Hey, check all your wiring to ensure everything is tight including power and ground wires. Had one customer that their wires were lose on their capacitor and their JL Audio 1000/1 was too hot to touch. Like Lanning said, ensure they have enough room to breath. Make sure you have atleast true 4 gauge running to the back and true 8 gauge to the amps. Also, at they V1 amps or V2? V1 JL Audio amps had an issue running hot.
