Ordering parts for 8k OPS

[HongJu1009]

Hey guys so I'm planning to retrofit 8k OPS in my car I've listed out a part that i will buy, can anyone confirm that these are the correct parts?
Sensors: 34D 919 275 x4
Brackets: 5GD 919 493 x4
OPS module: 7E0 919 475J x1
OPS switch: i can't seem to find the 6ru one anywhere, will 6RD927122 work too?
the wiring I'm planning to buy a ready made one from china so i won't have to mess with too much things and just plug it in for the most part
anything else I'm missing?

Throw in a couple of speakers and you're good to go, I'd say.

I'm looking at 5Q0 919 279 now, how many do i need, just one?

[iichel]

You will need two of them; one in the front and one in the back. The part number depends on your wiring (connector). The number you mention should probably be fine.

alright, my car originally have 4k OPS, so i only need one at the front right?

[iichel]

This is correct, however, make sure the old speaker is compatible with your new wiring.
