### ⭐⭐⭐⭐⭐ Review
*by J***M on 2 August 2023*

First off my expectations weren't that this thing was going to go down the road shaking other peoples cars or scaring old people! Realistically I needed something to bring back the low end to my music as I drive a Jeep Wrangler JKU ( all the carpet removed from previous owner ) with 37" aggressive mud tires, with the top off and on the highway you couldn't even hear the radio. Problem solved! First off the stock stereo on jeeps aren't anything to test this thing with. (They are pretty cheap, useless head units.) That said, I won't have to run out and get a new stereo and replace the stock speakers right away. This little thing does everything I need it to. Huge improvement to the stock system. It's not going to impress anyone who's running amps and 15's, but this little thing surprised me, and for it's size and for the price you can't beat it. If you're looking for something to give you just a little more bass this will do just that. I listen to mostly hard rock and metal even with the blast beats this speaker hits pretty well. Haven't had any issues with it overheating, and I have taken it on several 4 hours trips blasting most of the way. Thought about adding a second one, but it's really not necessary , will see how much better this thing does when I update my stock system. But for now I'm happy with it.
