OK ,, so if that was using a 1000hz tone, take 30.63 x .7071 = 21.66 x 21.66 = 469 divided by 4 = 117.29w RMS at an unknown THD% ,,, but probably less than 10%, which is where you will certainly notice it with your ears,,,

This means essentially every single amp (including the ones you sell) don't play at the advertised voltage...not even close.

Do a little research on the internet, on how the CEA standard was established for RMS amplifier ratings, many years ago, and then we can begin our testing again.
I can tell you that a more practical way to compare amps in the Harley environment, is to establish an identical track of music from the radio, with a good decibel meter, in a consistent spot over the seat, interchange 4-ch amps, one after another, adjusting input gains up to just the point of sounding ratty, to get the max out of each one ,,,, and record the decibel level readings ,,,, that will also open a great many eyes ,,

I think that DSPs are a great addition, but remember, here at JMCorp, we supply 100% plug-n-play ROKKER speaker/amp kits that are simple to install, and do not require ANY modifications to the radio, the motorcycle, the wiring or the electrical system.
And still provide the customer with an audio system that they can be proud to use on the highway at high speeds and show-off a little during tail-gate parties.

@Buelligan666 looking forward to seeing how it works for you and what voltage level you're able to get prior to clipping. Are you going to run a DSP? If so which one? I've used bot the Daytona Audio DSP-408 and the Mini HK. Both are good units, but the size of the Mini HK is what sold me this go around. I had the Dayton DSP in my '15 Ultra Low but was only running one amp. I'll ultimately be running 2 amps in the CVO Street Glide and needed the extra space the Mini HK provides.

I am looking at this amp as well but what gets me is all the higher end amps like SD 1200.4 or hertz or ARC audio,Focal FDP is not putting out 240X4@ 4 ohms if find it strange that an amp that cheap is putting out that kind of power compared to the bigger companies.Hard to find good user reviews not many out there.

Can't speak to the 1000, but the 1600 is red on mine when operating.
