I have a 2010 tundra with the factory deck. When I use the dd1 distortion detector it distorts at volume 25 Max volume on deck is 62 I can barely hear the mid and highs if I set the volume at 25. This was using the dd1 with RCA from the deck and off the amp. Running a kicker zx1000 for sub and using all factory deck mid and highs.
Thanks
