this is a simple way to add permanent speakers to your disc golf bag, would also work well on a back pack or any other bag. this project took me less than a half an hour, it is very easy, and the results are very satisfying.
I've tried several different speaker setups on my disc golf bag, and I've had problems with speakers falling out, or being muffled by my bag, or I had strap mounted speakers and they would continuously change speakers directions causing muffled sounds. so mounting the speakers in a way where they will not have anything blocking them is a big benefit, so far I found this is the best way to go.
Step 1: Get your things together
Speakers, I used Phillips multimedia speakers 2.0 LINK
Disc golf bag, I have the Fade Crunch box
the speakers run about 20 bucks, however I found mine on clearance for 10 at TJ Max.
