two channels stopped working just two days past return date. contacted Amazon to do an exchange. What a nightmare. Orion sent me a new email asking question's for three straight days . Finally after that I was emailed a UPS tag and item return number. After Orion had the amp in there hands for over 20 days I sent and email to customer support with all tracking and return numbers looking for a return date. received no response. Contacted Amazon support to see if they could help. All Amazon could do was summit a report to Orion. Not vary helpful.After Orion had the amp in there hands for 30 days I recieved a email with a tracking number from Orion. No other info.They sent me back a amp that was covered in black smoke and dirty finger prints. Not mine! The amp smelled like a wire fire really bad. Now my truck smells like a wire fire.Vary disappointed in this entire experience. Orion sucks.
