Ok, heres the deal had this set up the P3 12" Phoenix Ryval 1000w mono amp in a similar box like the one in the pics, with a kinetic hc 600, it would only cut off after turning the volume around 27 on a Kenwood head unit, turn the deck off , turn it back on then it would play again until i turn it up to 27 depending on what kind of music i was listening 2 Example heavy bass music/mostly rap. could not turn up the gain on the amp either cuz it would cut off also
