into the sub enclosure, the combo should weigh about 60 pounds!
It's going under my new fridge...

That sounds STELLAR!

Class A/D might be the go. 😮

[@consumertechcheck]

I know some companies have built class A/B -D hybrids. Such as the class A/B section is for the main speakers, and the class D section is for the subwoofers. Which is a great idea. For anyone arguing the sonic differences between classes, most of those arguments go away, below 100hz.

Nice project very cool. I would wing it and wire it 2ohm...

[@mannyd1392]

THE RESISTANCE CAN BE MEASURED IN OHMS WITH A REGULAR DVM FOR SURE AND IS ACCURATE. THE Z OR IMPEDANCE IS MEASURED ALSO IN OHMS TAKES INTO ACCOUNT THE DIFFERENT FREQUENCIES UNDER LOAD. THESE ARE NOT THE SAME THING. GOOD LUCK AND THANKS FOR BRINGING THIS PRODUCT TO MY ATTENTION.

[@consumertechcheck]

Thanks for your feedback. I did test with my multimeter… and that confirmed everything.

[@mikeryan2802]

Turn down the microphone gain. Please. Great info.

[@consumertechcheck]

I couldn’t agree more…
I will for sure, next time.

According to Dayton techs, this amp is not 2 ohm rated, I have one, great amp. Mine is dead quiet - no hum at all with a long RCA connection. (25 feet).

[@consumertechcheck]

Thanks for the feedback… I’m glad I never tried 2ohm load on it. I too am thrilled with it. And yes… the hum is gone. It was just something with my initial setup.

I have the opportunity to get a pair of Bose 4001’s and 2001’s in mint condition for 175$. My budget is extremely tight so I feel like this is pretty solid. Thoughts? Also what’s the update with your DML walls? was it worth all the effort?

[@consumertechcheck]

That sounds like a great find for those Bose speakers! Sometimes people just want to part with things which can make for some pretty good deals. I am still extremely glad that I did the DML wall, and I remain committed to putting more exciters behind drywall everytime I have to open a wall. They sound impressive. Definitely NOT HIFI quality, but for what use them for, mainly background music while entertaining friends at the poker table, it is plenty impressive. Next time I will likely add an inwall subwoofer to compliment the lack of bass. This system however has thunderous bass due to the bass shakers under the floor. The bass in this case has never been an issue for that reason, but without them, it is rather terrible in the bass department.

Do you still have the hum sound when the input cable is disconnected?.

[@consumertechcheck]

Oddly... the hum is gone... I will mention that in a followup.
