My amp started freaking out yesterday. Kept cutting in and out. I checked the ground today. It was a little corroded so I cleaned it up and put some anti-corrosion gel on it and it seemed to work fine again. I was on my way home from work tonight and it cut out again, but stayed off this time. Checked the ground again when I got home, but it looked fine. Power cable is good too. Any suggestions on what my next step should be?
