Aquatic AV + Boom! Bagger Kit
I have a 2009 Street Glide with the Harmon Kardon Boom! bagger speaker kit. I bought an Aquatic AV head unit to replace the stock unit. I have the unit replaced and powered on, but cannot figure out how to get sound working. I know the unit is working properly by hooking speakers direct to the rear stereo outputs. I know I'm missing something with splicing the harnesses but I can't find any pinouts of the harness for the amp. There must be a need to splice a turn-on lead for the amp/etc. There's no sound for the front speakers either.
Amp: 76000071
Boom! Bagger Kit: 76000074
Harness: 69200106
Any help is greatly appreciated!!

You cannot use any aftermarket head units with the Harley branded amps. They are powered on by a CAN-BUS signal that is not present on your aftermarket head unit. You will have to rip out that Boom amp and go with an aftermarket amp and speakers, or at least an aftermarket amp that will work with two ohm speakers which is what you have.
I'll warn you though get new speakers as well. Most aftermarket amps will blow those Boom speakers in short order. You will need to get a set of cheap 5 1/4" to 6.5" speaker adapters as well if you replace the speakers. If you do all that you will be blown away by the improvement.

Thanks @Hoyt 1911A1 that was what I was afraid of. I didn't realize I had the HD amp (previous owner had HD install it) and was debating buying the Rockford Fosgate 4channel amp. I did already buy the TMS6SG speakers for the front to pair with the new head unit. Guess it's time to pony up for the amp and rear speakers now. First world problems.
Thanks again for the quick reply. Saved me from ripping out more hair

I would suspect that you would just run new speaker wires from the amp to your speakers. That's what I did with my 2010 Ultra Classic. I have the amp mounted on top of the head unit (fed by preamp outputs from the head unit) and new generic 16 gauge speaker wires running to my aftermarket speakers in the fairing. All the factory wiring is still in place in case it ever needs to be put back.

I'm sorry I didn't clarify. You should be able to keep the radio plugged into the original stock harness for power and handlebar control and use the preamp outputs from the head unit to supply an audio input to the aftermarket amp. You will need to run eight gauge power and ground wires to your battery to feed whatever aftermarket amp you wish to use. Then come from the amp with new speaker wires to the speakers.
If I am remembering correctly you would not need that accessory harness you bought at all unless you have additional modules connected to the head unit like CB/NAV/iPod.
I am assuming you should have at least one set of RCA preamp outputs on your Aquatic AV head unit to use. What model head unit did you buy?

That one should have two sets of four volt preamp outputs to use with an amplifier. If you wanted to get a set of lowers and put speakers in them you could get a four channel amp like the Stinger 700 and put the lowers on the rear of the fader control so you could blend them properly with the fairing speakers.
