I have a class A/B 800W RMS, Zeus Series 2-Channel Amplifier (ZXi 200.2) and from the moment it arrived on my doorstep it was broken i had to send it back to sonicelectronix and they claimed it was not broken and had only been bench tested yet the warranty seals were broken so obviously they fixed it charging me a shipping fee and voiding the warranty on it. the amplifier broke again and its the same problem everything works except it makes no sound. I'm pretty sure the problem is on the circuit board because the amp got really hot then stopped making sound. the power light still lights up but dimly and the blue Hifonics symbol still lights up. what could the problem be and how could i fix it?
