    They sound great, I put them in my maverick X3 and they are amazing. I’m ready to buy 2 more.

    Little guys make a big difference

    Mounted these inside a custom pvc facing with back support, firing forward under the gunwale. I also have two 6.5” firing toward the aft under the helm and under the dry box. The two firing aft weren’t enough, but the 2 additional 4” have provided enough clear sound at a comfortable volume to hear clearly under way, as they use the acoustic environment of the hull to project their sound. 10/10 exceeded my expectations. These made a huge difference. I have to hit it with a 3 on value, as they’re priced at the same point as their bigger, better made counterparts. I would definitely recommend in a small spot though
