I love mine too and have to agree with the sentiments above. It's very easy to install. I was apprehensive about piecing together a system myself or getting all the wiring right for for a system with various parts. I'm sure it's simple to some but it was intimidating enough that in wold have had it installed professionally. The NL PPP was easy enough with literally two wires (red to red, black to black) that the additional cost for the PPP was a cheaper alternative versus the cost of professional installation.
