Rockford Fosgate 3Sixty.3 8-channel digital signal processor

Rockford Fosgate built their 3Sixty.3 processor so you can enjoy amazing sound quality from your vehicle's sound system — the quality you'd expect from a high-fidelity home stereo system or a pair of really good headphones. This sophisticated signal processor works with your laptop to give you awesome control. Once you load the software from the included setup CD, you can connect the 3Sixty.3 to your laptop with the included USB cable, and get to work creating a perfect-sounding system with the user interface controls displayed on your computer's screen.

Setting up

The 3Sixty.3 can handle up to 8 inputs, whether they're line-level signals from an aftermarket receiver or speaker-level signals from a factory radio. You can set the input signals to combine together or stay distinct, and then assign them to up to 8 output channels. The setup CD includes a track to help set input levels and another track that's used in the "Auto Normalize" feature that flattens the entire system's EQ response curve automatically. The remote amp turn-on connection features an adjustable delay, so you'll never hear a pop when you turn your system on.

Add sources

The 3Sixty.3 lets you add sources through both auxiliary RCA and TOSLINK optical connections. A wired remote control lets you switch between main source, auxiliary input, optical, or a Bluetooth® enabled device. The Bluetooth feature can be set to "Auto Play," which automatically switches the source over to your Bluetooth device when it sends out a notification or plays music.

Central control

The main user interface screen displays your speaker configuration, a wired remote simulator, an EQ graph, and the EQ controls. Each of the 3Sixty.3's 8 channels has its own crossover network, level adjustment, delay setting, polarity switch, and 31 bands of equalization. You can link channels together, if you want them to have identical EQ settings.
