Worked great for about 11 months.

Bought Aug. 2017 installed Sept. worked great for about 11 months. This morning one of my speakers blew and it seems like now my amp is stuck in protection mode even with no speakers or RCAs cables hooked up. I unplugged it, took out of car and it definitely has a burnt smell to it so something got fried inside. Disappointed because I really like the performance it put out but didn’t last at all. I wish I bought the 2 year protection plan...
