    • Great Speakers
Style: Marine Certified
Upgraded my speakers in a 2014 F150 both front and back. These sound 200 percent better than the cheap 25 watt Ford factory speakers that come with the truck. I kept the original radio and had no problems.

Delivered quickly. Amazing sound. Greatly made and really cheap. Did have to modify them a little to fit my speaker lids but not hard to do. Love them.

Replaced Boss speakers in my hot rod that could not handle any base. Installed these and sound great with no issues. A few dollars more go a long way. The do not come with grilles, so be prepared...

    • Good saddle bag install

Put these in my hard leather saddle bags. Equalizer brings out decent bass and the sound is clear. You can’t get great out of saddle bags, but it’s pretty good. I covered with stainless steel plates that I got from Amazon, wrapped the edge with door edge guard. Very pleased.

    • Fits perfectly in my 2013 F-150 XLT Supercab
Style: Marine Certified
Doing research I found that my truck required 6x8 speakers, but found out that the 5x7 speakers should also be able to accommodate the same mounting holes. There isn't a ton of boom to the bass, but it's way better than the blown speakers that I had before :D I would highly suggest getting a wiring harness for the Ford F-150 trucks as it made installation a breeze. I purchased these for my truck: https://www.amazon.com/dp/B001OAB6BW ... show more

Style: Marine Certified
They don’t have much bass but I have a crossover at 300 so wouldn’t know. The highs are good. Time will tell if they hold up. UPDATE well less than 3 months one snap crackled and popped dead so for the price you get 1 speaker

    • Replacing older model polks
Style: Marine Certified
I blew an older model Polk speaker. I bought this pair and they are working great. Sound awesome. They bolted right up as a direct replacement. I recommend buying the pigtails to not cut your factory harness.
