This is awesome! Greatest purchase ever! I rigged it up on my golf cart at work and scared the snot out of my coworkers! Volume is LOUD! Very easy to install (keep in mind I’m also an electrician) very durable, well crafted! I’ve seen these go for upwards of over 100$ but this is the best thing I could have bought for it you get the best value for your money! Compressor is shocking for a 12v but worth it! ... show more
