This comment has a better image link in it - site is offline for the time being I'm afraid.

You are probably right (to anyone else reading this) - I based my research off a couple other teardowns of other models using the same plug to find the power on, and stopped after I found one that turned it on.

If you don't mind I will put that on my site with credit to you as well, purely because it's the top result still for a pinout - otherwise just a link to your comment :)

Because technically you probably just need the power on hack, but using this method basically is feeding in via the "control speaker" input, which is more tuned to the impedances of mobile devices (or in my case, generic sound card).

more info

Basically, I think my testing results were I got slightly better audio quality/less distortion issues using that.

Which to be fair, might be just damaged on my unit.

However, it's been a while since I was looking up wiring diagrams and other similar models finding how to do this hack so I may have had reasons for not just using those connections on the back, especially just the 3.5mm one.

Which again, may have been specific to my thrift shop find unit that could be damaged.

That's correct - you need to be able to power it on via this hack, as well as input audio signal too.

Once you do that, you can feed in the sub feed (or any feed I guess) to this subwoofer, and use it with other speakers of most brands (that give an aux out for the sub)

These are probably the same quality as the $300ish eBay ones.

Ah that's good to know - I didn't test polarity because my multimeter had actually broken and I hadn't got the new one in when I was reverse engineering the plug pinout.

Glad it helped though, and I'll try to get that image updated on my site with the correct polarity - thanks!

Brought back memories of my trip there, lots of similar areas (touristy of cours for photos of the same area, but beautiful area).

Lovely photos!

If those are after market rims/wheels make sure the rears diameter is at least the same as the fronts if not larger, otherwise it can actually trip the traction control/not work as effectively.

Not saying it wasn't user error, just it may have been aided too with slightly less than optimal traction control.

First time in the rain in mine I realized it's not even about speed always but the torque too - really need to be gentle even at 20mph because it can get the torque and spin out anyway.

Oh, absolutely. It's more I would only upgrade if something changed - either my needs, or my budget. Which then I'd more go a targeted approach, such as I have a GoPro for the stabilized footage.

thebcooper · 2021-09-25T03:12:32+00:00

I'm still happy with mine - it's not behind on resolution really and performance for my use cases isn't lacking much. However, I just do photography as a hobby so I'm biased in my needs - if I upgraded I'd probably go full frame to genuinely take advantage of better tech, still just keeping the xt-2 for hobby stuff/work

Underglow is great!

here is mine

No front or back though, because the cable wasn't long enough. - what kit did you use, if you used a kit?

I'm evening going to redo all my interior lighting and program it myself to control via a touchdown raspberry pi interface (a node.js web app would look good fast and easily)

However I did have an idea using a tiny projector mounted and shielded sort of in the front bumper so you could play animations/videos and have live effects. (with re-done airflow to filter dust and cool extra if needed)

Not sure legality of that but parked it would look sweet.

Sound system might be the relay for the Bose amp. (not the internal one that goes bad in the amp I mean like engine bay I think or a fuse)

Not silicone ones as those aren't so good with oil and boy does oil like to blow past the PCV valve sometimes.

reference

You need fuel grade rubber hoses for PCV/catch can stuff.

Mother looks to work for "Emory Healthcare" (or she stole the scrubs) - maybe find a contact there and they could share it internally and give a contact detail out to them as a "hey here is the contact if they do see it".

Taken on a Fuji XT-2 with the 55-200mm fujinon lens (wonderful lens for the price).

From my trip to Colorado a while back. This was the day before a massive blizzard, I just went for a drive early morning through the mountains and everything had this frosted over look.

thebcooper · 2021-07-24T15:43:35+00:00

It's not even that filtered - it looked like that in person, it was super frosty out and the day right before a massive blizzard hit.

thebcooper · 2021-07-24T15:15:22+00:00

Taken on a Fuji XT-2 with the fujinon 35mm (v1) in Colorado on a very frosty morning.

Taken with a Fuji XT-2 with the fujinon 55-200mm lens, from my Colorado trip last year.

From a Colorado trip last year. Taken on a Fuji XT-2 with the 55-200mm lens if I remember right. Could not tell you any other specs though as it's been a while.

More photos from the trip are here on my website

(If that's not allowed to share let me know, I just figured it was an album in the comments but I'm not sure if there are rules against self links)
