Party cove gansta

Running 4 of these 2 white n 2 black in the back. On a pontoon. Let me tell you we are bringing new meaning to party cove! These sound great and with plenty of power to them our little yacht club of sorts can all jam out on one boat.

DIY Water Proof Boom Box

Used this speaker in a DIY build and it sounds great. I mounted it in a Apache 2800 case. I have it ran off of a mono 100w chip amp and 24v. It sounds great, far exceeds my expectations for volume, clarity and bass response. Not to mention its a marine speaker so its right at home at the pool, beach or on the 4 wheeler.
