Customer Ratings & Reviews

Great value for money.

Pros: Great looking amplifier, and it has very clean sound with good specifications. Nice and compact, and fits under front seats very easily. Great value for money.

Cons: It doesn't have bass boost feature.

Great all in one amp

This amp is fantastic, power is true as advertised and the sub section is stable to 1 ohm. It's really tiny and fits perfectly under the seat of my 2013 Mazda CX-5. I have it running off an audiocontrol LC6i and powering my OEM speakers for now and a single 12" MB Quart PS3 sub at 4 ohms. I get a clean, noise free signal from my factory head unit. Everything on the amp seems solid, and it's marine certified so you can use it in a jeep or a boat as well. It is capable of running all 5 channels off a single pair of RCA's if needed which makes installation very flexible. The included bass boost knob is great and there is a green light on it that is on when the amp is on. Overall I'm very happy with my purchase and would definitely buy this amp again.

Good Value 5 - Channel Amplifier

Pros:
- High Efficiency: doesn't draw a lot of current, runs cool
- Compact design: makes installation easy
- Sub section very powerful: drives two JL 10s easily
- Versatile inputs: one set of preamp inputs can drive all 5 channels
- Superb Sound Quality

Cons:
- Subsonic Filter Non-defeat able
- Gain Control a little too sensitive
- Not Gold Plated Input/Output Terminals
- Crossover Controls dont have frequency markings
- No High Level Inputs (not a con for me but some might need it for OEM integration)

Great sound

I just recently brought this Polk Audio amp. It is fantastic. I installed it in my boat and it performs beyond expectations. Wish I would have bought one years ago. Easy to install and takes up very little space.

Small Amp with lots of power!

I got this as a gift to replace another 5ch amp not worth mentioning (CEA rated amps are really worth getting). Enough power to run 2 sets of Polk db6501 components and 2 10" Polk MM subs in a 1.2ci sealed box. Just make sure to tune your amp and you'll get loud clean distortion free music out of this little thing. I would highly recommend this if you're in the market for a 5ch amp.

great amp

works great and paired with polk speakers it makes them pound hard the only thing the sub control dont seam like it really changes it much other than that it works great

Great amp, clean sound, compact

In Toyota king cab pickup, mated to NVX door and rear speakers and Kicker loaded 10" (dual 2 ohm driver) sub that fits nicely behind driver. Once frequency crossovers were properly tuned and levels adjusted--wow! Great sound--Rock, funk, jazz (horns, cymbals, real drums, etc). Tight punchy bass, nice ringing highs with low distortion. I rewired the sub from 4 to 1 ohm to take full advantage of the amp, and limited the voltage to ensure my kids don't blow the speaker!

Instruction manual is weak--needs better section on proper amp setup. When you plug in the Subwoofer level adjust, you need to turn it up to 50% or so to begin to hear anything. Or, first leave it unplugged from the amp, set your max levels, then plug it in. If the adjuster is left turned all the way down (as mine came) you'll get NO SOUND out of the subwoofer channel. Neither the Polk nor the SonicE tech's knew to do this during our "debug" sessions! Silly, in hindsight. 3 stars for durability only because I haven't had it long enough to know.

Excellent choise

Quality crystal clear sound
Great base sound but and even better sound from the
Super tweeters
I love it and if you buy it you will love it too.

Best 5 channel ever owned

Absolutely as powerful as it states. I am using Focal components with this unit and a Memphis M3 12 at 2ohms. I am also using a capacitor and have nondoubt that this single all in one amp is top notch quality fairly small packge. Only hassle was mounting it. Clumsy design for screws. I ended up using 2.5 inch wood screws tonreach through corner mounts. Very happy...i have had other 5 channels before and had many issues...first time I've been happy with an all in one unit!

Good value

First time trying Polk audio for my car/truck. Very happy so far. Small in size but sounds great and has plenty of power for my four component speakers and sub. Can't give 5 stars on durability yet but very pleased on everything else.

Dxi 651 speakers

Polk has never disappointed me. The quality of product is much better vs Kenw00d or P10neer. So is their quality control and testing. I like how it came with a foam type of spacer to go between the speaker and door panel- helps reduce vibration kind of like Dynamat would. Some of their speakers I had before had like a spray-on rubber? on back of the speaker frame. Clearer sound always with them.

Very good sound

Purchased these speakers to replace a set of worn our speakers in my 99 Tahoe. These were of considerably better quality than the originals and installed nicely in place of the originals. These speakers have a significantly improved base response over the stock speakers. and do not distort when driven by the stock amp in the Tahoe. This was a good solution for a replacement speaker that made a good sound system even better.

Decent

Sound good but aren't super loud, pretty good bass over factory, highs are clear. All in all there way better than stock and for the price there great I'd buy them again

Good sound at a good price

I installed these in the front of my 2004 Honda Civic LX sedan. They fit with no issue, using a 0.5" thick mounting bracket (the speakers come with their own, but I reused the bracket from the previous speakers I had installed).

The sound is good, especially for the cost. They do not provide deep, powerful bass, but would be a great improvement over most OEM speakers. I use these speakers alongside a subwoofer, so I want the subwoofer to handle the low frequency end anyway.

Great speaker good range

Installed speakers In kick panel and rear side panel on a 65 mustang they fit well and sound great bought 6 by 9 Polk speakers for back deck sound great will buy more from sonic when I need more stereo components

Polk good OEM Replacement

Nice sound for OEM Replacement speakers. You may need brackets for Subaru Crosstrek or use cheap OEM speaker housing and cut out old woofer to make adapter for this speaker.

great value

I have put this speaker in about cars now some just as stock upgrades and others powered by amp. sound is great either way. I have a set of them on a golfcart and they sound amazing. would buy again

Awesome Sound!!!

I love anything Polk Audio and these speakers will not disappoint you!

Miata spesker replacement

I got these speakers to replace the stock speakers in My 90 Miata. They were a direct replacement other than having to drill two new mounting holes. The speakers fit fine with room to spar and the stock grills covered them fine. The speakers are a great improvement over the stock speakers.

amazing sound

I replaced the stock speakers in my 2008 Toyota Avalon with these, install was a breeze and I'm glad I did it - they sound amazing

Polk DXi1240DVC

Polk 12" works great paired with Belva ported box and 1500 watt amp in my BMW, but sounds great and is all is expected.

budget hi-fi

Really for the money it's tough to beat for what you get. First off the frequency response with or without amplification is amazing with next to no audible distortion. Moreover the materials for speakers are inline with those costing twice as much. Generally, with few exceptions these will please most regardless of music taste without a sub.

High clarity

I replaced the factory seakers in my wife's 2013 hyundai elantra.Sounds 100% better.

DXi1240DVC

This polk came as a package with the BBX112 BK enclosure and did a really good job in my wife's BMW, I would recommend for a stater who wants a little extra bump for the daily commute.

OK

The highs and mids are good but the base is lacking. I had a set of Pioneers that were better. Was hoping for better but the price wasn't bad.

Good speakers

I bought these by looking at the specs I needed. 35 - 22000 Hz, Sensitivity: 92dB, They sound great and loud.

Sound great! Bit of a custom fit in 2006 Wrangler

I installed these into a 2006 Wrangler's rear sound pods. They aren't a drop in replacement though. Had to carefully align them as they barely fit onto the cutout in the pods, and had make modifications to allow the factory speed clips to be used. In order to install the grills I used a heat gun to heat up the plastic pod and mold the pods to the grills so they fit flush. Also stuffed the pods with polyfil batting to help smooth out the bass. Glued the foam deals that came with the speakers to them before mounting to help seal frame to the plastic sound pod. So far seems to have worked out well. I would recommend 5-1/4 thought which should be a drop in replacement.

Nice speakers for low money

The Polk DXI 651 speakers sound great for the low cost. We bought two sets to replace the factory RAV4 speakers and we are very happy with the result. Relatively simple install and great sound. I only wish the speakers came with the proper electrical connectors.

Best bang for the buck

I LOVE these speakers. I've always been a fan of Polk Audio for their sound quality, especially in relation to the pricepoint, but these speakers have really blown me away. For the price of a pair of low-end Pioneers, you get a MUCH higher quality speaker, with amazing sound quality, and best of all, they're marine certified, which means I don't have to worry if they accidentally get a little bit wet. They come with adapter plates, which are nice and sturdy, but you can still break off the tabs you don't need easily with pliers. They also come with speaker grilles, which I did not use. Mounting hardware is included, however wiring leads are NOT included, so make sure you order some speaker harness adapters.

I fully recommend these for anyone looking for a nice speaker on a budget.

Great sound!

These speakers sound awesome. Tight clean mid bass and mellow highs work well with all types of music. They have a premium build quality and sound at a great price.

Polk Audio DXi651

I installed these in the rear doors of my 98 Grand Cherokee and they sound great. Great midrange speakers if you have a subwoofer.

Polk Speskers

Great product from a OUTSTANDING merchant! Install in a 2011 Silverado 2500HD was smooth.

very nice sound

Polk audio, the name says everything. I will be purchasing the 6x9 next. Very good product for this price range.

Miata spesker replacement

I got these speakers to replace the stock speakers in My 90 Miata. They were a direct replacement other than having to drill two new mounting holes. The speakers fit fine with room to spar and the stock grills covered them fine. The speakers are a great improvement over the stock speakers.

Awesome Amp

clean power in a very small footprint, amp temperature is very cool compared to other amps that I have owned, no distortion at all

Inexpensive Quality

Installed these in the front doors of my Gen2 Tundra Crewmax because of the mounting depth and RMS rating and they fit perfect. The real bonus came when I heard the sound come out of these babies. Crisp, clear and powerful. Satisfied is an understatement. If you're looking to upgrade your factory sound these won't disappoint.

Great AMP, running in Boat

I purchased this amp to replace a old amp. WOW, the Class D technology is worth every penny. I am running four 7.5" wake tower, two 10" subs, two 5.25 wake tower, six tweeters. Disclaimer, all the speakers are high efficiency speakers meaning they don't take allot to be loud. No distortion, extremely loud. I cannot believe so much power from such a small amp.

PERFECT FIT...

I WAS PREVIOUSLY RUNNING A POWERBASS 1100.5, IN MY 1992 HONDA ACCORD EX... IT KEPT OVERHEATING, AND GOING INTO PROTECTION MODE... I NEEDED A CLASS D AMP TO PROVIDE RELIABLE SERVICE... I PURCHASED A POLK AUDIO PAD5000.5 FROM AMAZON... IT LASTED ABOUT 3 MONTHS, BEFORE THE LEFT REAR CHANNEL WENT OUT... I WAS STUCK WITH A BAD AMP, BECAUSE I DIDN'T PURCHASE IT FROM AN AUTHORIZED RETAILER... AFTER FINDING OUT THAT SONIC ELECTRONIX WAS AN AUTHORIZED POLK AUDIO RETAILER, I QUICKLY ORDERED A NEW AMP... NOW, I HAVE THE PERFECT AMP TO COMPLETE MY SETUP, WITH THE ASSURANCE OF WARRANTY COVERAGE... THE AMP ARRIVED IN ABOUT 2 DAYS, AND THE SHIPPING WAS FREE... THANKS AGAIN, SONIC ELECTRONIX!!!...

Excellent Speakers for the Price

These speakers sound many times better than the OEM ones in my 370z. The build quality is excellent, and they look great.

Overall, the install was very easy. Fitment was excellent thanks to the included universal bracket.

By Paul on September 28, 2017 Verified purchase

Holy cow!!

Bought this as a replacement for another brand and all I can say is wow!! Sharp crisp bass!! Definitely would buy again!!

Bass on 40 bucks

For price the polk is great must have sealed 1 cubic ft box. Not for small enclosure this bass on budget is great.only downside the speaker terminals are not push terminals but what u expect for 40 bucks.

By JORGE on November 7, 2016 Verified purchase

Works Just Fine

So far so good. I have it hooked to a Kenwood 600 watt amp and it sounds great.

For the money can't be beat.

Nice,crisp sound for those that want bass but no trunk rattle

By kinsley on October 9, 2016 Verified purchase

DXi is legit

to be honest I never had heard of DXi mostly I knew about the DB series but this 12" sub right here really provides a lot of boom, if anything I think they underrate their subs unlike some of the low end brands out there, I'd consider this a competitor to Rocford and Kicker at the fraction of the price. I put this in a sealed box, wired to a 2000 watt belva amp Sonic recommended and the boom I get is 10/10

By James Y. on June 30, 2016 Verified purchase

Quality Sound on a budget

Money is tight and I needed a budget subwoofer that could satisfy my needs. I did not know what to expect when I purchased this sub but was blown away when the first time I hooked it up. I am running it on a NVX MVPA1 and the bass thumps in my trunk. Need to purchase some sound dampener because of how hard this thing hits.

By Jesus on June 30, 2016 Verified purchase

Fantastic!!!

Having used a JBL 5 Channel amp for quite some time set the bar high, but the 5000.5 has met and exceeded expectation. Its compact and delivers more than adequate power to my sub and my mirus speakers. I am thrilled beyond words. Thanks Sonix Electronix!!
