It's not so much a no-no for HD since the amp is downstream of the head-unit, but it limits you too much in the variety of speakers you have to choose from and how they would be connected. For example, I wanted to reuse my Hogtunes Hog Pods (6Ω) and to achieve a 4Ω final output I would need to use only 2Ω main speakers and wire them in series. This is one reason I took R-F and Hawg-Wired (made by R-F) amps off my short list. I don't understand why they're designed like this, as most any modern amp has a range of acceptable impedances, usually 2-8Ω.

 

Not if you're using aftermarket speakers. It works well, & fits on top of the head unit. I even used the foam surround from the packaging to mount it to prevent unwanted vibration.

 

I see the rockford foz for $161 somewhere ,do a search.

 

My J&M amp and speakers was an easy install.
Follow directions - plug and play!
And if you have any trouble, John at J&M is ready to help!

 

bought a harness and amp out of a 08 SE ultra installed in a 2 hours in my 10 limited with detachable tour pack. left amp is in right bag. Sounds awesome and can hear the rear speakers great. PLUG and PLAY it is. Also all boom speakers and bass ports

 

i just ordered the RF 300 watt amp, RF 6.5s and adapters. Can't wait to install. A little concerned w/ routing power wire from batt. to amp...

 

As iclick mentioned, "plug and play" is a misnomer when referring to amp installations since you'll need to run a + wire of 10 ga. or so to the positive battery terminal with an in-line fuse close to the battery, and an equivalent wire to the ground stud under the seat or on the triple tree. Running the power and ground will require removing the tank or at least raising it for those wire runs.

I also disagree with Dr. V-Twin's reference to the J&M 500W amp being plug and play since you'll need to remove 1/2" or so of material from the plastic cups that secure the speedo and tach to the inner fairing, as well as using a cut-off wheel to remove a metal stud from a vertical fairing bracket per J&M's installation instructions. You can check-out the install instructions on J&M's website.

You need to decide if you want a two- or four- channel amp. Since you have an Ultra, you'll also probably need to relocate the CB module below the radio since most popular amps won't fit if mounted atop the module--Hawg-wired amps (at least some of them) will work without relocating the module; J&M amps include a bracket to relocate the module; and, 141Starlifter here sells a bracket to accomplish the same thing if you use the Arc 125.2 (or its clones), the Rockford Fosgate PBR 300X4 amp, and others. You can also secure the module to the bottom of the HK radio using industrial velcro.

You don't say what speakers you currently have. If you still use the OEM speakers, you won't get the improvement from simply adding an amp--the OEM speakers are a weak link.

A lot of folks are very happy using the Hogtunes Ultra kit (modest amp driving the fairing speakers only) or their other Ultra kit that uses a larger amp to drive all four speakers.

If you have the skill to remove an outer fairing, and run the power and ground wires, you have the skill to identify the speaker wires necessary to supply the wiring for the amp's inputs and outputs and make the necessary splices to install a two or four channel amp.

Good luck with your project.

I had no problem installing the Hog Tunes 160 watt 40.4 amp the only non plug and play item was the power cord. I also saved a lot of cash shopping on line. I ended up using Ride Shack for the customer service and great price.

I would check this forum for feedback on Ride Shack, including a recent thread. I bought my speakers from them and ended up paying $11 for shipping when free shipping was stated in the description. I was told I would be refunded but never was, and although $11 isn't a big deal it doesn't speak well for their CS, at least based on my experience. OTOH others have had similar trouble, but I will agree that their prices are very good.
