Logic delete? Or add-on?

Need some help guys. I have the logic 7 variant in my e92. I replaced my professional radio with a Sony unit. Connected to an Xtrons MOST adapter. Sounds ok, but I want more output. I have plenty of equipment. Processors, amps, and speakers. Just need to know what harness I need. Messaged techniq but they say they don't have what I need. What I want is to add 2 more amps so I can get a lil bit louder. I want to add the 3sixty.3 but need direction to do so without cutting wires. Searched but didn't find anything concrete. How can I add these 2 amps, or do I need to completely bypass the logic system and run rcas from the stereo to the back and tap into the individual speaker wires. I know this is a dead horse but I need to beat it. 😂😂 Thx.

Technicpnp does make a setup that is for programming the head unit to Hi Fi
But and aftermarket head unit will already have the outputs you need.
RCA preouts.

You have to replace the L7 with your amps and DSP's it has to come out.

His entire kit for this includes a connector that breaks out the speaker outs
from the main connector on the L7 amp I don't know how the power line
is handled on this but you could pull the pin's for that.
Or use it for a turn on signal.
His kit includes RCA's and some kind of hook ups for the analog
out FR, FL, RR, RL at the head unit that are inactive without programming
to the Head Unit (OEM Head unit)

You also might want to read these
there are some side effects to aftermarket head units.

With your aftermarket head unit you would just use the RCA's out from the new Head Unit that and not have to deal with the Most adapter in which case I would order his whole harness.

If you did not pose the question correctly to technic he probably can't give you the
correct answer. Also you did not have an aftermarket head unit when you posed the
original question I believe.
If you asked him I need RCA Cables to run to the trunk for my new head unit
and a Breakout connector for Logic 7 Harness to run my speakers you would get
the correct answer I bet.

https://technicpnp.com/product/logic...-applications/

Look at this thing and understand how it apply's to you.
JUST LOOK AT IT

RCA Cables to run from your new head unit pre out to the Trunk.
For your amps or dsp's

Break out connector to run your speaker outputs into the OEM wire Harness.

A most jumper which you won't need since your new head unit will supply
all the functions the most bus use to supply .

When you take out the Head Unit you will have to program out the devices
on the Most Bus such as the TCU and Mulf 2 hi , Sat module and remove them.
SOS error is the most common irritating one.

Thanks I did look at. That's how I got to ask him. I was very specific, even ask in another reply to the email. But he never got back to me. I did get the sis error, so I bought a loop bypass and will hunt down the error once it gets delivered. I'm thinking maybe do just that and delete the L7 amp. If I do that, tho what issues will I encounter. And if I do it can I just put a loop bypass on that wire at the amp without any break in the fiber optic signal?. If I pull the amp and run everything from the headunit to the 360.3 will i have any other problems?

By using an aftermarket head unit you have essentially removed
the Most Bus period. The head unit is called the gateway module
because it interfaces the Most Bus with the rest of the car.
SOS is useless feature in these cars because it was 2g and is no
longer a supported format by the telco's so BMW discontinued it.
They did something to replace it around 2010 with the Combox
Module but it's not something I miss.

Don't know if putting the Most Jumper in at the Radio kills the SOS
error or not . When my TCU went bad I programmed it out at the INstrument
Cluster and removed the TCU . I would think you would have to do that
but not sure.

So now what your dealing with is an old style situation as far as install
goes.

The issue with having the aftermarket head unit is if you take your car to BMW
they may tell you they can't fix it because it's not in the original configuration
and there software won't work on it.
There are ways around this by using the coding software and just ignoring
the missing Head Unit, Most Bus error.
See coding sub forum .

There software looks at the Vin and reads the VO which is stored in the FRM and
CAS modules and looks for every module that was in the car from the factory
gives and error code if its not there.

Thanks man. Appreciate the info. Smh I thought getting this version would be less headache. Turns out it was way more. I'm not worried about going to BMW. I do my own maintenance and repairs in my garage. It's just this damn MoSt system that sucks.. I just wanna rip everything out and start from scratch.

Sounds that's like what you are doing.
A lot of people don't because it's kind of in the
this is to bad I can live with it range .
And as you have found it's not so straight foward
but a lot of cars make after 2000 are that way now .

No I'm good with that. I have all the coding programs. Insta ncs expert and all. I have no problem pulling this car to shreds just to redo my audio. do it all the time.
I'm going to try this and see if it works.. if not then I will go from there. Maybe this is what I need. Behind all the confusion. Because if it works with the stock radio it should in theory work with the after market stereo that's connected through most adapter. No? It's only 60 bucks, won't break the bank if its not what I need. Plus I can always sell it at a discount if I can't use it.

That link you are pointing at shows nothing.

You could make your own RCA cables it's the speaker connector that you
have to have. The logic 7 speaker connector that is.

https://technicpnp.com/product/logic...-applications/

better off to run rca's from the back of your aftermarket head unit than run a cheap most
converter with a Logic 7 amp . Then run your dsp's and amps which will be much better
than the logic 7 amp.(loose the logic 7 amp in other words.)

Your aftermarket Head Unit has no Most outputs.

No the after market just has this connected.

https://xtrons.com/catalog/product/v.../category/623/

I just bought the Harness from the previous techniq link. I will see what happens when it comes. If not, then I will just pull the OEM amp out and run the toslink from the Sony to the 3sixty.3 then wire up the JL amps.. hopefully I can loop what ever gives me an sos error after I pull the amp.

Most people code out the error in the Kombi module then pull the
TCU for the SOS error.

The following lines in the kombi module need to be coded

TCM_ALIVE_MONITOR -> nicht_activ
TCM_ID_MONITOR -> nicht_activ

You don't need that Most Converter with and aftermarket head unit if you
don't have the L7 amp . RCA's are more practical and you can run the fader
from the head unit .

You started of this whole thread by Saying you had a Sony Head unit.
Sony does not make BMW head units so I thought it was safe to assume
you meant aftermarket head unit. Is this true? Most of what I said is
based on the fact you have an aftermarket head unit that already has
analog pre outs to run amps.

I have the Sony rsx gs9 yeah it's aftermarket. It has pre amp and a fiber optic output. But not compatible with the most fiber optic. If I use the Sony fiber optic it would go directly to the Rockford processor. But still would need to tap into stock speak wires. I'm trying to find a neat way of doing it with out cutting or tapping wires. Looking for plug n play. Even if it means pulling amp.

Yeah the toslink is a good option if your amp and head unit support it.
I almost never hear of that used here as a lot of people code to hi fi
others just buy a cheap Chinese head unit for features not sound and
call it wonderful.

nah buddy.. I'm an audiophile. I love my music loud, but extremely detailed and clean more over. Never been the type to replace a HU with something cheap. The only features I need are DSP, eq, File type options, such as flac, wav lossless. Don't need the big screen, with the bad sound chip, buttons that give out after 3 months, poor support. And terrible fitment. ��

Pretty much as you describe if you really cheap out doesn't mean
you shouldn't try to find the optimum balance between bucks and fidelity.
When you get into the stuff pushed by Absolute Sound magazine I kind
of feel poor.

I can dig it. Lol. I prefer fidelity over everything. But it has to look good as well. Ok. So I looped the TCU. No more SOS. Now all I need is a female connection for the amp, then I can loop that and just use the connection to get pinouts to the factory speaker wiring. Any idea where I can get that? Is that part we discussed a few messages back what I need to connect to the harness before it hits the amp? That way I can wire that extension to my processor then to the amps? Basically I just wanna toss that amp and use the wiring to get to the speakers. I already ran the fiber optic cable from the deck to the Rockford processor. And the processor to the amps. All I need is to tap into the speaker wire to bring it to life. Have an extra loop for the most connection at the head unit. Pulling that eonon most adapter since I won't need it.

Go to a scrap yard maybe and cut one out of a wrecked car.

or

https://www.ebay.com/itm/BMW-E60-E61...YAAOSwDchepKMx

Wrong side connector for that Link I guess.

Right idea, wrong side. I the side as the same as the amp itself. That's why I'm having a hard time finding it. I'm going to just t tap. It's not that deep anyore.
