Polk AudioDB571 5-by-7-Inch Coaxial Speakers (Pair, Black)

Es el tamaño que trae la bocina original de ford ranger 2010, solo ten en cuenta que los espacios para tornillos no son exactamente iguales, debes taladrar dos nuevos, la bocina suena bien directo a estereo

The speakers sound great, were nicely packaged and a great upgrade for the price.

I bought my F150 used and it came with the "premium" audio option. My last 2 Ford vehicles had the Mach system and my Yukon XL has the Bose system in it. Certainly neither the Mach or Bose is the be all-end all of car audio but they are respectable setups for just listening to music at a reasonable volume.I decided on the DB speakers because a friend of mine who is into car audio and always has a great sounding setup.Install was easy. I popped the speaker cover panels off the truck with a screw driver, used a 7/32 socket to remove the 4 screws holding the old speaker in place, and disconnected the old speaker's wiring harness. Note: You'll need to buy the harnesses for the speakers if you don't want to cut wires, etc. This would make install very quick (probably less than 30 min for all 4 speakers).I ended up cutting the wiring harness plug off and crimped normal speaker terminals on the end of the factory wires. Note that if you decide to do this you need to cut as close to the factory plug as possible because there isn't much slack. Also, the positive terminal will be white with a colored line and the negative will be a solid color with a colored line. Each door has a different colored set of wires as I recall.Two very minor issues during my install was that I had to bend the mounts on each side of the speaker because they wouldn't fit the stock speaker opening and I had to install at least one of the speakers upside down because there wasn't enough slack to turn it the other way. You can't tell with the factory trim piece installed tho.I started with the front passenger door and realized that I ran out of terminals so I had a chance to compare the stock premium speaker with the DB speaker. To test I faded the sound all the way forward so only the front speakers were playing. You could immediately tell the stock speaker had a muddier sound with less definition than the Polk DB speaker. Specifically I noticed backing vocals and cymbals were more clearly defined through the DB speaker. I listened at different volumes as well and the DB speaker seemed louder and clearer across the spectrum than the stock speaker. I could also tell that the overall volume of the system was louder with that one Polk DB speaker.After installing the 2nd speaker the system is noticeably louder than the stock Premium system and sounds much better. Keep in mind I didn't Dynamat or add an amp. Hopefully I'll finish installed the rear 2 speakers soon but interestingly I found that during testing using fade/balance I couldn't tell much difference in sound with the rear speakers going. Its possible that because they're low in the door and there are front seats in the way along with road noise that much of the sound doesn't travel forward.I think the system might be loud enough as is and seems to have enough bass for my needs but I might amp these speakers down the line but for now with the stock head unit they seem to be a noticeable upgrade to the stock premium system.

Great speakers to replace original speakers that failed. Waterproof and good sound. For 2010 Mazda 3, you’ll have to cut the basket, once it is done, they just fit like OEM.

I bought 4 from Fry's Electronics here in Las Vegas for my wifes Ford Explorer. We walked into the store just to browse around and decided to check out the car audio section. We listened to all of the speakers that were connected and these Polk Audio DB571 speakers sounded the loudest and clearest at high levels with no distortion or static. What peaked our interested even further is that they actually produced some decent bass. A lot of door speakers do not, which is why people add subwoofers to their systems. There were some Infiniti speakers there as well but they were a little bit more and the Polk sounded just as clear and loud for less. It was $100 for 2, I bought 4 total ($200). The guys installed them the same day while my wife and I were out watching a movie across the street (Rave Motion Pictures). They called and said they were finished, we went back, my wife started up the truck and as soon as she turned on the radio we immediately knew we got a sweet deal. The difference between the stock Ford Explorer door speakers and these Polk speakers were like night and day. They were a hundred times louder and produced clean, sort of crystal like highs. Certain songs are so clear that the high's can actually hurt your ears because it's as if the tweeters are piercing your ears. That's hwo you know you're getting more than what you've paid for. Being door speakers, the bass wasn't too good. You could hardly hear it. About a week later after messing around with the Sony 660UP head unit settings, which we purchased at the same time, I found a "LOUDNESS" feature and turned it to "ON". Immediately the bass kicked in, and the highs got even higher. The bass still didn't hit as hard as a subwoofer would but for door speakers, they were definitely noticeable and they sounded great. So great, I ordered 4 of these from Amazon to put in my Ford Explorer and now both of our vehicles sound exactly the same with identical equipment. We are both extremely happy with our decision to purchase these speakers to upgrade from our factory ones. No matter your musical taste, these speakers will breathe even more life into the music you've grown up listening to allowing you to relive special moments in your mind that you think about while driving listening to them. If you want to hear music the way was produced and meant to be listened to, purchase these and then go out and get you the best subwoofer that you can afford(we both have a single Hifonics 12" subwoofer in a vented/ported box). Ride hard. Bob your head even harder!
