Ya, they don't know what's going on either. Just keep having me try different things. It worked fine for a few months.. little finicky but nothing crazy. It just doesn't feel like a well made or stable device. Trying to find alternatives. Might go with jl audio and audio control. Hopefully Monday I'll know which one worked as a replacement. FingersSuper weird. I've had mine running since January with no problems. I'm running the axxess dsp into a Kenwood 5 channel. Morels front and Rear and Kicker sub. The only Problem I've ever had is that at super high volume I get breakup, but honestly I think its cause I'm pushing the amp too hard. Have you called metra?
Ya, maybe you are clipping somewhere., either HU or amp. I went a little crazy with my setup... :/ been a headache since I started in Oct.
