I have a 2015 Road Glide Special. I bought a Rockford Fosgate PBR300x2 amp. I bought power/ground/fuse. What do I need to actually hook my amp to the head unit though? Note: I do not want to cut or tap into any factory wiring if not absolutely necessary (for warranty concerns). Thanks in advance for the help.

If you buy the magic box you will not have to cut into any wires the magic box plugs into the speaker leads coming from head unit RCA'S too the amp.works slick also eliminates The need for dealer flash.

You can buy harness like these: VTFSA14, 2014 & Up Harley Ft Spk Wire Interface, Street Glides & 2015 & Up Road Glides | Motorcycle Audio Accessories | V-Twin Audio & More

I have nothing to do with v-twin audio....Others make harness too

Or buy the Molex connector/pin/wire and do your own ....

Believe it or not... you can make your own connections to the factory speaker harness with spade connectors...an they work great with the correct size ( which I cannot tell you... sorry ) ,, if you go this route you will need to flash the HU via Digital Technician at your dealer for around $40

So if I buy the magic box is that all I will need to install amp and speakers? Or does that just cover the amp?

 

[dozer23]

Magic box is a signal connection and filter. You will still need to splice wires from amp to speakers,power, ground and remote turn on.

Your right about the volume level at 80% and not much more volume. The amp will take care of that. The reason I started this thread was to show them another option besides the usual. I think for only using the head unit, they are a big improvement over stock. 3 Way Loudspeakers are great. Just my opinion.

Lemme know if you find a reasonably priced amp to match up to these bro. That should surely help. I was just disappointed in the amount of improvement so far from stock. Must be the "sum of the parts" kind of deal in my case. Windshield should help as well I am sure.

Went to Home Depot and bought 2 five foot, 8 gage red and black wires and added a fuse block for a 40 amp fuse for the power wire. I'm only running the 2 fairing speakers, so I'm using the front portion of the amp, will use the rear portion of the amp at a later date for bag lid speakers. Unplugged the speaker connections and connected the input wires from the amp to the speaker connection from the head unit. Then connected the speakers the amp. Had to adjust the gain on the amp to just under half and switched the crossover switch to HP 80HZ. If you go this route, I think you will happy with the out come...I am! I hope this helps.
I installed the same amp. You're correct, it's really tight, but it does fit. I took the 2 bolts out that hold the radio mount to the inner fairing. I was able to flex the inner fairing enough enough to drop the HU back in. All I could find was a 30 amp inline fuse holder. It works fine. I'd rather take the seat off to replace a 30 amp fuse, than pull the fairing to replace the 40 amp fuse in the amp. I connected the remote wire to the powerport/cigarette lighter. I grounded the amp to to the upper crashbar bolt. I cut the connectors off the OEM speaker leads, and connected the wires to the supplied input pigtail. I reused the OEM speaker connectors on the new speaker output leads. I connected the pigtail ground to a bolt inside the fairing. the amp got zip tied under the OEM HU bracket.
I have no flash or line leveler, (magic box) and no plans to add one in the near future. I have the AVC off, and the bass & treble turned down 3 bars. Occasionally, a track on my playlist will distort, and I will either turn down the volume or advance to the next track. I suspect the tracks themselves are responsible. I was pulling a steep grade today @ 70 mph and could hear the music clearly. I'm running Cobra Powerport headers and Khrome Werks SS mufflers.
I am in no way, an audiophile, but this is a huge improvement. For $59 (speakers) & $106 (amp) I don't see how you can go wrong.

Magic box is a signal connection and filter. You will still need to splice wires from amp to speakers,power, ground and remote turn on.

I just installed focal speakers I had from another project.
I ordered my amp and "magic box" from cycle sounds.
I also installed a line booster as the box can reduce the signal to the amp. (Peripheral/PAC LD10 Line Driver Signal Booster). from amazon.
this connects between the magic box and the amp.
I mounted the amp under the radio.
Cycle sounds has adapters to plug in to the stock speaker in/outs.
I did not cut any wires and took my acc power from the aux plug.

I have had some really nice systems in my other bikes but I just don't want to spend thousands this time.

This set up works with the stock windshield at 80 mph on the interstate.
FM still works good. has some wash out but not near as bad as stock.
I did NOT have any flash done to my radio.

Thanks Festus, I appreciate the info man. Will be following suit with what you have done wiring wise. I will post some pics up after I am done. I am hoping that I can give guys a great option for speaker/amp upgrade for under 1,000.

 

[Q-Hog]

Good info. I'm might start this mod next month. I've been holding it off all year.

Lees than $1000?
I paid 319 for the cycle sounds amp, box, amp power kit, speaker adapter kit (wires with stock plugs).
22 bucks for the signal line amp.
thats 341 bucks.
I had the speakers but you can get some nice 6.5's for 100 bucks or less. Mine fit right in the stock location.
thats less than 500 and no dicking around with any downloads.
I also used heat shrink on my rca connections.
I would have preferred a hawg wired amp but I wanted to make sure the magic box worked. I am going to run this for a while and will add lower speakers this winter.

I do have hog tunes speaker grills that were 50 bucks BUT they don't count. Stock grills should have stayed on some kids little tyke toy!

Good luck guys as I said I am pretty happy with my stereo now, probably about where it should have been stock.

 

[Shaner87]

Well my speakers alone were 450 for the jl c5-650x. Rockford Fosgate pbr300x2 was 150. Wiring was 60. Ordered magic box and speaker plug adapters for 100. So right around 800 for mine.

 

[dozer23]

Why do you need speaker plug adapters you have to splice into the amp.and make speaker ends? (Right)

 

[Shaner87]

I was hoping to tap into those instead of factory writing... I dunno if its going to work or not though. Worth a shot.
