Do you have DSP? My stupid ass mechanic took out my dsp amp becuase the battery kept dying. He said "the battery was dying so we replaced the battery. When it died again, we figured it was the amp becuase it was making a noise and the radio was crackly." No that he doesn't have the car anymore, I will check the above as well. If he got that wrong too, I can't wat to have my attorney write him a letter.
