  • Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)
  • Maximum Output Power: 50 watts x 4 channels

6Ch/2.5V Pre-Outs + Sub Control: The DPX504BT is fitted with front, rear and subwoofer 2.5-volt pre-outs. The front and rear speaker preamp outputs are balance and fade adjustable. The subwoofer preamp output is non-fading and features independent level control (-50 to +10).

Vehicle Settings: In order to optimize the sound quality in your vehicle, you can indentify the type of vehicle you have, select speaker sizes & locations, as well as configure listening distances.
