    • Good product and good price.
Color: Black
Perfect for my golf cart with a small amp. I can't believe how loud they get on a golf cart and sound pretty good.

I really like these speakers. They produce loud clean sound. Easy to install and affordable. I thought installing them low to the deck like in the picture. Would rob them of their potential, But I was wrong. Still clean and loud. I went with an amplifier to install them with. I would suggest the same thing for anyone else to do the same thing. Trust me you won't be disappointed. ... show more

Love the speakers. Bought them 5 months ago and had my radio shop install them 4 months ago. But the right speaker tweeter has already gone out. Now i'm already looking to replace the speakers... So sad...

100% deff recommend buying these, they fit nice and clean on my rzr cage, I didn’t wanna spend 300-700+ I opted for these and they came out better than i thought, once the speaker goes out I’ll just replace them with some better ones but for now it’s perfect!

    • Great for the price!
Color: Black
I got these to put on the roll bar on my 87 4Runner. Really wanted something waterproof for when I take the top off in the summer. Had them on for a few weeks now and they sound great! Easy to install. Haven’t been able to really test the waterproofing or durability yet. But for the price, can’t really beat them. ... show more

    • Not Great
Color: Black
Purchased them last year for my boat. They performed ok on first use, sound quality not great. The next weekend they no longer produced sound. Thought it was my amp. But connected them to a known working amp and still no sound. I was able to get a replacement from the company. Got the replacements installed and sound quality is the same, not great. Turning them up to good volume has them sounding distorted. I have 6.5 Polk marine in the boat and they are connected to the same amp and sound awesome at same volume. You get what you paid for. ... show more

    • Decent quality for low price
Color: Black
Easy to install, flexible mounting, seem well built. Not truly swivel as they can't be turned once installed (mount swivels to allow different angles between clamp/speaker direction when installing, but fixed once installed). Quality is what you expect for $100. Had to open up the enclosures and dump out plastic shards left in there from manufacturing (to avoid them buzzing when music playing). Overall satisfied, we'll see how long they last. ... show more

    • Mounting hradware
Color: White
The mount to hold the hex nuts in place rounded out with simply hand tightening, Would recommend a washer and a lock nut. Decent speakers for the price, but the mounting needs reinforcing. Went with washers and a lock nut. Worked fine
