I'm no expert but from what I understand the architecture is insanely more complex than your everyday off the shelf stereo system. So much so, that beatsonic is the only manufacturer to design a "workaround" harness in all these years.
But I have read a few threads on CL where members have had success with splicing and some other methods Ala Kansas and that best buy installer.
Yes it works.
I have a 93 LS400 and I installed a Pioneer AVT-X2600BT in my dash. One of the things I did extensive research on beforehand was seeing about installing it so as to use the factory sub. My friend who is a sound engineer helped me with the install (I could have done it myself but like the company) and we tackled the whole install in a little less than 4 hours.
The sub harness is the third harness that doesn't plug into the prebuilt easy wiring harnesses you can purchase. It also has some wiring built in for the cell phone if that was an option that you had.
The trick is to grab an old RCA cable and slice it open and separate your negative and positive wires so that you can either solder or do crimp ends on them (we did crimp ends). And then you hook those up to the factory sub wires by just cutting them from the harness. You can also get the crimp t connectors if you prefer to leave the original harness in tact. Now of course this will only give you mono, but it will work marvelously. I have it working perfectly with no problems.
I can't find the diagram for the life of me right now, but if you are looking at the end of the wire harness it is the two left wires top and bottom I believe. I can try and grab some pics when I'm in there next, which should be about a month from now.

The pic in this looks just like what I did. Try that. Even though it is a different model works exactly the same.

to summarize:
- get an RCA cable, and cut one end off
- the cut side, tap into the factory harness as shown in the pic below
- install the RCA side on the "SUB OUT" of the aftermarket HU
am i correct?

This is an awesome thread, gonna try this. Have a GS parts car I can steal the sub from, but how do I know if my car still has the amp? Anyone know where it is? Also, which wires go to which? On the sub out you usually have a red and a black, no? I'm gonna pull my radio this week if I get time, I could use more bass.

This works for my year 93 and 94... but I'm not sure about other years. As msweber97 says, the exact harness in the pic may not be the same. However, if you can get a diagram and if the amp only requires a low level input without any other signal for power, then the method would be the same with the only difference being the wires used to send the signal. The only other variation which may be an interference is that my system is a Pioneer rather than the Nakamichi.
Hope this helps.

yeah that must be the difference then since mine being a nakamichi and yours a pioneer, there are a lot more wires in my harnesses. Hopefully i can find a wiring diagram for the nakamichi system and make it work!

I went with it, but then noticed my original subwoofer cone was torn to shreds. I bought another OEM on Ebay and I couldn't be happier. DVD, bluetooth, HDRadio, SiriusXM, Pandora and plenty of bass for my 49 year old ears.

If you're not the mechanically/electronically/breakfix inclined type just get the Beatsonic and move on. It's expensive as all get out, but not so much when you factor in the subwoofer cost savings.
