Im about to tackle the project of installing this amp on 15 road glide on Friday and after a bunch of reading and searching I think I have most of the plans and process nailed down. I’ve already installed Hertz hcx 165’s in the fairing using biketronics spacers and hog tunes grills and will be using their line leveler to wire the amp.

Question is about the REM power. I have the power lines with inline fuse from previous amp on old bike that’s 8 gauge and should be fine I think. I didn’t find anything in the instructions saying what gauge to use for the REM power that turns amp off when bike shuts down. I have some 18 gauge wire and weather proof quick splices that I was going to use to tie the rem power into either the headlamp or cigarette lighter power wire. Will this be sufficient?

Also if someone could chime in on mounting location that would be great. Plan as of now is to mount it above the headlight housing securing it in this area with Velcro and maybe zip ties. Is it absolutely necessary to shave off the tabs at top of the housing where wiring harnesses are currently attached and if not how did you go about getting it to fit? Keeping in mind that any type of metal fab is not in my wheelhouse at all.

Thanks in advance for any help you can provide,
