Im not trying to hate, because from my small cell phone pics it looks like a pretty decent install, but you couldn't pay me to run a single one of those brands. What is your goal with it...i.e. have you ever ran good audio, or are you just trying to get as loud as you can for as little as you can?
That aside, while it isn't my style of install, I applaud your DIY skills...they are above most of what I see on here, and you're not even using t-shirts or old kitchen tables.
