SounDigital 800.4 evo 4 mini car audio four channel amp dyno power test #caraudio #ampdyno

This video features a four channel amplifier made by SounDigital. The model is 800.4 evo 4. The amp has been tested for continous power with a 1kHz and 50Hz sinewave test signal. I also check amplifiers for dynamic headroom with a 1kHz burst signal of 20 cycles, that means 20ms on and 480ms reduced by 20 dB which represents the IHF-202 standard to test dynamic power. I also include efficiency tests. Check out the amplifier power test result sheet !
