Our take on the Alpine PDR-V75

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.

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.2 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.

Great purchase

Richard from Houston, TX on 2/23/2019

Crutchfield Customer Review (What's this?)

Excellent for a mid-price system. Small footprint (single unit for 5 channels), plenty of power, great sound ... and ... Crutchfield! I'm powering Infinity Kappa's and an Infinity 12" underseat sub with plenty of head room. Self-installed with completely isolated circuit using 1 AWG power and ground direct to an Optima Yellowtop battery, and added a T-Spec 3 Farad Cap. Absolute quiet even at low volume, but great for blasting a little Queen of the Night Aria at the hip hop intruders, when called for. Very pleased.

Pros: See first line of review

Cons: I've none here

Alpine PDR review

Noel from Hackensack, NJ on 10/27/2018

Crutchfield Customer Review (What's this?)

Hi all, Normally do not post reviews but wish to let others know about this amplifier with regard to my experience. Amp had a noise hiss sound that would not go away using the high level input. Regardless of gain and even when reduced i would lose volume and distortion also would occur at a very low gain. quality of sound was great but not perfect and noticed that phone calls were not good as well with crackling noise at times. From the very start of install and i had done all possible trouble shoot and it was recommended to me to swap the amplifier at the very end after endless RCA uogrades and ground loop isolators. I would suggest to look into a better amp at all cost as this one does not have signal noise ratio to be good at all. Unfortunately, I had to return the Amp and it ended up costing me $50 dollars with Crutchfield, due to box being missing as i was not contemplating returning my purchase. Wish it could have been different considering all purchases and new amp upgrade i did. All other purchases went well so happy about that.

Pros: Small and compact and moderate power

Cons: Heats up to much at low volume and hiss noise level. No room to increase gain without the noise

Pros: Sounds amazing.

Cons: None so far

Great amp

Scott from Mandeville, LA on 9/8/2017

Great amp. I have it in my 2007 Nissan Xterra. I replaced the entire sound system at the same time. I have the amp powering Infinity Kappa 6.5 components in the front and rear doors and a JL Stealthbox which runs a 12" JL W3 sub. This amp provides more power than I need for the setup and the Dyno sheet it came with shows it making 100x4 @ 2ohms and 425x1 at 2ohms for the sub. Nice and compact amp and never gets hot. I would definitely buy again or reccomend.

Pros: power, compact size

Cons: Price might be the only con but it really isn't that bad and you get what you pay for.

Awesome amp

Kevin from Channelview, TX on 4/8/2017

This amp is awesome. I have it powering 2 JL C2 components in the front doors, 2 JL C2 coaxials in the back doors, and two JL 12w1 subs. It is loud, clean, and distortion free, and like others are saying, it puts out more power than it's rated at, and it doesn't even get hot in my trunk.

Pros: More than enough power for four speakers and one or two subs and distortion free

Cons: None really. It's not too expensive for what you get and this amp is wonderful. It does what I did in the 90s and early 2000s with two big amps.


Bryan from Hanford, CA on 1/29/2017

Clean sound from the leader in car audio. Once again proving that alpine is at the top of the game. Perfect

Pros: As always clean sound, top quality construction and out put levels above rated rms power.

Cons: A relatively large unit thats putting out less watts per cubic inch than

Much better than expected!

Eddie from Sandown, NH on 10/29/2016

I was looking for a decent class D amp for my civic as my current, older class AB amp was drawing too much at idle when the bass notes hit. My lights dimmed badly. I even tried a capacitor which helped but didn't eliminate the issue. I was skeptical at first because I've never owned a class D amp before and this meant that I had to rewire my car from 8 to 4 Guage wiring. After hours of working on the car, I tuned this new gem. Wow! This amp sounds fantastic. I have it powering Alpine type R components up front with matching coaxials in the rear and a JL Audio 10 inch w3v3 sub. I've read that some of the 5 channel sub sections of the amps have been weak. Not this one. Once I set the bass boost and subsonic filter, my sub hits just as hard as when I had a dedicated sub amp. Birth certificate shows 120x4 plus 423w to the sub in 2 ohms. It's plenty powerful and extremely clean. Best purchase I've made in a long time. The best part is; along with great sound, it cured my problem. No more dimming lights! Sweet

Pros: Clean, powerful, and a great value

Cons: None

Paul K from San Ramon, CA on 10/5/2016

Crutchfield Customer Review (What's this?)

Great performing 5-channel amp in a very small package. Plenty of RMS power to drive the 4 door speakers and a 10" sub. Installation is made much easier do to the compact size.

Pros: Clean Power, Small physical size, plenty of adjustability, reasonable price point.

Cons: None.

Class D is for me!

Rick from Brighton, MI on 7/18/2016

Crutchfield Customer Review (What's this?)

Great clear crisp sound in a small package. The "Verification Certificate" that comes from testing the actual amp had the power output rating as 25% higher than is advertised for the amp. I'm powering 4 Alpine SPR-68s and one 10" kicker sub and it's a great match.

Pros: Clear sound - don't need a more powerful amp - actual output is higher than advertised.

Cons: None

Great little amp

Scott S from Eugene, OR on 4/26/2016

Crutchfield Customer Review (What's this?)

Great little amp. Small size for the power, allowed for much more flexibility in install. Wiring going to one side makes it easier to install. Top side adjustments are also a plus. Currently have powering Morel Maximo 6.5 inch components in front and coax in rear and a 10" 250 watt infiniti subwoofer from a Kenwood KDC-X599. Overall happy with the sound.



Awesome Class D(elicious)

dpa from Milan Italy on 3/27/2016

Installed in a small citycar Daihatsu Charade. Certificate says 121x4 plus 411 @2ohm so maybe around 85x4 plus 300 @4 ohm. Matched with all-Hertz speakers, 2 way front kit ecx 165 WF 160 + tw 26 Energy, rear coaxial hcx 130 hi energy, bandpass sub 200. Powerful and clean, small size. Can't ask for more. Five star.

Pros: Sound and small size, easy connect and setup, variable subsonic filter, 2ch input possibility. High efficiency class D low battery drain. Cover protects setup switches and knobs from dust.

Cons: Being fitted under front seat is difficult to remove cover for further adjustments (my problem, however, not pdr-v75 problem)

Amazng Amp Alpine PDR-V75!!!

Kevin from Pennsylvania on 7/7/2015

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

This is a great amp both clean and powerful enough for my needs. It sits beneath my driver's seat (2003 Ford F-150 ext cab) with room to spare. This defintely wears the Alpine name. Well done Alpine well done!

Pros: Easy setup ,clean and powerful.

Cons: None yet

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

AudioPhilo from Oregon on 3/15/2015

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!!

Brian from Calimesa, CA on 2/25/2015

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

Alex from Florida on 1/13/2015

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

Jimmy from Jacksonville, NC on 9/11/2014

What a great amp and the size is great fit right under the passenger seat. Setup was easy and the sound is great.

Pros: Great sound, small footprint

Cons: none at this time.

Alpine Amplifier Rocks!

Lancew from Bothell, WA on 9/3/2014

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

AJT from Sarasota, FL on 8/23/2014

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.

Hands-on research

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). 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).

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.

Crutchfield asked  
Why did you buy this?

Harley's recommendation after another was backordered [ James  Mar 03, 2019 ]
Marisa my sales advisor helped me build a custom system for my specific needs. She recommended this amp for my application as I already had some new speakers that I am planning to use for my stereo install in my 1948 Dodge project. These people really listen to what you want and need for your install and they don't just try and push any old products out the door. Great experience calling Crutchfield. [ Gary  Feb 02, 2019 ]
My 15 year old Alpine MRV-450F amp fried itself last week so I decided to replace with a bigger (actually smaller), badder unit. I'm impressed with the smaller form factor and 30% additional power output. I have mine mounted inside the rear quarter panel wall and this model maintains the same cable runs and presents the adjustment knobs where I can see and access them by pulling the wall panel. The higher end amps from Alpine moved the control knobs to the side which puts them out of sight. [ Dave  Oct 17, 2018 ]
really good reviews and clean signal and quality is guaranteed due to the name [ Noel  Oct 04, 2018 ]
Brand Loyalty [ Clifton  May 11, 2018 ]
Good value point for the price, great reputation. [ Alan  Dec 06, 2017 ]
This Alpine Amp was recommended by Allen to match the Morel Speakers I purchased. [ Alton  Nov 03, 2017 ]
Awesome specs for the price. Matches the upgrades I am installing nearly perfectly. [ Big Poppa  Aug 26, 2017 ]
Small size, best output. Based on reviews, the amplifier is underrated. I'm looking forward to seeing the spec sheet. From what I've read, the amplifier puts out approx. 25% more power than advertised. Perfect for my JL C2-650X speakers and JL T10W3-D4. [ CodyY  Jul 25, 2017 ]
Alpine quality brand name, specs, Crutchfield support. [ A  Aug 07, 2016 ]
This amp is a serious upgrade to my toy haulers stereo system [ CHRISTOPHER S  Jul 11, 2016 ]
A better size and fit for the vehicle being used [ MARCUS K  May 25, 2016 ]

12 questions already asked

Sure, I'm using Pyle 2 ways and a separate sub they sound great. [ Kevin  Dec 30, 2018 ]
Yes, I am running two 2 ohm 12 in type r Subwoofers and a whole alpine system and the sound is awesome to this day it still impresses me on how hard it hits and the quality of the sound. [ Tanner  Dec 30, 2018 ]
Yes you need the 5 channel rca jacks adapter kit with this, so you can separate each speaker from rf and lf in the front and rr and lr in the back. subs have their own plugs for each sub r and l [ Dwain  Nov 22, 2018 ]
Yes you will. [ STEVEN J  Nov 22, 2018 ]
The minimum amount of rca patch cords needed is 4. The amp has a switch you can place in the "1 +2+3+4" position, all the signals are mixed and come out from the SUB W. This setting provides signal to the subwoofer channel when only 4 channel input is available. Otherwise, 5 channel rca patch cords will also work. [ Matthew  Nov 22, 2018 ]
Yes. [ j photo  Nov 22, 2018 ]
You are correct that wiring two 4-ohm speakers together in parallel will present a 2-ohm load. However, in order to get more personalized advice on an amplifier to work with your system, I would suggest contacting an Advisor directly by phone (888.955.6000) or online chat. They can go over the specs with you in more detail to ensure this amp is the right choice--or if not, they can suggest another one better suited for the job. Thanks! [ Larry  Jul 31, 2018 ]  Staff
Yes, you can leave it without anything plugged in. It will not damage the amp. [ Braedon  Mar 14, 2018 ]
Absolutely! The channel circuits are isolated. You can add the additional speaker later. [ Chris  Mar 14, 2018 ]
The short answer is yes. Doing so will cause no harm. [ Gordon  Mar 14, 2018 ]
It's definitely possible, sure. The subs would have to be wired to present no less than a 2 Ohm final load on the 5th channel but would receive up to 175 watts RMS each (350 combined) at that impedance. I hope that helps. My Bio: [ Ryan  Oct 04, 2017 ]  Staff
I bought new 4 ohms speakers for my gt mustang and had them replaced,but I used the factory 8 in subs and mine works perfectly [ Dwain  Nov 22, 2018 ]
each channel is separate so as long as the amp is 2 ohm stable your fine...I cant remember the specs off the top of my head but I love mine, tons of pure clean power out of such a small unit. I have mb quarts gt components and a super compact JL 8" power box and I can crank it until it feels like my ears are going to bleed before it starts to distort [ jeremy  Aug 01, 2017 ]
Yes, I did that with mine [ Edward  Jul 06, 2015 ]
My amp is mounted under my driver's seat. Being that it is solid state electronics, I don't think mounting it upside down would make a difference in performance or operation. [ EUGENE  Jul 01, 2015 ]
I would think that this would be an option, there is nothing loose on the unit so nothing should be falling out of place. [ James  Jul 01, 2015 ]
Yes you can, that's exactly what we are doing. We are mounting it in between the two speakers in the trunk. [ Jeff  Jun 29, 2015 ]
Yes it can be mounted upside down [ JACOB K  Jun 29, 2015 ]
AS long as it is well ventilated, I don't see why not. Keep in mind it's a class d amp and as such gives off very little heat. [ ALEXANDER  Jun 28, 2015 ]
4AWG Should be fine [ IVAN  Jun 03, 2015 ]
I would recommend 8 gauge. [ JACOB K  May 24, 2015 ]
4g is more than sufficient [ Trevor  May 24, 2015 ]
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy  Mar 10, 2015 ]  Staff
Thank you very much Richard!!! [ Vicko Zlosilo  Dec 23, 2014 ]
Yes, I am fairly certain, as I am driving four coax/component speakers at 4 ohms and a JL Audio 12" sub at 2 ohms. Very similar systems, so no problems. [ RICHARD W  Dec 23, 2014 ]
