Speaker hack for bosch powerbox jobsite radio.?
I have a bosch powerbox jobsite radio. Under normal conditions it is sufficiently loud. The problem is I don't use it under normal conditions. My jobsite is particularly loud on top of the fact I have to and choose to wear earplugs. This makes it very difficult to hear my radio. I want to be able to make a small box with a low, mid, and hi perhaps and use the outgoing auxiliary jack to supply the music. I'm not sure if the radio continues playing though or if it just uses whatever device it may be hooked to. It would also be more convenient if the box was somehow built to hang off the roll cage of the powerbox. I feel I have a decent Idea here but lack the knowledge to bring it to fruition. I'm open to any and all suggestions although I would like to stay close to my initial inspiration. Thanks everyone in advance.
