I installed them on the center console of my 13ft Boston Whaler with a Rockville head unit. her where I think it matters. I went cheaper with my boat because it will be close to salt and water. They don't sound very good, but they're loud enough for what I want. They're not the worst quality, but don't expect 4-channel sound from them. They don't sound as clear as if you would hear them with a good speaker, but I wanted waterproof and cheap ones and that's what I got.
