This a great amp for my 2014 Harley Davidson Ultra Limited...I am extremely satisfied with the performance that I purchase two of these amps, one for the front speakers and one for the tour pack rear speakers...pared with an infinity kappa 62 11i it sounds great & priced reasonable compared with the more other third party amps, most especially Harley's boom amp.

A snap to install on the Harley. Just give it power and put it in line to the speakers. No need to run a remote wire, cut or splice existing wires, or anything else. Works great with boom audio speakers. Also consider upgrading to 6.5" speakers.

I recommend the following materials:
Heat Shrink tubes
3 Feet 16GA speaker wire to run from the amp to the speakers
1/4" and 3/16" quick disconnect male and female plugs. for connecting existing speaker wires and speakers without cutting original factory wires.
6 feet of 10-12Ga red power wire. Run under the chrome trim on top of the gas tank.
2 feet of 10-12Ga black ground wire. Run to the frame.
30Amp fuse and fuse holder. Near battery use buttconnector to your power wire and on the other end use round solderless terminal to battery.
Butt connectors
Round solderless terminal
Double stick tape to hold it ontop of the exisitng radio. The amp will fit in any direction.
Make sure you use a proper crimp tool. Pliers will not work well.

this small little amp pushes with excellent sound 4 Lanzar 200 watt speakers with no problem. had to wire with high input instead of RCA's. Very Happy!!! Can hear it clear as if you were sitting right next to it from a block away

Installed on my 2016 Road Glide, I looked around did my research and found this to be the best bang for the buck. This fit right under stock radio after you pull headlight out, I did replace the stock speakers also with Polk's, I didn't want to spend the big money for Focal's or Hertz speakers.

As you know the stock system on the 2015-16 Harley STUCK. I could hear about 45mph and that's with a taller shield, replaced the speakers better but still not where it should be.

Install this amp in your Glide you won't be sorry.

After adjusting the gain I can't believe how loud and clear it is with just the two front speakers, and I was thinking about getting the four channel sister amp because I thought about installing bag speaker at sometime, I really don't think I need rear speakers...

I reviewed some videos on how to take fairing off and there was one about installing a kenwood amp and he spliced into a wire to get power which is probably fine, but the instructions on this amp suggested to run a power wire straight from the battery which I did, I did find a switched 12v not being used and was able to spliced that for the amp remote, it took me probably four hours to do this project. I ran new speaker wire though the stock grommets also, heat shrank all connectors, wire tied everything neat, running the wires to the battery is a pain I had a fish tape so that helped after taking the two tank bolts out and propping up the tank.

Oh one other thing I did buy was a DSP line-level shifter (Magic Box), which from what I've read you need on the newer Harley systems, worked out good no spicing of the stock unit speak connectors.

So the speakers were $135, Amp $152, Magic box $70= $357 cheaper than upgrading through Harley and I can't imagine it sounding near as good....

Hope this helps everybody on 2015-16 Glides..

outstanding little amp,, can hide anywhere on a harley bagger,, the sound is mindblowingly louder.. I bought the boom amp for my bike and for 400 dollars it was a joke compared to the fosgate,, and bigger to boot..

I'm not really an expert on amps because my current setup is the first time I've ever attempted to upgrade my truck's audio with new amplifiers. What I can say is that this device puts out far more volume than I could handle if I allowed it to do so. The audio sounds very clean to me too.

I was not interested in blasting ghettos or "impressing" people in other vehicles with my audio system. I only wanted to have nice, clean, loud sound and that's exactly what this amp provides. Space in my vehicle was limited so this thing's tiny size is a great benefit since I wanted all of this stuff to be hidden.

If I had to mention any minor complaints it would be the manner by which wires are connected because I'd have preferred more standardized plugs and 4 gauge power/ground connections, but this is a minor complaint.

My main complaint is that the thing gets hot. Very hot. I can't help but wonder if the daily fluxuation from intense heat to cold will damage the internal components after a while. I would not recommend placing this directly against carpet and on mine I mounted it to a piece of diamond-plate aluminum with washers lifting it from the plate. This allows air to circulate around the entire device and allows the plate to act as a big heat sink.

Installed on my 2012 Harley Ultra. Amp Works Great and I'm Very Happy with this Amp. I also purchased after reading the installation directions the Installation kit just for Harleys. The Amp requires a 8 guage positive direct to the battery and all the speakers need extensive wiring to boot. just seemed easyer to buy the harness pre made in this case. the mounting plate for the amp attaches to the top of the radio and is easy to install BUT!! This require you to remove your CB/Com system with No New Place to install it and the directions don't offer any information of any kind about the delama rockford created.. Poor Something going on here to just forget or avoid a major part of the system installation while desiging a install kit. I just double sided taped it to the top of the amp. Hope the heat gets out properly and the amp holds up. rockford doubles the amp warranty of you use the install kit. we shall see. Note: The box does say that this kit is for my 2012 HD Ultra Classic FLHTCUI. CB/COM system is standard equipment
