Review on PAC LP5 4 4 Channel Output Converter by Sean Davis

Well I bought one of these a few weeks ago and had it installed at a professional stereo shop. Because I couldn't because there was fiber optic cable running from the factory radio. So one of my on-site specialists connected it. It connected well, the problem was only distortion came out because the cable was a little loose and couldn't stay there properly. And I couldn't find the right tune. So I got another one to replace this one. Now all I hear from her is a high pitched sound, like a whistle, and it's really annoying. It goes away when I turn on the radio, but I still have distortion. So I will have to send it back. So don't waste your money, it's garbage. See, I'm an experienced installer myself and have a degree in electronics. And I have to say it sucks really badly
