## Questions & Answers

**Q: Does this include everything needed for line out conversion from a factory unit or do I need a special wire?**
A: No, this takes rca in, all that's in the box is the dsp,a green adapter for power ground remote wire and the instructions. You will also need to buy a inline fuse for it(0.2mA fuse)

**Q: Can u play your music thru the Bluetooth on this device?**
A: No, the Bluetooth on this is just means to control DSP settings from the app
