Bose pre-out harness adapter

mpkayeuk

I have a 2010 40th Anniversary with Bose and Connect Premium, etc. I want to keep the factory head unit for obvious reasons. This is NOT negotiable, so no recommendations for aftermarket HUs please guys

What I'd like to do is feed the Bose pre-outs into an Audison Bit One (also, non negotiable) for EQ, etc. Does anyone make a harness adapter so I don't have to splice or cut the factory harness. I envisage taking the pre-out at the Bose amp input end, and adapting the harness there for input to the Bit One.

My understanding is that the Bose amp has a base EQ profile tailored for the vehicle and that the EQ controls on the HU are in addition to this base EQ. Is my understanding on this correct? I know with the Bit One I can achieve a relatively flat response quote easily as a basis for EQ, but I wanted to know how unmolested the pre-out signal is from the HU in the first place.

Informed answers welcome folks
