Let me begin this by saying that I do not believe that JL Audio is a scammer and I would definitely buy from him again, but he recommended I make this thread so I am. I bought an RE 12.1 via payments from him a few weeks ago and had not had the chance to test it until recently. Once hooked up it would run just fine until ~18 out of 35 on a Kenwood X397 with the subwoofer level, bass, gain, everything turned all the way down and then it would kick into protect. I thought the subwoofer may have a blown coil so I checked those with a DMM and they checked out just fine. I thought I may have voltage issues so I checked those and they also checked out a-okay. I tried another sub completely and it still did it. In the end I went to a shop and switched it for a T1000 to test and the T1000 worked without issue on the exact same setup. So I had isolated it was the amp and not my car or subs. I then texted JL Audio informing him of the situation and he has since offered a refund by Thursday or Friday. He was extremely apologetic and I'm happy to say I don't expect any issues. Just a bad amp. As I said, I made this thread only because he recommended I do. He's a fantastic seller so far and I would definitely buy from him again. I will update this when I get my refund. Sorry for the novel all, I just wanted to be detailed.
