Project Description:
This is an original drive-in movie speaker rig I picked up with the intentions of modifying/modernizing it for Bluetooth capabilities.
Design Goals:
I wanted a completely wireless, mobile Bluetooth speaker set up to take anywhere I want to go. I loved drive-in movies and thought it would be awesome to freak out family and friends when I fire this badboy up!

PC105-4 4″ poly cone speakers

Speaker holder (top of pole )
Crossover Design:
N/A
Tips & Tricks:
No tips or tricks needed, just have fun and use your imagination.
Conclusion:
I did not want to sacrifice original speakers or the housing so I made my own control panel from 26ga. sheet metal. All wiring runs up through the housing using existing holes. I used Velcro to secure the circuit boards to the housing. The control panel is a simple 3 3/4″ x 4 1/2″ x 1 1/4″ deep box that I made and is secured to the top of the pole via 2 screws with nuts and lock washers. The speakers attached to the original housings with no modifications needed!

VERY COOL! It brings back memories of going to the drive-in with my family. Making and taking our own popcorn in grassy brown bags. Dad drinking who-knows-what. I think I saw Bullitt at the Crescent Drive-in, in Danville VA.
I’m just starting to learn about speakers and like that I can incorporate some art into speakers as opposed to boxes. Man, you just got me excited to create something cool too.
Awesome!
