I would recommend going to Americanhardbags website. Jesse or Logan with their tech support will walk you through it although the website has ton of material to setup your kit. Rob Gomez is actually the one who worked with Diamond Audio to put together the Kit you purchased. He also helped develop those horns. I dealt with Paul (702motoring guy) when I bought my MO75T horns but I ended up blowing one and he told me I had to run 8 ohms to them (????). Even Diamond audios box clearly calls out 4 ohms. I then saw the installs and knew very quickly I am never going to this guy again and I'm a Vegas local. I switched over to American hardbags and their tech support is incredible.

The install is easy and I used a small aukuyee oscilloscope from amazon to set the gain. you can do it by ear. American hardbags will tell you to use Michael Jacksons Billie Jean. 702 guy will tell you to use 'the ghetto' by too short. I have a similar system setup on mine except I use the NEO 6.5 from Diamond and am sending them bridged power with a diamond/Cerwin 6 channel amp. Let me know of q's. I would recommend a dsr1. I added one later and should have done it sooner. It allows you to get rid of the frequency spike you see with Harley radios plus fine tune your system. I got mine from American hardbags and Rob programmed it for my setup so it sounded great out of the box. I did some minor tuning. super easy to use
