Some asshat on the FJ Cruiser forum is bashing the Xenon line. Quote from said asshat "actually they werent a very good amp. they were known to not have a flat frequency response."
So anybody care to help me out here?
Linky to thread
Anyone have a frequency response graph for a Xenon amp?
What. The amps don't play flat? Why don't you check where HE got HIS information from first? That's the stupidest shit I've ever heard 
Throw a couple of these at him first... There are frequency response curves for the Zapco and X100.2. Both amps have a whopping 0.5 decibel difference at 20Hz. Totally audible!
