Overview

Our take on the Polk Audio db6501

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 performance

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 versatile db6501 component speaker system features 6-1/2" woofers made from a polymer/mica composite and durable rubber surrounds that won't fall apart under stress from heat, moisture, or time. Liquid-cooled 1" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. You can surface- or flush-mount the tweeters with the included swivel-mount cups. Just aim the tweeters so they broadcast toward your ears, creating a powerful stereo image.

External crossovers direct the right frequencies to the tweeters and woofers to maximize their performance, and their housings let you hide all wiring for a clean, professional look. 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.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Great sound reproduction for the price. Tuned right these speakers will sound awesome.

Product Research

Woofers
Tweeters
Crossovers

Woofers

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 Formers: The low-mass 2-Layer 1" Kapton Voice Coil formers are lightweight for high sound output. Kapton's high melting temperature ensures high power handling and excellent reliability.

Pole Plate Heat Sinks: The pole plate heat sinks promote better heat dissipation for superior power handling and reliability.

Mounting Ring: The supplied mounting ring has mounting holes for both 6-1/2" and 6-3/4" applications, including GM/Chrysler 6-3/4G, allowing the speaker to fit more vehicles. In most cases, the ring should be used to mount the speaker.

Tweeters

Silk/Polymer Composite Tweeters: The 1" liquid-cooled, silk/polymer composite tweeters provide clear, detailed highs.

Mounting: The supplied mounting cups allow you to surface- or flush-mount the tweeters. The tweeters swivel in the flush-mount housings, allowing you to adjust them for optimum imaging.

Tweeter Mounting Dimensions:

  Surface Mount Flush Mount
Mounting Height 1.046" 0.364"
Depth 0.825" (screw depth) 0.938"
Frame Diameter 2.002" 2.297"
Cutout Diameter N/A 1.951"

Crossovers

2-Way Crossovers: Each Butterworth outboard crossover features a 12dB/octave high-pass network for the tweeter and a 12dB/octave low-pass network for the woofer.

Tweeter Attenuation Switch: You can adjust the output of the tweeter to match a level appropriate to your vehicle or your system. On the end of crossover (opposite the terminals), the tweeter attenuation switch can be set to 0dB, -3dB, or +3dB.

Electronic Tweeter Protection Circuits: Each crossover has a built-in protection circuit that guards the tweeter against accidental damage from high power.

Crossover Connections: The crossover inputs and outputs are screw terminals. The crossover housing is vented, giving you a choice of hidden wire channels for easier, more professional-looking installs.

Mounting: There are two mounting holes in the base of each crossover.

Crossover Dimensions: L=5.029", W=3.072", H=1.075"

I've been getting some advice on what speakers to use from a good friend of mine and chose Polk Audios since they are one of the best speakers to buy. I saw the price reduction, about 80 bucks from it's original price and had to take the opportunity while I still had it. I can't wait to get my hands on these and hook them up. So many great reviews on Polk Audio systems as well. [ Anthony  Dec 14, 2015 ]

Great sound and some mods will fit with roll cage. [ William  Dec 03, 2015 ]

18 questions already asked

I don't believe we have researched that vehicle, if it is not sold in the U.S. we probably won't have any information. Otherwise I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Kenny  Apr 21, 2017 ]  Staff
We do not research all motorcycles for radio & speaker fit. The 6.5" midbass drivers are a standard size and should fit a factory 6.5" speaker mount that has an available depth of around 2" or more. The crossovers and separate tweeters would require custom mounting. The tweeters do come packaged with both surface & flush mount brackets to help with the installation. You will find this information, and more, by clicking the "Details" tab on the speaker's main webpage and scrolling down below the "Features & Specs" table. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5 [ Ryan  Jun 29, 2016 ]  Staff
You can run them off your head unit but they will be seriously under powered I would suggest an app that is capable of pushing enough power to them. If you do decide to just use the head unit that will not hurt the speakers and they will still sound good, but they will never live up to your full expectations. [ Shawn  May 13, 2016 ]
YEs you can run it either way [ Ofari  May 10, 2016 ]
The 6.5" midbass drivers have a top mount depth of 1.9". You will find this information, and more, by clicking the "Details" tab on the speaker's main webpage and scrolling down to the "Features & Specs" table. You can also see if they are a recommended fit in your vehicle by using the "Outfit My Car" application on the main Crutchfield website here: http://www.crutchfield.com/car/carselector.aspx?lp=%2fCar%2foutfitmycar%2fcar.aspx I hope that helps!

Install them in my 2001 Silverado with factory head unit and I am extremely pleased with the sound quality. [ Wayne  Dec 21, 2015 ]
Nends more power. They definitely sounds better than stock, but at higher volume levels get distorted. [ Shawn  Dec 21, 2015 ]
I have been using these speakers in a jeep connected directly to the radio without amplifier and sound quality is very good. Good luck. Gilberto [ GILBERTO  Dec 21, 2015 ]
really nice speakers and 40 would fine. I ran mine with a Rockford fosgate p300x2. Sounded amazing in my 370z. They love to be pushed hard and really come alive at the higher wattage so if you are running an amp I'd look at a bigger amp for a cleaner signal at 40 watts. [ ANDREA  Dec 21, 2015 ]
I forwarded your question to an Advisor and they responded with the following: The Polk db6501s model of speakers is free air rated so they don't have a cubic feet measurement recommended. They are rated as such so they can sound good in all types of vehicles with all different cubic feet measurements for the door. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Jul 29, 2015 ]  Staff
Thanks for your question. Our area of distribution is limited to the U.S. (including Puerto Rico, APO, and FPO locations). [ Krissy  Mar 24, 2015 ]  Staff
Well I install my tweeter in the door of a 1968 Camaro and the crossover box were install in the trunk with the woofer, as for the speaker you can run the wire from the A-pillar to the door, and put the wires in the boot for door locks or power window ......I hope that help . [ PAUL  Feb 09, 2015 ]
The x-over has 3 pairs of connections. The amplifier connects to the "input", the tweeter and woofer then would connect to their appropriate labeled connections. You will probably have to install your own wires between the x-over and the speakers. Unless you can locate the factory wires at a common location. Be sure to locate the x-overs in a dry place, not inside the car doors. [ KENNETH  Feb 09, 2015 ]
These are not marine rated speakers. For those kind of speakers you'll want to check out the marine speaker section of our site: http://www.crutchfield.com/m_216950/Marine-Speakers.html [ Jeff  Jan 02, 2015 ]  Staff
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. [ Krissy  Dec 26, 2014 ]  Staff
Quit powerful and more than enough for my truck, had it professionally installed [ TONATIUH  Jun 29, 2016 ]
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Krissy  Aug 27, 2014 ]  Staff
As far as which speakers to pair them with I can't help you talk to an advisor they would be able to but add far as steering wheel controls if you use a factory adapter when installing a new head unit most of them will have a plug for a programmable switch. [ Shawn  May 13, 2016 ]
Hi Robert, My system for a 2000 Mustang GE Convertible consists of the following Polk Audio db5251 5-1/4" Component System Polk Audio db6501 6-1/2" Component System Clarion XC1410 Compact 4-channel car amplifier - 50 watts RMS x 4 105KDAHD79 JVC ARSENAL KD-AHD79 CD HD Receiver lots of wire and cables I'm thrilled with the system. My car is doesn't have steering wheel controls and that's why I liked the fob-CD-receiver control that came with the JVC Arsenal receiver. The AMP is small in size and big in power. I took my time installing everything and rewiring the system over a long Thanksgiving weekend. Love it! [ GEORGE  Jul 22, 2014 ]
I went with the db651 rear speakers and am happy with the sound. I cannot answer your question about the amp and steering wheel adapter as I did not change those components. My amp is built into my receiver. [ BRADLEY  Jul 21, 2014 ]
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with these speakers. They will be able to pull up your vehicle and see if what will integrate. If it does not, then they will also be able to discuss other options with you. [ Greg  Jul 21, 2014 ]  Staff
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. 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  Apr 05, 2014 ]  Staff

It is 100 watts rms for each channel. 100 for the tweeter and mid on the right side and 100 for the tweeter and mid on the left side. I ran them off the deck only at first, and was not impressed, but once I put an amp to them, they sounded great. [ CHRIS  Dec 26, 2013 ]
Power Handling: Peak: 600 watts per set / 300 watts each side RMS: 200 watts per set / 100 watts each side [ MARK  Dec 26, 2013 ]
To be clear, let's call it 100W rms per channel. One channel consists of two drivers: mid/bass driver and tweeter. Together, they can handle 100W rms. They are not set up to bi-amp from the factory, but if you had an electronic cross-over, you could do it...just don't know what rating is for each driver. Does that help? [ MICHAEL A  Dec 26, 2013 ]
The RMS wattage is per speaker. I have a 4x100 amp running mine. Each speaker has it's own channel so the fade and balance still work like stock. The set up sounds great! [ MICHAEL  Dec 26, 2013 ]
It's is per speaker. [ JOSHUA  Dec 26, 2013 ]
The speaker isn't built to be mounted that way but you can do it. The tweeter will sit in the sunken front of the grill and you will either need to come up with your own mounting clips or hot glue the tweeter to the frame. If you are planning on leaving it exposed, it might not have a finished look unless you plan on doing some creative finishing with paint or fiberglass. [ Mr.  Dec 20, 2013 ]
Probably but not without risking the structural integrity of the grille and speaker. I don't think its worth the risk.There are other speakers available that are designed that way. Return them and order new onet. Cruthfield is very helpful when you clearly describe what you want to do. [ MARTIN R  Dec 20, 2013 ]
