JL Audio HD900/5

Free High-Quality Power kit with any HD series Amplifier!

 5-Channel Class D System Amplifier, 100 W x 4 + 500 W x 1 Guaranteed 11.5V - 14.4V

Thanks to its ability to act as a "one-box solution", the HD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.

While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system... with a very serious 900 watts of power!

Using our Single Cycle Control switching design and R.I.P.S. technology, the HD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500 W to its subwoofer channel. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound 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.

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.

R.I.P.S. (Regulated, Intelligent Power Supply)

R.I.P.S. – Regulated, Intelligent Power Supply

Summary:
The remarkable R.I.P.S. System ensures consistent power delivery over a wide range of battery voltages and load impedances.

Detailed Information:
R.I.P.S. stands for "Regulated, Intelligent Power Supply" and is a central feature of JL Audio's 'Slash' and HD amplifiers.

"Regulated" means that the power supply adjusts its operation so as to maintain the amplifier's rated power output and low distortion operation over a wide range of vehicle voltages (11V-14.5 V). This contrasts with conventional, "unregulated" power supplies, which allow rail voltages to sag in direct proportion to drops in the supply voltage. This can result in significant power losses when battery voltage decreases, even if those voltage dips are short in duration. This manifests itself audibly as increased distortion. With a JL Audio R.I.P.S.-equipped amplifier, the rail voltage and clean power output remain completely stable in real-world systems, resulting in superior fidelity and stability.

The "Intelligent" portion of the R.I.P.S. System is a circuit that actually monitors output current to optimize the amplifier's output power over a wide range of load impedances (1.5 ohm to 4 ohm per channel).

Conventional amplifiers are designed to produce optimum power at a particular impedance (2 ohms, for example). When asked to run above that impedance (say, 4 ohms), these amplifiers lose power (half their power from 2 ohms to 4 ohms). This will not happen with a JL Audio HD or 'Slash' amplifier because the R.I.P.S. System detects the actual impedance being driven and adjusts the amplifier's operation to deliver optimum output. The entire process is seamless, automatic, and results in incredible dynamics for satellite channels and consistent power output for a wide range of subwoofer configurations. It also takes into account the real impedance of the system, rather than relying on often inaccurate assumptions based on a speaker's rated impedance.

The bottom line: Optimum power, at any impedance between 1.5 ohm and 4 ohm per channel, at any vehicle voltage between 11.5V and 14.4V.
