I Have 2 Zv5 18’s & I Was Just Testing Them On A 3k Tramaps 1 Ohm . One At A Time Not Both To 3k . All I Get Is A Pop/Spark Under The Cone When I Turn It Up & Protection Mode. When I Run My 2 12’s Sa Sundowns They Run Fine On The 3k . Is it a coil problem. Or is it because I wired a 2 ohm amp to a 1 ohm sub I know I’m not supposed to do that but it shouldn’t pop should it ?
