A question to those owners of the 2023.5 and 2024 CVO's (Street & Road Glides) with the new Rockford Fosgate '500w' amplifiers, have any of you measured the output voltage on a channel? I own a Dayton DSP 408 that I had in my 2022 Road Glide Special taking it out when I recently sold the bike with the intension of installing it in my new 2024 CVO Road Glide when it eventually arrives (things are different supply wise down here in Australia). The Dayton has a maximum input voltage of 8volts which was fine on the RG Special with the GTS headend using its speaker outputs never an issue. I'm unsure if the new RF amps are outputting a bit more in the way of voltage as I don't want to cook the Dayton. Any info would be gratefully received.
Unfortunately the new Harley-Davidson Skyline OS systems runs a A2B digital system that is yet to be deciphered by the aftermarket manufacturers hence for the time being we are in a situation that necessitates taking the speaker level signal from the either the '500watt' Rockford Fosgate amplifiers in the 2023.5 or 2024 CVO's or the '200watt' found in the new 2024 standard touring bikes, running this speaker level into a DSP and smoothing out the massive low end frequency rise that H-D still tunes into its headends then output this into an aftermarket amp and onto upgraded speakers in the fairing and or saddlebags. NVS in New Jersey is using a ARC Audio DSP to approach this issue, Volunteer Audio is working on a A2B decoder to remove the RF amp but this is still in the pipeline they sell a slightly modified Kenwood system that was designed for the pre-2024 two speaker in the fairing touring bikes as a stop gap also for those people who will not want to fork out for the new Hertz system when it comes to market. JMCorp sell a system that appears to be similar to the Kenwood system with that capacity to smooth this bass boost in the amp. JM still keep the Rockford Fosgate amp as do all of the integrators currently as the system will not output if removed, hence we return to my original question does anybody know the voltage output on the new '500watt' Rockford Fosgate power amplifier found in the 2023.5 and 2024 CVO's?
You will fry that DSP putting it after the amp. The voltage is going to vary based on the volume setting. A 500w amp, 125 per channel, if factory still uses 2ohm speakers at 75% volume is going to be 15.8v. If now using 4ohm speakers you're around 22.4v.
Agreed if this Rockford Fosgate '500watt' power amplifier was outputting a true 125watts a channel, however, it appears that on an independent test it outputs 80watts at 2Ohms and 38watts at 4ohms. As mentioned NVS are using a ARC Audio PSM Pro that has a maximum 16volts RMS input with success over about the last 9-10 months. I guess I'll need to look to either this or the Diamond Audio MSDSP66 apparently it can accept up to 24volts RMS. I was hopping to be able to recycle the Dayton for this project.

I have a kit from NVS that I was trying to install on a 2023.5 CVO. I did not measure the output, but Carlos did say it was about 22V. I know someone who used a Dayton, but it was on a non CVO.
I had a bunch of issues with the CVO I was working on that no one (Carlos, ARC tech support, etc) can figure out yet. I've talked to a few guys, with a total of over 15 new bikes and no one has had a turn on pop like this one. This bike has a nasty turn on pop (about 45 seconds after powering bike on, when the radio finally turns on) and it fried the "remote turn on delay" on 3 brand new PMS PRO's. I benched tested them, worked fine, but in bike and then delay would not work. This bike must be spiking something when the radio turns on. I ended up removing everything and keeping aftermarket 2ohm speakers in. It's louder, but owner still wants more. I just can't believe how bad that "500w" Rockford upgraded system is.
Here is the ridiculous Harley EQ curve on the new HU's

Thank you cshocker for the information in particular the RTA. The comment from Carlos over at NVS is useful to know too. The system designers at H-D really should take a good hard look at themselves. Should someone at the company I work for tuned a PA system like this the installation technician would get a bit of a talking too. Line array systems sound very average with this tune in their DSP.
I saw elsewhere in the forum you mention this issue on have with the turn on spike that has concerned me somewhat too. I hope that you are able to resolve the problem.
Apparently the non-CVO '200watt' systems seem to be outputting shockingly low figures so I think the Dayton would handle these okay. I just think that the '500watt' units are going to provide just a little too high a voltage for it to work with comfortably.
Once again thank you for the information, every bit helps. Once my bike finally arrives I'll start work on it and do a bit of a report on what I find.

No problem! I did hear that the "200w" RF amps are the same power that the GTS HU's were putting out. So would make sense for use with Dayton.
I am waiting to hear back from ARC Audio tech support on what they find wrong with the DSP's and see what they think.
I'm not 100% certain that an interface will solve the problem with this particular bike. I'm 50/50 on it. I mean, there's only 2 sources the music is coming from : HU and amp. Hopefully if I can eliminate the amp, it'll solve the problem.
