Already burned 2 head units need help

[gizmo1]

Should be cool. All the headunits I've been through I've never burned one up. I've had a pioneer that the rcas went out on me once though. And a flip out soundstream that was a complete piece the volume knob quit working and I had to use the remote. Then it eventually quit playing disks all together. It was under warranty still but the company would never reply to any emails I sent. Was a legit company too but they got shady on me.
