I just got mine installed. Had absolutely no idea what I was doing but everything appears to be working. Obviously I still have some wiring to tuck away and covers to install but then I'll be done.
Sounds nice and powerful but this was probably a little bit of overkill for what I needed. I just wanted to add a little kick to my country although my wife likes to shake the windows

I don't know a lot of about adjusting settings on a sub but hopefully I'll be able to dial this thing in to give the sound I want. I have a couple of rattles in the car I'll have to address but I'm happy with the quality of this system. I can't believe it all fit into the trunk as nicely as it did. I'm definitively glad I didn't wast my time on a two sub box as I cannot imagine ever needed more bass that this.
