Rockford Fosgate R300X4 Prime 4-Channel Amplifier

hi victory stereobuff here today i have a new school rockford fosgate prime r300x4 it's a four channel amp that's 300 watts total it's ready to put out two times 50 watts into four ohms or four times 50 watts into 4 ohms or 4 times 75 watts into 2 ohms or you can bridge it for 2 channels at 150 into four ohms those are all one percent and the ratings are made at 14.4 volts so well i i got hooked up to some load resistors and oscilloscope and i can only use the battery voltage to 12.8 so i probably won't get as high in numbers and i'm going to measure the distortion with this meter this light right here and the power reading i'll get on this am1 i'll set it for dyno power and you can look at the sine wave on the oscilloscope right here and maybe what i'll do is turn the charger in so they can keep trying to keep the voltage up let it go up a little bit and i'm going to run a 40 hertz con
