Very poor audio reproduction on the highway over 90km/h (55m/h) I waited for the Volunteer Audio A2B unit (that necessitates complete removal of the Rockford Fosgate amp either 200watt or 500watt) and Hertz amp and speakers to come to market however for just the base package at $2,146.96 USD after postage and conversion to AUD (I live in Australia) it was prohibitive. NVS offer a DSP and power amp were the Rockford Fosgate power amp is retained and the DSP tides up the signal and steps it down prior to going into the second power amp. The cost for this package is $1,799.99 USD, once again cost prohibitive once it landed in Australia.

I tried coming out of the Rockford Fosgate 500watt power amplifier into a Diamond Audio MSDSP88 (that was claimed was claimed to handle 24volts loudspeaker line level input) running into a Soundstream ST4.1200D power amplifier, however, it was either overheating or some other error was occurring somewhere in the system so I removed this set-up. I went back to the Rockford Fosgate 500watt power amplifier and installed DD Audio VO-XN6.5-S2 (2Ohm) loudspeakers in the fairing and DD Audio VO-XN6x9-S2 (2Ohm) loudspeakers in the saddlebags. As a note I had previously tried the Hertz Neo 6.5's in the fairing and then Polk MM652 6.5" in the fairing and Polk MM692's in the saddlebags with and without the Diamond Audio DSP and Soundstream power amp. The results were not that encouraging.

I had seen at one stage Garage Bagger Stereo did a package of what appeared to be a LOC, power amp, loudspeakers and a cable kit. Their entry level was $1,260.00 USD. The LOC took me back to the first days of the Rushmore bikes and the issues we had taming the rubbish output from that unit. Anyway this got me thinking I wonder if I could use a LOC on the Skyline OS (customers of GBS seemed to not have savage complaints.) Anyway I obtained a LOC that was rated to 80watts per channel and it didn't handle the output very well at all. I later measured output to the rear channels from the Rockford Fosgate 500watt power amp at 100% running a song and the highest momentary reading I obtained was 13.98 volts so at 2ohms this equates to 97.7202 watts. The bike wasn't running and it was in accessory mode so with the bike running this would probably be higher. So I needed a LOC that could handle a higher wattage so I purchased a Axxess LOC with a stated 150watt per channel input, the unit has four channels.

I installed the new LOC with a Soundstream SM1.1000D power amp a slightly smaller amp than the ST1.200D, however, it is claimed to deliver 125watts per channel at 2Ohms. it is a marine amp too, just the circuit board not the connectors. I retained the DD Audio loudspeakers and I had been using a Maedhawk Bluetooth adaptor so I swapped this for a Tims Stereo Bluetooth adaptor which appears to be more solid than the Maedhawk. I don't tend to use a Bluetooth headset in my helmet.

I have been speaking with one of the first companies to import and install the Volunteer Audio A2B, the Hertz amp and the two Hertz Neo 6.5's in the fairing of their 2024 CVO ST they state are outputting 100db running white noise and 50% volume. With my setup just running the two fairing loudspeakers (as a comparison), at 50% volume playing white noise I register 87.7db. In windy conditions travelling at 110km/h (68.75m/h) our maximum speed limit on a highway I can hear music no issue in a full face helmet with a lower than stock windshield (I forgot to put on my 10" shield). Keep in mind I have four loudspeakers all running 2Ohms. They are component with the tweeter mounted on a centre stork with external crossovers. As always forever looking for the Unicorn of audio excellence on these bikes.

I've seen Volunteers A/b interface. I HATE that you have to buy his setup if you want the A/B interface. And he only sells ONE setup. One hit wonder.

With the NVS kit, you can adjust the input EQ on the DSP to flatten the ugly Harley curve. So basically the same thing as the A/B with DSP and its much cheaper and you can choose what equipment you want to run.

You can PM if you want.

I just need something loud enough to hear from 55 mph to 85. The stock setup is too quiet.

However I figured the 200 saved plus them trying to sucker you into a 400$ install at the dealership seemed worth it to me so far. I worry about the quality of the amp I ordered. But they are backing it with "lifetime" tech support.
