$48 Bluetooth sound bar (for home entertainment). Can not believe how well it works. Very loud with little distortion at max volume. Not waterproof but it got rained on quite a bit. I just spliced a 12v cigarette lighter plug to the power cord. Mounted with two 1-1/2" "minis" or conduit clamps from Lowe's. Works perfect for me because I just wanted to Bluetooth my music from my phone anyway.
