The PDP-E800DSP is extremely versatile and flexible- it can be added-on to virtually any factory or aftermarket car entertainment system to build the sound system you require. Connect the DSP amp to your factory system throught the 6-channel speaker-level inputs with remote sensing, or alternatively, use the 6-channel pre-amp input (RCA). There is also an Optical input (max 24bit/96kHz) to connect additional sources.
