Anyone has tried or used this amp before? As I search through google, I find its spec is different from normal amp spec for car audio

. Stereo @ 4 Ohms 4 x 75W
. Stereo @ 2 Ohms 4 x 150W
. Bridged @ 4 Ohms 2 x 260W
. Crossover 40 - 400Hz
15 - 400Hz

. Bass EQ @ 45Hz 0 - 12dB
. Input Sensitivity Hi 0.4 - 8V
Lo 0.2 - 4V

. S/N Ratio > 90dB
. Separation @1KHz > 60dB
. Damping Factor > 200
. Idle Current < 2A
. Input Impedance > 20k ohm
. Dimensions 472 x 60 x 234 mm
. Weights 6.48kg
. T.H.D. < 0.05%

20 - 60kHz

As normal amp for car audio which I know off, the specs alway put as RMS power output @ 4 Ohm , but this Rangers put Stereo.

Is it really suitable for Car audio or only for home audio?
Anyone can enlighten me? Thank you.

Cheers!
