Most units support common audio formats such as MP3, WMA, WAV, AAC and FLAC. Some models also list video or advanced codecs—examples include H.264, WMV, MPEG‑1/2/4 and MKV. Exact format support varies by receiver model.

Most CD receivers accept standard audio discs (CD, CD‑R, CD‑RW) and can play audio files burned to discs—commonly MP3, WMA and AAC. Those same file types are often supported from USB sources as well.

Power specs vary by model; many list a 50‑watt maximum per channel ×4, while some show a four‑channel amp rated at 4×55W. Reported ratings depend on the specific unit.

Typical connections include USB inputs for audio playback (and on some units USB charging), front USB and auxiliary inputs for sources, RCA preamp outputs for adding amplifiers or subwoofers (examples: 2.5V, 4.0V or 5.0V preouts and multiple preouts), plus video or backup‑camera RCA inputs/outputs on certain models.

Head units are available in single‑DIN and double‑DIN formats. Double‑DIN touchscreen examples in these results include 6.8‑inch WSVGA and 7‑inch screens, while single‑DIN models use smaller multi‑line or VA LCD displays.

Connection capacity varies: some receivers offer dual Bluetooth so two smartphones can be connected simultaneously, while others allow multiple device pairings for switching or shared streaming—examples include units that pair up to five Bluetooth devices for music rotation.
