Concentrated power for a full system

Alpine managed to pack more power per square inch into their PDR-V75 5-channel Power Density Reference amplifier than almost any other amp in its class. The PDR-V75 can put out 75 watts RMS per channel to your four full-range speakers, plus up to 350 watts RMS to a subwoofer, and it'll fit into many of the tight spaces you find in many cars and trucks these days. You can also use this versatile amp in 3-channel mode, driving a pair of high-performance speakers with 200 watts each, while still sending 350 watts RMS to a sub.

Tone control

Alpine included the tone controls you'll need to tune your system so your speakers and sub sound their best. You can use the high-pass filters to remove the extreme low bass from your full-range speakers, so they'll play more efficiently. You can adjust the subwoofer channel's low-pass filter, subsonic filter, and bass boost to get just the right bass tone, and you can add the optional RUX-KNOB remote bass knob to control your bass from the dash.

Superior sound and build quality

Alpine PDR-V75

Alpine built the PDR-V75 to exacting physical and electronic standards, resulting in a tough, powerful amp with an incredibly clean and noise-free output. All the electrical connections are located on one side, for more convenient and neat installations. Speaker-level inputs allow you to use this amp in almost any system, even one with a factory radio. And you can rotate the badge, so the Alpine logo can always display right side up, no matter which way you mount your PDR-V75.

Note: Sorry, Crutchfield cannot ship Alpine products to Guam or Puerto Rico.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Amazng Amp Alpine PDR-V75!!!

Written By Kevin, Pennsylvania on Tuesday, July 07, 2015

Crutchfield Customer Review (What's this?)

I purchased this amp after I had previously replaced my OEM door speakers and dash tweeters with kickers. When I installed those speakers you could tell everything was distorting and that the factory radio in my 2013 Dodge Dart Limited was not pushing anything close to what they needed. The speakers were probably getting about 25watts max fed to them rms. After driving around with them for about 6 months I finally got the funds and the effort to purchase this amplifier. I had an audio company install it becasue I have the 8.4" touch screen int he Dart and it is a very complicated install with the radio behind the glove compartment. After the audio place installed it the sound was crystal clear and you could tell it was much needed with the speakers. Now being fed around 90watts rms which is what the amp is actually rated at when you open up and see the rating slip in the box.

Pros: Small in size. - More power than rated at, about 15rms more. - Does not overheat like some other amps.

Cons: Only con is getting to the gain/crossover and other controls can be annoying to have to take the back plate off everytime. I left it off for about two weeks until i felt I was done tuning it and was good after that.

This amp is the truth

Crutchfield Customer Review (What's this?)

Great amp, this is my second one. This one takes care of all your speakers. Two amps are not needed. Power rating in the advertisement is lower than actual output. Power certificate that is enclosed rated the power output at about 25% higher than advertised. It has beautiful sound with my Kenwood receiver, four Kicker 6x8 speakers, and two 10" Alpine subs in a non ported box. This is my second one the other I have installed in my 2001 Honda van with a very similar set up. It sounds just as awesome as the set up in my Mustang. I highly recommend this amp it is small in size, and easy to install, and has very powerful output!

Pros: I highly recommend this amp it is small in size, and easy to install, and has very powerful output!

Cons: NONE

Awesome Amplifier

Written By AudioPhilo, Oregon on Sunday, March 15, 2015

Recently installed a pair of Fosgate T-1682's up front and a pair of Alpine SPR-68's in the rear of my 04 Explorer (Eddie Bauer).

The head unit is an Alpine CDA-117, and it will run these 4 mids OK at 18w RMS, however with an Alpine SWR-12D4 running off a 500w mono-block in the rear it became obvious real quick that these were going to need more juice to keep up. So I picked up an Alpine PDR-V75 amplifier (had to do it that day so could not order from Crutchfield, and the local shop didn't carry the 4 channel PDR-F50). A few hours later I had it all installed and, wow the system came ALIVE! Took ~20 minutes to get everything dialed in just right, but once done it sounds amazing.

My system used to have a dead spot between about 90-180Hz, not anymore. This amp puts out clean, LOUD audio. With the mid amp gain set at half way it gets uncomfortably loud way before it distorts. Have tested with Bass305, Rammstein, Enya, new popular music everything sounds awesome!

It puts out super clean mids and highs. If you need more power than this you may already be deaf.

Pros: Clean, powerful mids and highs. Birth certificate showing a rating of about 20% above specification!

Cons: A little bit too much amplification in the voice and guitar range. Be sure you can tune your system upstream from this amp.

I love this AMP!!

I have this Alpine PDR-V75 5 channel amp hooked up to my Tahoe factory head unit and speakers up front I'm using Alpines new S 6 1/2 plus components the sub I'm using is a JL audio W3v3 2 ohm in ported box. All I could say is WOW blown away every time I get in and drive. The amp powers averything perfectly!

Pros: Small, looks nice especially when the blue light is lit, powerfull!!

Cons: Haven't found 1 yet

compact and powerful

Written By Alex, Florida on Tuesday, January 13, 2015

Crutchfield Customer Review (What's this?)

Class D amps have come a long way: They deliver increased power, require less space (due to lack of heat shields), and generate less heat. This amp is perfect for small cars, motorcycles, boats, etc.

Pros: Fit under the passenger seat of my Mini Cooper (so that should demonstrate how small it actually is). Nice to have one amp that drives front and back speakers as well as a subwoofer. It's a D class amp, so it gives off much less heat (important in hot climates like Florida). The sound is clean and crisp. I just cannot believe it's not a class A amp.

Cons: This amp has truly met all my needs. Unless you're into huge power, speakers, etc, why would you need more?

Great Amp

Crutchfield Customer Review (What's this?)

I had this amplifier installed in my new Kia Forte this past weekend. I wanted to keep the factory unit, but change out the speakers and add a sub. I am blown away every time I get into my car! This amp makes all the channels sound very clean, crisp, and powerful! You can't go wrong with this amp. I am very happy with it.

Pros: Clean, crisp, & powerful sound. Many superb features. Small and lightweight.

Cons: None.

Compact Power

Written By AJT, Sarasota, FL on Saturday, August 23, 2014

Alpine Verification Certificate rated the actual power output: 120x4 + 420x1 @ 2ohms 90x4 +350x1 @ 4ohms.

Very clean minimalistic design. Fits easily under the passenger seat of my Subaru WRX. Tremendous amount of power in a small package. I have this amplifier Bi-amping a set of Focal PS165V Components. Bass is very tight, and the highs are crystal clear. Exhibits outstanding definition and stereo separation. I cannot detect any audible distortion before the volume starts to hurt my ears ( :

I would not hesitate to recommend this amplifier to any car audio enthusiast.

Product Research



Channel Design: The Alpine PDR-V75 can be configured as a 5-channel amplifier for powering two pairs of speakers and a subwoofer. It can also be configured as a 4-channel or 3-channel amplifier. The amplifier is stable to 2-ohms in stereo, 4-ohms when bridged.

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples). Using CEA-2006 criteria, the Alpine PDR-V75 is rated at 75 watts RMS x 4 channels and 250 watts RMS x 1 channel with an 87 dBA signal to noise ratio. The signal to noise ratio at the rated power output (not CEA-2006 conditions) is 105 dB for the full range channels and 110 dB for the subwoofer channel.

LED: The top mounted LED Power indicator glows blue when the amplifier is turned on and changes to red when the protection circuit is engaged.

Speaker Level Inputs: The RCA inputs will accept either speaker-level or line level signals from your car's head unit. A speaker level signal is connected to the RCA inputs using a speaker wire to RCA adapter (sold separately).

Auto Turn-on: When using a speaker level input, the amp will turn on automatically when it senses the input signal.

Verification Certificate: The amplifier comes with a certificate that lists the RMS power output of the specific amplifier. It also lists the model number, serial number, test date, and the test conditions (14.4 volts, 2 ohms).


Hidden Controls: The amplifier's controls are hidden under a cover plate. The plate is removed by unscrewing two machine screws with the supplied 2mm Allen wrench.

Independent Controls: There are independent controls and crossovers for Channels 1&2, Channels 3&4, and the Subwoofer channel:

  • Gain Controls: The rotary gain controls, for matching the amp's input sensitivity to the connected head unit, are continuously variable from 0.2 to 4.0 volts for the full range channels, and 0.1 to 4.0 volts for the Subwoofer channel. You'll need a small screwdriver (not included) for setting the gain.
  • Crossover: The full range channels (1&2 and 3&4) each have a -12 db/octave high-pass filter that can be turned on or off. The cutoff frequency can be set between 50Hz and 400Hz. The Subwoofer channel has a -24 dB/octave low-pass filter that cannot be turned off. The cutoff frequency can be set between 50Hz and 400Hz. The Sub channel's -24 dB/octave Subsonic filter can be set between 8Hz and 40Hz. It cuts ultra-low frequencies from the input signal before being amplified to protect the speakers and to minimize wasted power.
  • Input Channel: The two-position input switches configure the inputs. For the full-range channels, you can set the inputs to "1/2" (signal from inputs 1 and 2 are sent to channels 3 and 4--no Y-adapter necessary) or "3/4" (Channels 1&2 and 3&4 are independent--a 4-channel source is required). For the Subwoofer channel, you can set the inputs to "1+2+3+4" (signals from the full-range channels are mixed and sent to the SubW channel) or "SubW" (Left/Right signals from the SubW input are present).
  • Bass EQ: The Bass EQ circuit provides a variable 0 dB to +12 dB signal boost, centered at 50 Hz to the Subwoofer channel.

Remote Bass Control: Alpine's RUX-KNOB wired remote control (sold separately) plugs into the RJ-25 Remote Bass Control terminal, giving you attenuation control of the sub(s) from anywhere in the car (0 to -20 dB).


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

Power Input: Two set-screw terminals are provided for connecting the power and ground cables. The terminals accept up to 4-gauge wire (a 4-gauge wiring kit is recommended). The set screws are tightened/loosened with the included 3mm Allen wrench.

Remote Turn-on: The remote turn-on set screw terminal will accept up to 12-gauge wire. The set screw is tightened/loosened with the included 2mm Allen wrench.

Speaker Outputs: The five pairs of speaker outputs set-screw terminals will accept up to 12-gauge wire. The set screws are tightened/loosened with the included 2mm Allen wrench.

Signal Input: The Alpine PDR-V75 is equipped with three pairs of female RCA jack inputs: Channel 1(L)/2(R), Channel 3(L)/4(R), and SubW(L)/SubW(R).

Remote Bass Control: An RJ-25 jack is provided for the optional RUX-KNOB wired remote control.

Fuses: The amp is protected with two 40-amp ATO fuses.
