Review on Hifonics ZS525CX Zeus Coaxial Car Speakers (Black, Pair) – 5.25 Inch 2-Way Car Audio Speakers, 200 Watt, Passive Crossover, Sound System with Grills Included by Christopher Buck

I have used them to replace a camper audio system and they have certainly improved the sound quality tenfold. I'm an old school car sound dude from the 90's. So in the past I've spent thousands of dollars on old Zeus and Colassis amps and it's been a while but in the past the name has served me well so I paid them back. FYI I gave these amps to my nephew a few years ago while cleaning out the garage. Three weeks later my brother called the Sand Uplift because he could hear my nephew before he even got home. LOVE IT!
