The fact that it is made from Stainless Steel is of major importance for longevity. Easily installed and plug in to radio for ease of connection made install quick and simple.

    Good speaker

I chose this because of price and size. It is exactly what I needed. It works very well. My radio is mounted in an electronics box on my t-top this allows you to hear the radio without having to keep the door open.
