i have 2 orion hcca15s and 2 orion XTR2500.1dz amps. One amp no matter which sub its hooked up to will cause the sub to play without any music on. It thumps every 3 or 4 seconds like it’s on beat with something but thats all I get. When I unhooked the speaker from the box, I kept getting sparks while testing each sub. Both amps are powered and grounded directly to my batteries in the trunk. Wiring all seems good, does it with RCAs unplugged, at this point I assume it’s a bad amp?
