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.

Product Research



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.


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)


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.

[ Cosmo  Jun 13, 2019 ]  Staff
I have purchased the pdx-v9 and it has four mounting screws. I was going to mount this to a metal bracket under the passenger seat. The bracket itself is directly mounted to the seat bracket which is grounded. My question is whether I should attempt to isolate the amp on some medium such that it's chasis is not connected to ground? I've read that double grounding can have adverse effects.
[ Lane  Feb 24, 2018 ]
4 answers
Grounded is grounded. Amp to wire to chassis or amp to chassis, same thing. You should run your negative wire from the terminal to the chassis but grounding the amp also is fine.
[ Ronald  Mar 14, 2018 ]
Yes, probably a good idea. I had the luxury of mounting my PDX-V9 on a 3/4 inch platform of 7 ply birch plywood, very nice to screw the PDX-V9 into. And I ran dedicated grounds to each amp (I have two) from a GND junction box to avoid any ground loops, which are just grounds that differ very slightly in their "resistance" to a perfect ground thus set up a small noise current. (I'm an EE by degree.)
[ John Kuthe  Mar 14, 2018 ]
My amp is isolated all on its own-works and sounds great. If I were you, isolate the amp.
[ The Chimney  Mar 14, 2018 ]
In my opinion I have always mounted amps isolated from any other ground source. Sometimes it will create a ground loop which occassionally creates a patch for engine noise. Not in every case but its possible so if you can isolate the amp chassis I would recommend it. Hope this helps
[ Stephen  Mar 14, 2018 ]
would this have enough power for a 2ohm 600 watt rms sub, specifically the Punch P3D4-12, since it's max'd out at 500 watt rms?
[ chefbv  Nov 22, 2017 ]
1 answer
The 5th channel of the Alpine PDX-V9 provides up to 500 watts RMS so, it will not realize the full potential of the RF P3D4-12 (600 RMS) but it will still power it very well.
[ Ryan  Nov 29, 2017 ]  Staff
How do you bridge this amp if you are planning on using it for two full range speakers and one sub?

Can i run the front and rears at 4ohms and the sub at 2ohms? and how bad of and idea is it to run a 600rms sub (Rockford Fosgate T110D4) with this amp since it is a 500rms sub channel (never really going to push the system) space is a real concern.
[ brian  Aug 25, 2017 ]

That's pretty much the exact same way I'm running my system with competition speakers in the doors and the JL sub. In doing so I found that I had to dial down the amp for cooling and the competition alpine r types couldn't handle that much power anyway. I was looking for studio quality sound and nailed it.
[ RAYMOND L  Aug 26, 2017 ]
yes you can run doors at 4 ohms and sub at 2 ohms sub should run just fine as well
[ austin building  Aug 26, 2017 ]
Can I use the sub output to run an 8 ohm sub? If so, what will the power be?
[ Luke  Apr 13, 2017 ]
1 answer
The higher resistance of the 8 Ohm sub will get about half the rated 4 Ohm wattage so; around 250 RMS. I hope that helps! My Bio:

Will this amp work to push a 12" w7? It's a 3ohm sub.
[ Brice  Mar 02, 2017 ]
1 answer
No, you need like 1000 watt amp. I love the 5 ch pdx, but it is only like 250 watts, not goona do much for a w7
[ austin building  Mar 02, 2017 ]
Hi...will this amp be able to run an Alpine SWR-10D4 sub on the 500W RMS channel only efficiently? I have been told that i wont get the best quality out of the Sub as its rated at 1000W RMS.....please help!!!!
[ hugo  Jan 13, 2017 ]

I forgot to tell you I am powering the same sub with a sundownaudio 1500RMS at 1 ohm, currently on a two ohm load feeding 800 watts to the sub. Perfect match
[ Daril  Jan 15, 2017 ]
Normally you want to stay over 75% of your subwoofer RMS. This sub is rated at 750watts RMS not 1000, misleading information from alpine. RMS is 4 times less the max power in this case 3000. With this amp rated at 500 you are only providing 67% of your sub rated RMS (750) and while it would thump I would get a bigger amp. The reason for this is because when you underpower a sub, trying to get louder you will send clipped signal. It is always better to get an amp either rated the same as the sub or more, that way you will have more room left letting your amp work cooler and insuring your signal is clear.
[ Daril  Jan 15, 2017 ]
Yes it'll run fine and sound good, but will get a good amount louder and sound great if you put 1000 rms to it.
[ JAROD  Jan 13, 2017 ]
Can you run 100Wx4 @4-ohm AND 500W @2-ohm?.... my sub is 4-ohm dvc and my door speakers are 4 ohm.
[ Dylan S  Dec 25, 2016 ]

Yes you can run the sub at 2 ohm and the door speakers at 4 ohm, that is exactly what I did, i ran 4 alpine type r 61/2" @ 4ohm and a alpine type r 8" sub 2 ohm.

Looking for some advice on how to set the switches on the back, I am tapping off 1 channel from my stock HU, im running a set components in my front door, coaxials in the rear and a slim line sub, anyone know the best settings for the switches, HP BP OFF, ×1, ×10? Im new to this and can't get my head round it.
[ Dan  Sep 26, 2016 ]
1 answer
This setting means the High Pass filter frequency cut off, so if really depends on what channels you are running on this output and what speakers. If the speakers have their own crossovers simply leave it off or set it to a high value to protect the speakers from blowing at high volume.
[ Dominic  Sep 27, 2016 ]
Will this run 2 alpine shallows at 300-600 rms 4 ohms?
[ Coble  Aug 09, 2016 ]
1 answer
This amp would not run 2 shallow subwoofers that have the RMS watt range you listed. Each subwoofer would get 250 watts and that's lower than the 300 minimum that you indicated your subwoofers need. But we have amps that can and shallow subwoofers that will run on this amp. Feel free to call an advisor on 1-800-324-9695 for a personal recommendation! My Bio:
[ Paul  Aug 12, 2016 ]  Staff
Will the PDX-V9 move a Rockford Fosgate P2-2X12 on the sub channel as it comes pre wired at 1 ohm load, or will it need the get rewired at 4 ohms using serial on the double voice coils of each speaker and parallel on the two speakers for a final 4 ohm load Also will it be powerful enough to move those two p2's at 4 ohms?

It can move rms 500 watts on 4 and 2 ohm on the sub channel...I have an alpine type-r 15" hooked up and it hits really nice
[ Homer  Mar 14, 2016 ]
Looking to set this up with a stock HU, LC2I, Polk Audio db6501, and a JL 12W6V3. The manual doesn't describe the scenario where I only output to channel in an unbridged configuration - the Polks are only rated 100W RMS. I have two options the way I see it: 1. Run off channels 1 and 2 to the L/R for the Polks. (there is a crossover for the woofer/tweeter) 2. Run from all four channels, two for woofers, two for tweeters and use the amp as a crossover. Which option is the best for me? Why?
[ Aorel  Jan 11, 2016 ]

Enter an answerI would do the following assuming you have front and rear full range speaker locations in your car. - Will you want to use the fader in the factory head unit? If so, then run the Audiocontrol unit off the front OEM speaker channels to the PDX-V9, and run the rear speaker channels in stock connection configuration like nothing was added. - If you run it this way, then you would run two main RCA channels from the Audiocontrol to the PDX-V9, then using the selectable input switches on the PDX, run 4 + 1 channel out to the Polk mids, tweets, and JL subwoofer. All 4 channels will provide a dedicated 100W RMS to each midrange and each tweeter. - This would eliminate the need for the passive crossover that came with the Polks. That is normally fine as passive crossovers from the lower price point speaker sets are nothing special. The active crossover in the Alpine PDX-V9 will provide better sound quality and more precise tuning over crossover points and gain settings. The only disadvantage is you will not know the EXACT crossover points. For this, you will need an o-scope or RTA meter to measure where the roll off frequencies will be. For starters, shoot for somewhere in the 3-4K range for low pass midrange and high pass tweeters. I tried looking up the crossover values built into your Polks, but could only find the -12dB value and not the frequency. - For the subwoofer channel, you have two choices: 1) Run the RCA "bass" channels from the Audiocontrol to the subwoofer channel input on the Alpine. This way, you can play with the "Accubass" to see if it is worth the hype. 2) Ignore the RCA "bass" channels from the Audiocontrol and have the Alpine control all bass functions. If so, I HIGHLY recommend investing $30-$50 for the RUX-KNOB. It easily mounts anywhere and uses a phone cable to connect to an input port on the PDX-V9. When plugged in, it overrides the gain control for the sub channel and allows you to adjust subwoofer volume on the fly. to this question.
[ Craig  Jan 19, 2016 ]
I had mine professional installed, I'm not sure how they set it up. Sorry I couldn't be of more assistance.
[ jeff  Jan 12, 2016 ]
Well if externally from the amp there is a crossover from the woofer to tweeter I would run that off the amp...basically the amp has 5 channels a front left/right a rear left/right and a sub channel each output 100watts...if your only running the 2 speakers off the amp with the sub I would just bridge 1-4 to make only 2 channel output and hook the speakers up that way...the speakers will handle the power and you'll just have to make sure you don't over gain the long as you don't over gain you won't be over feeding the speakers...also depending on the size of your Polk speakers you may want to set the crossover for them off the amp because it will make the music clearer...I would not run a separate channel to the tweeters because the crossover doesn't cover the ranges you need to cut low levels out also you would need a way to feed signal the same as the other speaker so you would need an rca splitter...all that being should just bridge and run to the speakers with an in-line crossover between the woofer and tweeter and make sure you adjust your gain settings correctly
[ Homer  Jan 12, 2016 ]
I would use one channel per component speaker (woofer and tweeter) because the RMS rating is for the entire component speaker system not for each individual component (i.e tweeter + woofer + crossover = RMS).

I had it professionally installed, I didn't hook it up.
[ jeff  Feb 03, 2015 ]
Dosen't matter, the amp internally adjusts the polarity to be correct. The only thing I did to be consistent was to put all the plugs the same way. Don't think it mattered, was more of an ocd thing.
[ Brian  Feb 02, 2015 ]
They go either way didn't matter this is a killer little amp it learns to power what way you plug them in really. Neat amp it will get louder as you go
[ johnathan  Jan 31, 2015 ]
Either way, the negative makes its connection on the outside of the plug.
[ Christopher  Jan 31, 2015 ]
It does not matter which way you put the plugs in i put all mine + up...i dont even think it matters if they all go the same direction but to be safe i would put all in the same direction
[ Homer  Jan 31, 2015 ]
It doesn't matter as long as you match your positive wire to the + and the negative wire to the - . The outside of the plug supplies one of the signals while the inside of the plug supplies the other. Similar to how RCA cables work. If your truly interested in which signal goes where, use a continuity tester.
[ TODD  Jan 31, 2015 ]
It doesn't matter. The Amp will auto-sense the polarity once the connector is attached to the Amp. Just connect everything with everything off.
[ CHRISTOPHER  Jan 31, 2015 ]
That's the nice thing about these amps. They can be plugged in either way without any problems.. I don't remember which way I did mine, but they're all facing the same way just to look nice.

Anyone using this amp's sub channel with a JL 13TW5V2-4 (250-600 watts RMS)? I'm an old school PPI guy, and I've never owned an Alpine amp (yet).
