Inside is laminated with this "ballistic" dynamat knockoff stuff that was kinda cheap from pep boys. Works perfect.
Spikes I had laying around from an old project when I was younger...couldnt really think of anything cool that was free to attach the speakers with so they went on.
Future plans are probably make it bluetooth.
SPEAKERS- yes they are 8ohm. Somehow I thought they were 4.... but they still sound amazing even cranked up.
These instructables helped me brain storm, learn how to pair speakers and amps and build this project and another much larger boombox i'm working on.
