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.
Step 2: Practice
Step 3: Time to Mount Them
next cut a hole in your bag large enough that you can fit the front of the speaker through it, but not too big, should be a semi tight fit.
the nice thing about this is that your cuts don't have to be perfect, cause once you mount your speakers you'll never see the cuts again. main thing you need to do is make your hole is large enough so that the screw holes clear the fabric, you might have to do a little extra trimming to make it work.
next replace the screws and position your speaker how you'd like it and tighten the screws, and that's it, repeat for the other speaker.
