I luckily got my Arealth 9 channel on sale for Black Friday. I watched the install videos on the YouTube several times and followed along step by step during the install which I did myself and didn't take to a stereo shop. Everything is clearly labeled and provided in the kit. A long as you can work an impact gun, razor blade, drill, and trim tool, it literally is 11 connections to make. I've never installed a stereo system before, but in two days, I had the very best system I've ever heard. Highly recommend these guys! I I did have to call in a few times for questions needing answered and they always answered them and walked me through.
