JL Audio HD1200/1 Car Monoblock Amplifier, 1200W 98250

Part Number 010-03170-00

Monoblock Class D Wide-Range Amplifier, 1200 W x 1 @ 1.5-4 Ω

Our most powerful HD amplifier employs our advanced Single-Cycle Control switching design and R.I.P.S. technology to deliver 1200 W of clean power into any impedance between 1.5 and 4 Ω, giving you the highest degree of flexibility in designing your subwoofer system. Tight power supply regulation keeps distortion down and maximizes your bass quality. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price.

While targeted primarily to subwoofer applications, the HD1200/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems.

This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.

Power Wiring & Fuse Requirements

For one HD1200/1, JL Audio specifies a 100A fuse on the main power feed near the battery. A generic 60A amplifier kit is not the correct recommendation for this amplifier.

• For a main power run longer than 72 inches (180 cm), use 2 AWG or 1/0 AWG pure copper wire, with a properly located distribution block reducing to 4 AWG near the amplifier.
• 4 AWG pure copper may be used for shorter main runs as described in the installation manual. Size a shared feed for the complete system, not this amplifier alone.
• Allow ventilation and clearance for wiring and controls; mount in a dry location. Wiring, fuse hardware and distribution components are sold separately.

Match the subwoofer wiring to the amplifier's rated 1.5–4Ω load range and set gain correctly. Use the JL Audio installation manual for the final power and grounding plan.
