SounDigital and other Common Ground Tech amplifiers short the rca outputs of modern differential rca output radios. The solution has been run high level input to these amplifiers to keep from getting crazy feedback noise in these amps. The problem is that many SounDigital amps do not have high level inputs and only have rca. Soundstream has recognized this issue and redesigned their radio circuit boards to work with these amplifiers through rca without creating this noise. Over the last 2 years we have witnessed constant improvement from Soundstream in all of their Harley radio models and this commitment to continually make better radios is one of many reasons we are proud to be partners and online authorized dealers for both Soundstream and Precision Power.

So in watching this video which was very informative on the problem it didn’t say exactly how to fix it other than purchasing a new radio or finding another amplifier. I have a Sound Digital Evo 800.4 and purchased a Sound stream reserve RG9813. The 800.4 doesn’t have high input connectors just RCA inputs. But when I turn it on I have a high pitched static sound that drive me bananas. Is there a way to fix this problem without having to buy new components? Thanks
@volunteeraudio
@volunteeraudio 6 месяцев назад
So the 800.4 evox2 has high level inputs but sometime people purchase a cheaper version that was meant for the Brazilian market. You can use a set of line output converters and it will stop the shorting issue, I don’t like this solution either and even with a proper install your amp may make terrible noises just because you have the lowest quality version of their amplifier. I would highly suggest a better amplifier. I have a bike i’m working on today that has had 3 sound digital amplifiers fail and he is finally over the garbage and we are upgrading to a hertz amplifier

Hey Jay, my issue is... i have a 21rg, with the Si radio and hertz 900 amp kit. 4 speakers. Only been installed about 3 weeks ago. Ok, my sound issue is that i can hear my bike cranking sound through my speakers. Sounds pretty horrible. Any suggestions?
@volunteeraudio
@volunteeraudio 6 месяцев назад
If voltage drops below 11 volts during crank you will hear a noise as voltage climbs back up to 14 volts, your battery is weak so you hear this noise, you can turn on the amp turn on delay in the settings menu, then start the bike before the radio has sound. If you are listening to the radio and then start the bike you will hear that noise but realistically the sound is for about 1 second and not very loud

Good to see you dive a little deeper into why you don't like SounDigital amps. I was hoping to see some proof on a scope or other tester showing the distortion you are talking about with these amps. To me, they have very similar specs as other name brand amps. So where does the distortion come into play? Any chance you can do a comparo of SounDigital vs Hertz?
@volunteeraudio
@volunteeraudio 6 месяцев назад
I’m doing an install currently for a customer that is on his 3rd soundigital amp that has failed, we are upgrading him to a hertz amplifier so he can no longer worry about perpetual failures. Soundigital only warranties their amp for 1 year and hertz covers theirs for 3. There are many factors that come to play when choosing an amplifiers and we see all the problems on a regular basis with soundigital. I can’t have someone drive from California or Canada for an install and use an amp I know will likely fail within a year

@@TonyDL to get there rated power you must test one channel and you will get the rated power at about 30 percent distortion, where as the industry standard is less than 1 percent, with the tools I own I can not show distortion in this manner but I have friends in the industry that posses these tools but chose not to burn bridges as most move from company to company for work

@@volunteeraudio Thanks for your input Jay. I guess it will remain a mystery... so many advocates for SounDigital amps on Harleys out there touting their small size and good power output at a reasonable price. I would love to see someone demonstrate the distortion you refer to. I am using their 400.2 EVOX amp driving a pair of Hertz SX165 Neo's and it sounds good but not great and I have no way of knowing where the weak link might be.

First I’d like to say this was a good video on explaining the noise issue. But I would have to agree with @sherminl1284 a that you should have moved your mic to the speaker the same way you did on the first part. I see you replied that you did not feel the need to do that for the second part as you did not hear any noise. For the first part I could not hear the noise until you moved your mic to the speaker. So It would have been nice to hear what the noise sounded like with your mic placed up to the speaker in the second part as well.

The solution is high level input to your sd amp, newer si radio if your going rca or a higher quality amplifier.
