Hello,
I have an MRV-500 from alpine that ive had for a few years decided today i wanted to retune my amp since I haven't done it for a while and it was sounding odd.
I set head unit to max volume (doesn't clip I checked with oscilloscope) and played a -5db 40hz tone. I was amazed how much disortion and clipping there was as I was measuring the outputs with scope. I had to turn the gain down to 1/4 to get rid of all visible distortion to the sin wave.
This seems really low to me... Could the amp be damaged? Input preamp was 6V. Didn't remember the output voltage.
Thanks for the help!
