The Class D RL-LA600.1 efficiently delivers the power to drive a DD AUDIO loaded enclosure or DD REDLINE multi subwoofer setups. Bandpass crossovers and bass boost capabilities allow precise tuning of the sub stage while the included remote control knob adds the ability to make on the fly adjustments of the subwoofer volume. 

When paired with a DD AUDIO SC2 or SC4 active line output converter, the REDLINE LA Series amplifiers provide a seamless factory integrated amplification solution.

The REDLINE LA Series amplifiers utilize spade terminals for clean and secure connections on both the power input and speaker outputs.
