Great job 08 & TWS!!!! I will dive in an check out my harness tomorrow.

Thanks guys for diving in the deep end on this!!!

OCD kicks in and I can't sleep till I figure it out.... Thanks for everyone's help!

 

FYI, I got to the house to verify my harnesses and stereo. My harness is wired exactly like you guys harnesses and I'm in stereo.

Low level input off DSP.

Thus it must be something other than the input wiring harness at the amp plug in.

08 is going to research more tomorrow.

Was this so called mis-wiring issue confirmed thru Focal?
I have a brand new amp sitting here and inspected both the high level and low level input plugs and they are wired the same with the - of the left channel and the + of the right channel at the plug going into the amp.
I would not suspect that both the input plugs would be wired incorrectly.
Without having a schematic of the printed circuit for the inputs or disassembling the amp and tracing the board to verify what input pin went were I myself would leave well enough alone and not risk burning up a high dollar piece of equipment by experimenting and cutting wires to wire as you think it should.
Just my thoughts.

 

About two weeks ago I asked Focal for a connector schematic to check the pin-outs but never got one. My first email response from them was last Friday. Holidays I guess.

Wouldn't be that likely but perhaps the 2017 Ultra factory wiring harness is different from the 2014's?. Or maybe the Amp output harness is mislabeled? As 08FXLD pointed out, the Focal wiring diagram from the install manual is incorrect. I'm not using a DSP or anything but I was full mono until I swapped those Amp input wires for both the front and rear. Stereo now. Looking forward to what 08 comes up with...

 

How do you have this wired on the input? How bout the output?

On the input I'm using low level and it's wired exactly like all of our harnesses. The RCAs were carefully checked to make sure 1/2 & 3/4 were all plugged in to the intended Focal input from the ARC DSP harness.

On the output I clipped the molex plug off and simply followed the color pairs as I am running all non OEM speaker wire.

It's either a wire crossed upstream of the amp input harness or it's one of the molex plugs on the rca side of the input harness. Could also be OEM speaker wire to Focal molex cause the wire colors coming out of the amp are legit.

U running BT355s?

Lets just say I need this amp. lol Where is the best place/price I can get one? Thanks.

 

best price i have found so far is pacific stereo in CA, 699 i believe.

I'm looking too, just trying to figure out what's going on with the harness before pulling the trigger, and trying to confirm if I need one or 2 or any BT355 ?

If you have a Rushmore are you having the head unit flashed for 4 channel or just going to use 2 channel input.
If you are just going to use a 2 channel input then you will only need 1 BT355

 

[QUOTE=Babyboy;16978785]I was figuring on doing the flash, plan is one amp 4 speakers, lids and fairing 2018 SGS
