Subwoofers in a cruiser mopar
I bought a Pioneer Bluetooth receiver, no cd, mounted at the bottom of the dash with some angle brackets.
Wrapped it in a black, breathable, material I had for hanging dryer vent.
Hardly noticeable, unobtrusive, and I kept the radio plate.
Used a marine antenna, nothing on fender.
Built kickpanel 6" speaker mounts out of the small drywall mud containers, covered them in thin black carpet/felt.
Built a small bracket for 2 smaller speakers in the dash.
Reworked 2 old home speaker boxes for the rear, installed 6x9 three way speakers, mounted to rear fastback floor.
