Ordered 2 sets of the 5-1/4 one for the for the front speakers in my Jeep Tj and another set for the rear sound bar. Installed easily and had the wires and screws in the box. Great sound waaaay better than the factory ones.

Speakers arrived with no fasteners...requires self tapping, coated screws with tiny heads (in order for them to nest in the recess well molded into the plastic shroud/grill.) Even Ace Hdwe did not have the proper fastener, so had to improvise. Also. No instructions of any kind. Since these Polk's were 2 1/2 times the price of the Jensen's in there previously you'd think fasteners would be included.

Big picture is good value from a well known brand. My aftermarket radio doesn't provide the best sound, so not totally certain on the sound quality.

Bought these to replace stock speakers on an Indian Motorcycle with loud pipes! These things rock! Ive had them up high enough that my buddy could hear them over his straight piped Harley! No distortion like stock!
Replaced the old speakers in a 2008 boat. These have good highs and put out a tight bass. You can definitely tell a difference. They do not distort when you crank it. Happy customer
as a huge Polk Audio fan I was a little disappointed by the sound quality my cheaper Sony speakers I was replacing sounded better. For the price, they were ok I'm just used to better sound from polk, even at this price point.
Bought these for their sound quality and high decible rating cause i needed my front stage to be better and it worked! They out performed my pioneer coaxils with more volume and richer sound! I am running a 4 channel amp so front channels run all 4 front and rear coaxils and factory door tweeters. And rear channel runs my subs! Very clean and sounds great. Hi powered deck wasnt quiet enough, so i opted to dump fader ability! So the polks gave me that extra volume for my front speaker fill! And they sounded better. Turned out to be a win,win!
Excellent sound and decent base with the Motorcycle Fairing as the shell/box.Paired with theKenwood KAC-M1824BT Compact 400-Watt Bluetooth Amp they have made my rides more enjoyable and the price was very fair for the quality that they reproduce from mp3's
put them in my jeep, i did need a bracket to fit them as i was replacing 4x6 speakers with these. they sound way better than what i had.
I installed these on my 2014 Indian Chieftain.The sound quality over the stock speakers is marked better.I normally listen to music that I have on a flash drive and I couldn't believe what I had been missing using the stock speakers.I do have to turn the volume up 1 notch though.
