Need a little help, I have been reading the forum for a couple of weeks and think I have read all the posts relating to adding the speakers to the lower fairings but have not seen describe a CVO Road GLide configuration. I currently have the boom audio speakers front and rear and amp (stock). I have ordered the lower speaker housings and speakers from the 2011 CVO Street Glide. I have seen many conversations discussing adding an amp to accommodate bikes that don't have the rear speakers and amp but none on how to wire the lower fairing speakers if you already have the amp. I am not against the idea of getting a second amp for just those speakers but really am not sure how I would wire. Any thoughts would be appreciated, diagrams are even better....


Thanks

What bike do you have?  I ask because there are wiring differences among the different models.

Carl I have a 2011 CVO roadglide...

Mark,

I'm not a tech or audio guy, but I've spent some time reviewing wiring diagrams primarily in considering adaptaing some of the newer audio upgrades to my bike, and '04 EG which have included adding the Harman Kardon radio, CB/Intercom, fairing lower speakers, amp, etc.  You should confirm what I write below with Iron Cross Audio and/or hd-dude (Jim) here who are the experts on the HK radio, especially its circuits, and any wiring mods to your existing wiring.

If you go to the first two posts in the thread below, it will show you the current wiring of the audio on your '11 CVO RG:

http://www.cvoharley.com/smf/index.php?topic=53364.0

If you scroll down to reply #5 in the thread, you'll see the pinouts from the radio.  Connector 28A in that reply shows the functions of the pinouts.  Pinouts 1, 2, 24, and 25 are the pinouts for the rear speakers--2 channels and + and - wires for each.

If you compare the wiring diagrams for your bike with the non-Ultra version, you'll notice that the rear speaker pinouts of the HK radio are unused.  On your bike, the front signal pinouts are NOT used.  This suggests that you can use these rear speaker pinouts for your fairing lower speakers directly, or for the inputs to a two-channel amp should you decide to add one.  But I'd check with Iron Cross Audio before doing anything.  Also, check with IMAbadman who is undertaking a similar project on his '08 CVO Ultra.

Just got through adding Hogtunes lower speakers & amp to my 2010 SE Ultra. Their web site shows how to add the amp on CVO bikes. It is to my understanding that you have to have a amp to drive the lower speakers. I'm very pleased with the Hogtunes set up and it was simple to install. Don't see why you couldn't order the amp and wire it to any speakers.

Thanks Carl! I will give Iron Cross a call to confirm, is there any chance of getting a PDF copy of those drawings from you, the ones posted do not print well and when I blow them up to be able to read things turn blurry..thanks again for your help,


Mark

I'll check to see if I have them as a pdf.

As the previous poster mentioned, another way to do what you want is to take the front speaker signal, before it reaches the amplifier, and split it: one circuit going to the amp on your bike as it is currently configured, and the other going directly to the fairing lower speakers or, as the Hogtunes system works, directly to a second amp, and then to the fairing lower speakers with the amplified speaker.

The reason this approach works is that the HK head unit doesn't see any load (impedance) for a signal sent to an amp.  I ran out of room in my original lengthy reply to reference the Hogtunes' website and its explanation of the "no load" aspect of splitting the HK signal.  In HT's application, the bike's speaker wiring is split inside the amp; i.e., front speaker wires go to the amp, and front and rear signals come out.  In the case of the HT fairing lower speaker kit, the front signal goes to the amp, and signals for front and fairing lower speakers come out of the amp with the lower speakers receiving the amplified signal.

I'll get back to you on the pdf versions later today, if possible.

Carl, just re-read your post and I think your idea will work, I have an 06 shop manual and I was able to see the pin outs of the radio clearly, it looks like 1, 2, 24, and 25 are the rear outputs that are not list on the CVO RG, assuming that they are actually empty I should be able to use them to drive the amp for the lower speakers. I am going to guess that since my radio doesn't have fade (front to back) those pins (1,2,24,25) may not work until I have the radio flashed. I just picked up all the parts from the dealership so I will try to play with it this weekend....


Thanks,

Mark

Mark,

The rear speaker outputs are "live" and don't require a flash; the flash is to turn "on" the fader control. 

Give Iron Cross Audio a call to confirm what you are going to do.  When I was considering a project (adapting the Boom Audio and Intercom kit that HD said was for '07 and newer bikes to my '04) I called ICA and spoke to Tony and reviewed my plan and confirmed that he thought it would work; more particularly, he had no reason to think it would not work.

Good luck with your project.

Mark,

Are you sure your FLTRUSE doesn't have fader control already?  I ask because I checked one at my local dealer a couple of weeks ago and it did have fader control between the front and rear speakers.

I was curious about the fader on the FLTRUSE because the sound system doesn't use the rear speaker pinouts and, instead, sends the front speaker signal to the amp under the tour pak where the signal is amplified and split front and rear with a working fader.  I was curious to see if the fader was present and would it work since the head unit's rear signal isn't used.  I was surprised that the fader control does work, and confused (I'm not a tech or audio expert) to hear the fader work through the amp.

The use of the amp to have fader control of the audio on the FLTRUSE is one of the curiousities/concerns about accessing the rear speaker pinouts of the HK radio and "normal" fader control at the head unit.

Carl, once again you are spot on, I started thinking about my statement and was second guessing my self so I went out to the garage last night, uncovered the bike and tested the fade control and sure enough it works perfect.  I too am curious as to how they make it work since the amp does not appear to use the radios rear channel inputs, I may get brave and pull the fairing off this weekend to do some exploring, If I do I will let you know the outcome, also going to swing by a local audio store that has done some work on new CVO's for the dealership  and see what they might be able to offer in the way of an explanation.

I spoke with Tony at Iron Cross yesterday and he discussed multiple ways to hook up the amp, of course your comments had not sunk into my head yet so I was unable to discuss the rear speaker output option, he did provide one solution which is to add a set of preout jacks to my OEM head unit and then run the amp for the lower speakers from those jacks.  I think he said about 85 bucks, if the rear speaker idea does not pan out I think this is the way I am going to go.

[Harleypingman]

Mark, glad to hear you are talking to Tony about your project because he knows his way around the HK head unit better than anyone I've heard of and should be a real asset to your project.

While it would be nice to have a fader control to esily adjust the relative volume of the speakers in the fairing lowers, the SESG2's aren't wired that way.  They get the signals for the front speakers and fairing lower speakers from the in-fairing amp from the same l/r channel and there is no fader control on the head unit.

hd-dude (Jim) installed the SESG2 speaker boxes/speakers on his bike and used the gain controls on the Hawg-Wired 4-channel amp to adjust the volume level of the fairing lower speakers which seems to work well for him.

Good luck with your project.

Carl
