after market amp wiring

1. Red= 12V constant from the battery
2. Black= Ground (I came from the battery as well)
3. Blue= Remote turn on from head unit. (This turns amp on after radio is on)
On the Arc amp, there are no actual wires, instead there are slots with allen head screws where you place the wire in and screw them down.
There are also RCA cables that need to be hooked up to the head unit from the amp. My Alpine has front, rear, and subwoofer RCA's, but on a factory head unit, I believe you have to go a different route. I know there is a plug with four wires (I believe) that comes with the amp and I believe you have to use that because the factory head unit has no RCA's. I could be wrong since I have never seen the back of a factory head unit in person, but from what I have seen online, there is no RCA jacks on the HK radio.
That's it! I've never had a Harley, much less ever worked on one, but I got it done. It wasn't that hard. The hardest part for me was having to work in such small areas behind the fairing. Just take your time like I did. There was no rush for me.
As for mounting, I used some industrial velcro I had laying around. Placed it on the bottom of the amp and stuck it to the top of the radio. After that, I took a very large zip tie and strapped it down even further. I know with the velcro it won't be going anywhere, but I zip tied it anyways.
Good luck!
