Very clean, Powerful, Crossover options

I like the look of the Gold plated internal of the Zx450 better

This the best amp I have ever owned. It very clean powerful. I used ot a pheonix gold Zx450 (sepreates/Rear fill) Zx350 (Subs), I remove the rear fill (waste in a convertible) and used the rear channel of the Zx475 to run the subs. I was pleasantly surprised that the Zx475 less powerful 75x2 didn't miss a beat vs the 100watts output of the Zx350.
