About this product

HD_STACK_KIT Amplifier Stacking Hardware Kit for JL Audio HD and MHD Amplifiers This hardware kit allows you to stack one HD or MHD amplifier onto another. By using multiple kits, it is possible to stack multiple HD and MHD amps. The kit includes four specifically engineered mating bolts, and four threaded, alloy stacking caps.

Installation tips

  • Size power and ground wire to the amp's current draw and fuse it within 18 inches of the battery.
  • Keep the ground short (under 18 inches) to bare metal on the chassis.
  • Set gains with test tones or an oscilloscope — the gain knob is not a volume knob.
  • Mount it where it can breathe; amplifiers need airflow to stay cool.
