I’ve got A 2014 Mazda SP25 GT with factory Bose audio. The factory amp is under the seat and I am planning to delete it and put in a Helix P Six DSP MK2. This amp has high level inputs and line inputs (RCA).

My hurdle is I’m keeping the OEM head unit which has no RCA outputs. Upon some research, the head unit outputs a Low Level Differential signal to the factory amp and I am a bit confused on whether or not I connect the outputs of the head unit to the high level input on the helix or if I splice and solder RCA’s to the OEM speaker wires that normally go to the Bose amp and route them to the helix Line Input.

I feel I should be soldering RCA’s and using Line input but it does feel a bit dodgy. How would you go about it?

Thanks!
