@@volunteeraudio Most definitely. I have a trip planned early spring next year to ride The Dragon. I’m hoping we can get together for you to do an install of an amp, front speakers, and some rear speakers on my Road Glide Special.
I've heard that most Class D power sports amplifiers cause interference with FM radio reception. And, I've also heard that the motorcycle amp from ARC Audio is one of the best amps to use in order to play FM radio stations. Is this new Hertz amp a good choice for use with FM radio reception?
All class d amps cause fm interference, it’s best to have a rear mounted mast antenna. Led lighting causes even worse interference, hidden antennas never work well in the fairing, a lot of people will claim their amp causes less interference but I have no way to accurately test this.
Any amp we have tried that had some SERIOUS POWER messed with FM reception on a Harley. The louder you turn it up, the worse it gets. ARC included. Moving power wires and amp orientation barely changed it along with antenna cable and antenna placement. iHeart radio streaming if you want FM is my recommendation. Now Kicker and Fosgate don't appear to have that problem as bad, but that's entry level stuff at best!
Did you ever do a high level input dyno run on this amp. Amazing amp , I’m just curious and would run it that way on my bike if and when I get one. Thanks , love the channel and shop.
When does this amplifier actually come out? I noticed it's a pre order right now. I plan on ordering a stage 4 kit and wanted to install before the cold weather comes around.
So your saying when set you gains lets say your using the Soundstream hdhu14+ head unit the eq is flat turn volume all the way up then set your gains on the amp just before clipping then you leave your eq flat always? So i guess my question is why have an eq in the radio if your going to leave it flat all the time.
I have 8 speakers on my 17' ultra. 6, 6.5's and a set of 6x9's in the lids. I'm also running a dsp on my bike. I'm looking for more control of all of my speakers, that's the reason for wanting to run 2 of these. What amp rack will house 2 of these on an ultra limited?? Thanks.
Hi Jay,Hoping you can give some info.SP4.900 amp if running 4 hertz 6.5 neo coaxial speakers and GTS radio with your flash.What are you setting the high pass filter frequency too?The 6.5 neo freq starts 100hz.Were about on the frequency dial are you setting them?50-5k and no markings on dial
Our plug n play amps come set by us for the speakers, we use a cc-1 crossover calibrator to dial them in perfectly. The hertz speakers play much lower than specs show
With this amp plug and play what speakers would you recommend in a 2023 Tri- Glide ultra. I’m a retired Disabled veteran and I’ve been watching your videos and I think I can install it myself but can you give me a total cost shipped
Would this amp be to much for four Infinity Kappa perfect 6.5s on an 18 ultra limited? I think I would prefer the Infinity’s since the play lower than the Hertz’s.
Hopefully you get this but on the 4.900 can you run 4ohm speakers on channel 1&2 and then run 2ohm speakers like say the cicadas 6x9 2ohm speakers on the rear channels 3&4? Just looking to get more power to lets say lid speakers. Thanks
Have you been able to fit the hertz sp 4.500 in a 2012 road glide. I am struggling to find room using the precision power amp install kit and tried a few different other amp plates with no luck. Seems like its just a tad to big to fit anywhere in there.
@@volunteeraudio do you have any pictures or videos of how yall mounted it to the amp plate. Mine is hitting my sx165 neos I installed and still rubbing outter fairing just a tad. I'm afraid it will wear a hole in the outter fairing eventually. If I slide it forward a bit it hits the headlight housing on the outter fairing. I have watched and searched through your videos but all I can find is the one where you mounted the precision power amp on a road glide similar to mine. I love all your videos and how detailed yall are explaining stuff. I recently ordered the hdhu.9813rg from yall and that thing is awesome.
@@volunteeraudio Jay, I currently have 6 speakers (fairing, tour-am and lids with the Hertz HMP4D-SS from you guys) I want to add 2 of the new hertz subwoofers in my saddlebags, but don't want to add a amp in there. What amp or amps would you recommend that could fit behind the fairing, so I don't have to add one to my bags? Thank you in advance for your feedback.
quick question, will i be able to put this on 21 Road King Special? I ask because of the bluetooth that I would need, I don't have a system yet, i'm looking for the amp and speakers 2 on the saddle bags and 2 on the lower front fairings, that is my plan. I appreciate your feedback.
Price varies because we sell just the amp or many different plug n play variations. You can see all of these options with pricing at www.volunteeraudio.com

@@volunteeraudio Man. I purchased one, but it’s going on my bike this week. If I’m not happy with it, I’ll remove it and send it to you to dyno and compare. Wish I had two of them. Even better, if Diamond was watching , they should send one to you to test.
Jay can I order one of these amps and you tune it before shipping. Going into my 13sg and using sx165 and the hertz tweets. Alpine bt headunit. The tweeters have their own crossovers.

Awesome! Thank you for watching!
Did you ever do a high level input dyno run on this amp. Amazing amp , I’m just curious and would run it that way on my bike if and when I get one. Thanks , love the channel and shop.
We did and got the same total output and every install we do is high level

It's in the Kenwood XR excelon line they are all the same anything that's DMX/DDX lines

You can but the hertz sx690neo are a much better speaker and by running 4ohm you still have availability for a second set or tour pack speakers
