The Official 2014 audio upgrade thread
yes the J&M amp kits are all plug-n-play, but the J&M pricing is not for everyone ,,,,,,,,
Regardless of which brand of amp you choose ,,,, the principles are the same ,,,,,,,,
you need to come out of the Harley radio speaker wires ,,,,,, reduce and modify the audio signal into the RCAs of whichever amp you are using, and then put it back out to the speakers ,,,,,,
the "magic box" is a decent idea, but you can do the same thing with the controls on most amplifiers including J&Ms ,,,,,,,,
it would be easy for me to be offended with a lot of what is posted here, but it is really OK ,,,, after all these years I do just let it roll off ,,,,,,,
if you like the product and service that J&M offers, then buy it and send an email to me direct for a good promo code when you are ready ,,, john@jmcorp.com ,,,,,,,
if you find something that you believe gives you better performance for the $$$ spent ,,, then go for it, that is the beauty of living here in the good o'l USA ,,, we all have choices ,,,,,,
please let me know any time that I can be of assistance to any of you ,,,,,,

JM I believe has end to end solutions that are plug n play without splicing, the JM amps last I checked were rebranded Arc Audio amps which are regularly touted as some of the best in the industry, if I'm wrong on the arc audio thing someone will correct me I'm sure it's been a few years.
Biketronics isn't plug and play out of the box, but others sell just the adapters so you could use those to make it that way.

not sure why your having problems with this set up. maybe your magic box is defective?
have you tried getting your HU flashed with the amp installed ?

It is very simple to mount the the speakers "on top" of the box just like the stock speakers. The speaker mount tabs line right up with the stock location. Just attach the stock speaker wires to the speaker terminals observing polarity (your colored wire with the black stripe goes to the - terminal, the solid colored wire to the + terminal). Then attach the speaker to the box with 4 screws.
Assemble the speaker box together and turn on the radio to check it before mounting them to the fairing. Leave the grills off.
If that works then take the speaker wire from the radio and connect them to the magic box input. The output of the magic box goes to the amp. inputs. Remember the amp has 2 identical 4 pin connectors. Set the gain (small rotary switch on the side) to 7 or 8.
