Technic harness and RCA's

I hoping someone can help me out.

I bought a new but second hand Technic harness for the base stereo with i-drive for a E90 with the view of fitting it to a F10 with pro nav but base hifi.
Base being the 6 speaker system comprising 2 subs, 2 front and 2 rear speakers – generally found in Europe, Canada and Asia.


The harness is as per the link below

The harness is slightly different as it is pre wired for an MS8 with 16 pin molex’s on each of the cable runs from the quadlock to the boot(trunk).


My views of using an MS8 now have now changed and I will either use a 5 or 6 channel amp instead. The amp will have RCA inputs and I plan to code the head unit to hifi.

However I’d like some advice to the best approach.

Option 1
Should I seek out a 16 pin female house and have it pinned up to allow it to mate to the 16 pin already on the technic cable runs?

And attach a custom made RCA harness similar to the below.

Or

Option 2
Am I better to cut off the molex and attach RCA’s direct to the cables?

Any advice is welcome, as my knowledge of car hifi and any potential flaws in the above two options is limited.

I note that Technic can sell a quadlock to amp cable which has a twisted RCA cable run.

Thanks

Your first problem is you referred to your system as "base hifi" in as few words. "Base" (stereo) and "hifi" are two completely different systems with highly different physical architecture. Though you seem to understand the difference later in your post. :

The screw terminals might work, if inelegant. Personally I would wire up speaker to RCA connections (JL audio sells this).

The twisted pair harness by technic will have better results if you are recoding to Hifi; the low level signal is prone to pick up noise along the long run from head unit to trunk without twisted pair (I have personal experience on this matter).

Thanks Taibanl

I'll follow your advice.

Twisted RCA's found :

I just need to indentify the type of crimp connectors used in the harness.

If anyone can help that would appreciated.
