Overview

Our take on the Polk Audio db651s

Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk Audio db651s

Give new life to your music

Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk's db651s shallow-mount speakers feature 6-1/2" woofers made from a polymer/mica composite and durable rubber surrounds that stand up to heat and moisture. Liquid-cooled 3/4" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction. With a 2" mounting depth, these speakers can fit into some tight places. The built-in two-way crossovers keep the high and low frequencies flowing to the proper drivers for seamless, efficient audio.

These speakers feature stainless steel mounting hardware and muscular ABS grilles that will add a stylish touch to your car's interior. And Polk certifies their db Series speakers for marine applications, so they're a great choice for your boat, motorcycle, or ATV.

2016 Jeep Wrangler Unlimited. I put these speakers in my roll bar. Very clear highs and mids. These speakers can't handle bass.

Features

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Woofer Cones: Each speaker features a Dynamic Balance polymer/mica composite mineral-filled cone. The cones are stiff and lightweight for big sound and low distortion.

Butyl Rubber Surrounds: For a smoother response and improved durability, the woofers use butyl rubber surrounds.

Kapton Voice Coil Former: The low-mass Kapton Voice Coil former is lightweight for high sound output. Kapton's high melting temperature (725°F) ensures high power handling and longer reliability.

Silk/Polymer Composite Tweeters: The 3/4" liquid-cooled, silk/polymer composite tweeters provide clear, detailed highs. The tweeters use neodymium magnets.

2-way Crossover Network: The built-in 2-way crossover network sends the appropriate frequencies to each driver for cleaner sound and better imaging.

Grilles: Strong ABS plastic grilles are included. These computer optimized grilles are based on exclusive MOMO designs.

Preston, I put these speakers in a 1996 Chrysler Sebring LXI coupe. They replaced the original speakers in the doors. The car has the stock Infinity stereo system in it which produces 15 W RMS per channel. It has plenty of volume in my car at 33% output. I would think they would work in your car at 14 W RMS per channel. They are a very nice sounding speaker with a heavy duty butyl rubber suspension which will not deteriorate like the original foam suspension ones that came with the car. [ David  Aug 15, 2016 ]
I would say yes; any aftermarket speaker will outperform old factory speakers. That said, aftermarket speakers are made to perform at higher rms wattage, so don't expect extreme results without an amp. I connected mine to an alpine head unit with 22 rms and the sound quality was a major improvement. I guess it depends on your level of expectations. Polk makes great sounding speakers. I would buy Polk again. [ Matthew  Aug 15, 2016 ]
Thanks for your question. For information on selecting the best amp for your speakers 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. [ Kenny  Apr 25, 2016 ]  Staff

They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  Mar 25, 2016 ]  Staff
Crutchfield. Can answer all your questions and get you what will fit and sound amazing. [ David  Jan 06, 2016 ]
2" Top Mount depth. That means that they will go 2" deeper than the flange that they are mounted to. Stick a ruler through the mounting hole and rotate around the outer edge and make sure that you have 2" all the way around. [ John  Nov 22, 2015 ]
I have a Honda S2K and not a MR2 but I had no difficulty with the installation. If you used Crutchfield's search for what fits you particular car year and model, you can't go wrong. These were a perfect fit for my car and sould great of course, they are Polks. [ SHAR  Jul 13, 2015 ]
The 3 screws will be fine, that is how I mounted them in my truck and my miata. These speakers are great, extremely crisp compared to stock. And I would suppose the speaker mounting holes at 120 degrees would make them 2 and 1/6th inches apart but I'm not sure how you would measure that if you were drilling holes. I would probably just use the speaker bracket as a template then stick a skinny marker or pencil/pen through the future screw holes to mark where your going to drill. Hope this helps.

I forwarded your question to an Advisor and they responded with the following: The front doors have a factory 6x9, but most aftermarket 6x9 will not fit because of depth, or mounting height. I would recommend the 6.5 inch Kickers with adapter in the front to match the rest. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Aug 26, 2014 ]  Staff
Everything but the screwdriver. The holes in the adapter they gave me didn't line up exactly with the holes in my CR-V, but I didn't mind drilling a few holes in my door panel :) [ TYLER  Aug 05, 2014 ]
Well that all depends on how you want them installed. Use crutchfields research to see if it will fit in your vehicle. If so, it will screw right in. BUT, if you want to avoid cutting the factory wiring harness you will need an adapter, that usually will be included when you purchase the speaker from here. Just give crutchfield a call or chat online, they wont let you down. [ Jonathan  Aug 03, 2014 ]
If you buy it from Crutchfield and you're just installing speakers, yes. If you're trying to install an amplifier as well, you'll need to buy connection cables separately. But Crutchfield sells that stuff. [ KORD  Aug 03, 2014 ]
yes , all parts and wires ,, covers and screws wire kits come with the speakers. just tell them there for a car,, [ LARRY  Aug 03, 2014 ]
if you opt for the free installation kit offered, you will have everything you need. If you are installing these in the sound bar of your jeep, pick up some dynamat sound insulation for the bar. The bar comes from the factory empty and hollow. any kind of insulation really helps. [ THOMAS  Aug 03, 2014 ]
yes it does they sent me a kit with it and I found out I didn't need it at all and they were easy to install and sound great [ LARRY R  Aug 02, 2014 ]
they come with clips, screws, and wires. if your car requires an adapter you'll get it free from CF. [ D  Aug 02, 2014 ]
Yes if you order from crutchfield. [ JOSHUA  Aug 02, 2014 ]
No... I also had to buy mounting brackets to mount and I also bought the wire kits so I did not have to cut factory connectors.. These items are not expensive.. I installed in a 2010 lx civic.. [ shizzavip  Aug 02, 2014 ]

does anyone have these in a harley davidson??just wondering what they sound like at highway speeds [ jeff  Jun 06, 2014 ]
Frequency response, price and reputation. So far, pleased with purchase. [ STEPHEN  Jan 06, 2014 ]
I have always had good luck with polk audio, and the price was right! [ ADAM  Jan 01, 2014 ]
My van called for 6 1/2 speakers. I didn't know what to buy either. So I went to the local electronics store because they had some on sell. I was lucky they had one sound board working. It all depends on what you like to hear. I thought these speakers had a deep rich sound. The highs were crisp and clean. Plus they are water proof. I did not buy from the local store because they wanted to charge extra for all the hardware, at Crutchfield it was included for free. I bought 4 of them for my pontoon , and 4 of them for my van. These speakers had more bass than what I thought they would. The only thing I need to buy now is a amp. The best speaker I could have bought. I love them. Plus the service at Crutchfield is the best. [ LARRY  Jan 01, 2014 ]
This speaker offers awesome high and mid-range sound quality that you won't find in another speaker for this price. The low frequencies are a bit weak (especially when cold), but when paired with a subwoofer system, these are amazing. [ TYLER  Dec 31, 2013 ]
Beginning with great sound, durability , and super good looks, also a big plus was a great price! [ RAMON E  Dec 31, 2013 ]
The sound is very crisp and the highs are clear as a bell. Friend had them so I got them. You need to run a amp to them for the pure sounds. Trust me you'll love them. [ MICHAEL  Dec 31, 2013 ]
Oh, these polks. I have the db6501's in my truck and love them. Chose these polks for my wife's car because of how satisfied i have been with the ones in the truck. You will be happy with these, not much on bass but very clear sounding [ Jonathan  Dec 31, 2013 ]
I was back and forth with the Alpine's. They both had the same 100w rms that i needed. Mainly went with the polks because they were cheaper. I am very happy with the polks. [ Jonathan  Dec 31, 2013 ]
