Polk Audio DB402 DB+ Series 4 Inch Speakers Car Audio with Marine Certification, Car Coaxial Speakers, Black

these work great in an old toyota pickup and the price was right

I bought these speakers to install on my goldwing. They sound good and fit into my old speaker housings perfectly. For the money I am happy with the item.

Using these speakers as an upgrade in a Spark 40 desktop guitar amplifier. Definite improvement in balancing out the audio spectrum versus the stock speaker performance. Perfect fitment and easy to install. Includes all wiring and mounting accessories needed for a variety of applications. Familiar with Polk products for a number of years, trust their build quality and faithful musical reproduction. Pricing represents an unbeatable value - an additional positive note for choosing these. The Polk DB402 DB+ speakers are certainly another fine model of Polk's exemplary offerings!

They're pretty good speakers, but you need to put a bass choke on them, or else you're going to blow them up because they can't handle the bass.

I used these to replace the 3.5 inch speakers in the rear pillars of my 2018 Ford Explorer. I wound up cutting the plastic basket off of the factory speakers, then trimming and sanding down the plastic gasket of the 3.5 inch to mount these in the factory space. They sound excellent, being fed by an amp that puts out about 75 watts to each speaker. The fit was very tight, but I wanted to keep with Polk Audio since I have swapped out all of the door speakers and tweeters with Polk already. Polk Audio does not currently make a 3.5 inch speaker so I took my chances with these and I made it work out.

I bought these to add to the saddle bags of my cruiser and I have nothing but great things to say. These speakers sound amazing and were incredibly easy to mount and wire. Once they were installed they make some noise. I pretty much have surround sound even when I am riding. They are strongly built and made to last. There is no cracking sounds or issues when the stereo is turned all the way up. They have a nice deep sound and the bass is clear as crystal. If you were considering buying these puppies, go ahead and get them.

I'm very impressed, I just wanted to install a few cheap speakers to listen to podcasts/maybe light music but these far outshined my expectations. I'm not saying it's a complete 'system' but these sound really good, decent bass, and they output insane volume for the size. I'm very impressed.

Seem to be used packaging was a fluttered and could tell they were hooked up by the bent pins on speaker connections. I thought it was a new item.
