The 1973–1987 Square Body has a single DIN radio opening that accepts modern head units with no modification. Here are the top picks.
Square Body Radio Opening
The Square Body uses a standard single DIN (2" x 7") radio cavity. Any modern single DIN unit drops right in using a universal install kit. Double DIN requires a dash cut and custom bezel.
Best Single DIN Options:
1. Sony DSX-GS80 – Best Sound Quality
The Sony DSX-GS80 is a single DIN powerhouse with exceptional amplifier power (55W x 4), Bluetooth, USB, and no CD drive (smaller footprint). Sounds incredible with upgraded speakers.
2. Pioneer DEH-S7200BHS – Best Features
Pioneer’s DEH-S7200BHS delivers SiriusXM, Bluetooth streaming, HD Radio, and iPhone/Android compatibility in a single DIN format.
3. JVC KD-X280BT – Best Budget
JVC’s KD-X280BT is a no-frills Bluetooth media receiver at a budget price. Great for basic Bluetooth streaming use.
Going Double DIN:
If you want Apple CarPlay, consider the Kissound 7" Double DIN unit. You’ll need to cut the dash opening, but the result is a full touchscreen CarPlay/Android Auto experience.
Speaker Pairing:
Any of these head units sound great paired with a set of 6x9 speakers in custom pods or door locations.
