VERY sore and tired just got done about an hour ago. Will fill in on how to install the MS8 in one of these.
Sounds great does need some tuning however did not have the time tonight.

I agree! For all who do not know, the IS-F belongs to me and it's amazing to have this system install by my good friend Matt (BigAudioFa,) and yes, this build took forever and left us no time to tune. Still a couple of minor issues that need to be worked out and of course, tuning. But overall, sounds a lot better than the ML system and NAV along with every other function in the car still works.

There still is some minor rattle, but I'm collecting data on where exactly the rattles are coming from before I attempt to rip her apart again and dynamat some more.

Other problem areas for me include: sunroof when tilted open, driver side sun visor, gas door, and license plate.

Great job guys... I imagine this was a giant PITA but expect that the final results will be amazing... few questions though... i see you put tweeters in at the midrange location, so what did you do at the original tweeter location (near the mirrors) and also what did you do in regards to the center speaker channel on the dash. How much of what you did is reversible... if you decide to one day trade or sell the car will all this equipment have to go along with it? Subscribed

The rear speakers and center speaker wires had to be cut from the amp conector on the output side of the amp "pics explaining later" The only outputs I grabbed from the stock amp are the fallowing:
Left Front Low White +/ Red Wire -
Left Front Mid/High Brown +/ Pink -
Right Front Low Sky Blue +/ Orange -
Right Front Mid/High Black +/ Green -
These all were ran into the MS8, all other speaker outputs were CUT because they would still produce sound. The alternative would be to disconnect them, however the rear deck and center I did not explore.
NOTE These are the colors at the amp. I did verify each one of them using a volt meter at the other end "door wire" and they were the same color.
In order to setup and run the ms8 without a problem, the factory DSP was disabled through the menu.
2. The stock tweeters were left alone as to keep things looking factory. With some modifications you could easily run a 3 way setup if you prefer. I could of easily created tweeter pods if the customer had preferred. But he wanted them to remain as stock as possible.

System
Just a question/observation
Doesnt the ML amp itself distribute the frequency content to each speaker -- ie. it has internal cross overs built in...so in essence even if you got the output from the ML amp for the front low & mid/high ...if it has crossovers built in wouldnt it still be cutting the low end per say on those speaker outputs and giving the low frequencies just to the rear deck subwoofer?
(which doesnt really pump that much bass - lets all face it)
So arent you feeding your amp whatever the ML amp would originally have been feeding those speakers outputs (that you now have rerouted to your amp)...where is even if summed together feeding your amp, the ML crossover would still not feed the low frequency to those outputs anyways...so you'd still be missing the low end frequency (100Hz and below) at the input to your amp?
as the ML only feeds the real BASS (according to Lexus that isnt too low) to the factory sub...so wouldnt getting your input from the ML amp output be in essence already giving you "pre- crossed over" processed music....so if there is no real lows(bass) in the output of the ML - you wont ever get those real lows that come from the original music --- like you would per say by getting your input directly from the Headunit (radio) before it gets to the ML amp to be processed cause then its all sliced and diced by the ML amp (crossover frequencies) so the bass goes to the sub, the mid bass goes to the door woofers, the mids go to the mid speakers and the highs go to the door tweets.
getting the feed direct from the Headunit in its raw form - wouldnt that give you all frequencies - not processed ? and feed your amp everything so you can then use your amp's crossovers to feed your component speakers and sub ?
just askin -or would the DSP stop that complete cross over process?...or just at certain speeds..
would be nice to get the feed from the HU
any insight is appreciated

So what I am saying is if you/I wanted to add the sub to the input of the MS8 to be summed it probably would not make any difference in what I have observed/heard. I will verify this in closer inspection when we get together again for fine tuning. Right now there is plenty of real bass for the owner to work with.
Sadly you can not tap the pre inputs of the OEM amp because everything including the bluetooth would be lost as that is all done internally inside them amp, you would also lose the control of volume from the head unit if you did this as all those commands are sent to the OEM amp.
