5-channel powerhouse

The Alpine PDX-V9 5-channel amp delivers a whopping 100 watts RMS each to four speakers at the same time it blasts 500 watts RMS to your sub setup. This amazingly compact amp uses beefy internal components and clever engineering to keep the power output strong and the noise low for superb fidelity and control. The adjustable crossovers feature an extended range of crossover points, allowing you to use this amp with component tweeters, midrange speakers, or midbass drivers.

They make a cool stack of amps

Alpine packs Class-D amplifier technology into this PDX amplifier for awesome power from a 2" tall frame. This small-but-mighty amp runs so cool that you can stack it together with other PDX amps into a single unit — the multiple heatsinks actually couple together to cool the entire stack. Each PDX Series amp offers the same 8" by 10" footprint, so they'll fit in hatchbacks, trunks, truck cabs, and any vehicles with limited space.

Front-mounted controls and pop-out connectors

Front-mounted controls make post-installation adjustments a snap, even when multiple amps are stacked together. Nifty removable speaker and power wire plugs make it easy to install or remove an amp, ensuring a tight connection while guaranteeing that your speakers work in unison. Gold-plated RCA inputs, outputs, and power connections resist corrosion and signal degradation.

Features

PDX Amplifier Design: Class-D amplifiers boast higher efficiency, produce much less heat, and draw less current than traditional Class-AB amps. The PDX series is Alpine's super-efficient power density design of full-range and monoblock Class-D amps. They combine MOSFET power supplies, MOSFET final outputs, and a thermal management processor, along with a 6-Layer Glass Epoxy PC Board to create a high-end sound quality without the bulky heat sinks required by most amps with this much power.

STAR Topology: Alpine's unique STAR (Signal Transit for Accurate Response) Circuit PCB design provides a single common ground for all amp sub-blocks, preventing ground interference and minimizing internal noise.

Power Management Processor: The Alpine PDX amplifier incorporates Alpine's new Power Management circuit. The Power Management Processor controls all aspects of amplifier performance, monitoring voltage, temperature and output to ensure uninterrupted power output for non-stop listening.

Uninterrupted Protection Circuits: If the amplifier gets too hot, the Thermal Protection circuit kicks in and gradually decreases output power until it cools down. Once cool, the power output automatically increases back to the previous level. If the circuit detects a Low Battery condition, it will gradually decrease power output if battery voltage becomes too low. Once the battery voltage increases, power will be restored. This interruption-free design allows for non-stop enjoyment with no hiccups or drop-outs, just clean, clear output.

Channel Design: The Alpine PDX-V9 can be configured as a 5-channel, 4-channel, or 3-channel amplifier. The amplifier is stable down to 2-ohms in stereo, and 4-ohms when bridged.

Low Impedance Stability: This amp is stable at low impedances and is capable of its rated power (100 Watts x 4 + 500 Watts x 1) from 2 to 4 ohms. This allows excellent flexibility with multiple speaker and subwoofer loads and is adjusted automatically.

CEA 2006 Compliant: The PDX-V9's power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging.

  • 4 Ohms: 100 watts RMS x 4 and 500 watts x 1 @ 14.4 Volts with <1% THD+N
  • 2 Ohms: 100 watts RMS x 4 and 500 watts x 1 @ 14.4 Volts with <1% THD+N
  • Bridged (4-ohm): 200 watts RMS x 2 @ 14.4 Volts with <1% THD+N

Verification Certificate: The amplifier comes with a certificate that lists the RMS power output of the individual amplifier. It also lists the model number, serial number, test date, and the test conditions (14.4 volts, 4 ohms).

Ultra-Wide Frequency Response: The Alpine PDX-V9 offers a super-wide, frequency range (5Hz-50kHz, +0/-1dB) for unparallel sound quality and detail.

Ultra-Low Output Impedance: With ultra-low output impedance, the PDX-V9 offers extremely controlled, tight bass for unprecedented sound quality. The amplifier's Damping Factor is rated at >500 for channels 1-4 and >1000 for channel 5.

High Signal-to-Noise: This amplifier is capable of S/N ratios up to 92dB S/N at 1W and 112dB S/N at rated power for extremely clean, uncolored sound. The PDX amp delivers crystal clear music every time, without unwanted background noise or static.

Power Supply: The PDX amplifier's power supply delivers tremendous headroom with low distortion and noise. The PDX amplifier has an extremely high total system efficiency of ~80% (power supply is rated at >90%, output stage is rated >90%).

Trim Rings: The PDX-series amps each have removable trim rings that can be custom painted to match your vehicle, or personalized to anything you want.

Stackable: The PDX-series amplifiers are 20% thinner than previous models at only 2" thick. A newly designed stacking system packs the amps closer together so there are no gaps and to save space in the trunk while directly coupling the amps heatsinks to help share cooling duties. The stacking plates are included with other PDX-series amplifiers.

Note: When stacking multiple amplifiers, do not install vertically or at an incline. Any stack installation other than parallel to the vehicle floor, invalidates the warranty.

LED: The top-mounted LED Power indicator glows blue when the amplifier is turned on.

Controls

Hidden Controls: The Alpine PDX amplifier's controls are hidden behind a decorative front panel. The front panel is removed by unscrewing one machine screw with the supplied Allen wrench and then prying the front panel open.

Gain Control: The PDX-V9 provides independent rotary controls for the front, rear, and sub channels to set the amplifier's gain according to the level of the incoming signal. The gain settings is continuously variable from 0.2V to 4.0V for the front and rear and 0.1V to 4.0V for the sub.

Optional Remote Bass Control: The amplifier has an RJ-25 modular jack for adding the optional RUX-KNOB Remote Bass Control for full control of the bass adjustments from the dash. You can also control multiple amps from the same controller with simple telephone cord adapters.

Note: The Remote Bass Control will only control the mono subwoofer channel (channel 5).

Crossovers: The Alpine PDX-V9 offers independent crossovers for the front, rear, and sub channels, which can be set as follows:

  • Front (High-pass only): 3-way switch (Off, x1, x10); Frequency: 30-600Hz (x1) or 300-6000Hz (x10)
  • Rear: 3-way switch (Off, HP, LP); Frequency: 30-600Hz (HP) or 300-6kHz (LP, if front switch set to x10); CH3/4 Input Switch (1/2 or 3/4)
  • Sub: Frequency: 50-600Hz (LP), 3-30Hz (Subsonic); SubW Input Switch (1+2+3+4 or SubW)

Connections

Terminal Layout: For wiring convenience, all of the inputs and outputs on the amplifier are on one side.

Quick Connect Plugs: The PDX series amplifier uses quick connect plugs to attach your system's speaker wires and power cables to the amp for a simple, error-free installation.

Quick Connect Speaker Terminals: The Alpine PDX-V9 includes 5 quick connect high-power speaker terminals. Bare speaker wire, up to 8 gauge, is held in place by screw clamps on the quick connectors. The speaker terminal quick connectors then plug into the amplifier.

Quick Connect Battery Terminals: The removable battery terminal quick connector features a low-loss, high-current design. It accepts up to 4GA wire for power and ground, to ensure your amp gets the power it needs while allowing for easy installation. The remote-turn on lead will accept up 12 gauge wire. The power, ground, and remote-turn on lead are secured by set-screws on quick connector. The battery terminal quick connector then plugs into the amplifier.

Line Level Input: The Alpine PDX-V9 is equipped with six gold-plated female RCA jacks.

Fuses: The Alpine PDX-V9 is equipped with two 40-amp ATC fuses.
