Our take on the JL Audio HD Stacking Kit

Build your tower of power with JL Audio's expandable stacking kit for multiple HD Series amplifiers. The kit contains mounting screws that conceal behind your amp's corner caps, and you can stack amps with or without the mounting feet that are included with your HD amp. You'll find enough spacers to stack two HD Series amplifiers and you can purchase a second kit to stack additional amps. Warranty: 30 days

Thoughtfully designed, seamless execution.
