Dash stereo wiring pinout dsp

I'll start by saying I know this topic has been beat to death here. I apologize if I missed another post with the info I need. It's not for lack of trying.
I have a dsp system with nav and cassette. The wiring has been hacked by the previous owner. What I want to do is just remove the system and wire an aftermarket double din in the dash. I'd prefer to use the speaker level inputs for an aftermarket amp to simplify the wiring. The factory speakers will be replaced with coaxials. Can the steering wheel controls be integrated into an aftermarket unit?
I have read many threads about the problems integrating DSP with aftermarket. I am also aware of the problems with removing the OBC, it will be relocated. Please, no suggestions of dynavin or other units.
No disrespect to the sage advice of the forum, I just need the pinouts for the dash unit and wiring leading to the factory amp.

Thanks for the link. I'm in no real rush right now. I have too many irons in the fire as it is. Just wanting to have info when I get ready to tear into the mess that I have. Fortunately, the PO only mangled the wiring for the stereo. All else is intact.

Hi,

Edjack - Cheers for the recommendation !

Joe Tag - By removing all the OEM modules (head unit, DSP amp & speakers) and replacing with good quality aftermarket brand car audio products, the wiring and installation of them becomes substantially easier to do. However, given your car is/has DSP, then it's more involved as all the speaker cable runs go from each speaker location to the back of the car to the DSP amp. You'll not have the speaker wires in the dash area location. The best way would be to choose the head unit you want and run a set of RCA cables from the dash area to the back of the car. Connect those to the amplifier you choose. Via online searches, also searches here on bimmerfest and bimmerforums, you'll find the speaker wire colours for each speaker location and you can use the correct ones to each location. You'll see that some will not need to be used as you'll only need a stereo pair to the front and rears that will carry the amplified 'full range' output signal and you'll use those to 'input' to the crossover unit for the front speaker components you buy. From there, a short pair of cable runs to the tweeter and mid bass driver will be needed. For the rears, it's co-axial speakers you'd need so just turn the gain/bass boost down for those and wire directly. I'll assume you'll get a subwoofer so the speaker cable run I'd say just buy a couple metre's of good speaker cable and hide as required.

Will you be choosing high quality, respected car audio brand equipment ? or are you thinking of low quality Chinese head unit and budget/unbranded equipment ?

Cheers, Dennis!

The plan was to get an android based head unit with a 3.5" mounting depth to avoid the clearance issue with the ducts. Four coaxials in the doors and a 10" sub in the rear armrest. Right now, high end equipment is not in the budget. I just need some type of sound to get me by in the meantime. I have nothing right now and I don't see being able to easily repair the factory setup. I'll upgrade as funds permit.

Hi Joe Tag,

For a very similar price to the unbranded, unreliable chinese head units, why not go for a high quality unit in the shape of the Alpine iLX-W50? this unit comes in at $295 USD delivered to you (assuming you are indeed in the USA!) https://www.sonicelectronix.com/item...-ILX-W650.html - Shallow depth, genuine Apple CarPlay & Android Auto, Parametric EQ all with vastly superior sound quality.

Then, over time as your budget allows, get the equipment to match and you could also have it looking like this in the dash;



I'd strongly advise you not to put 4 co-axials in the doors, instead, put a 2 way set of component speakers in the front, using the oem tweeter location and mid bass driver location. You can get some cheaply made MDF baffles at around $30/40 USD which mean you can remove the oem plastic enclosure and mount the component driver in and they will sound much better than using co-axials in the door.

Spend your money once and get the right grade equipment/products for the application, don't cheap out now and then have to spend money again later !

Cheers, Dennis!

You, sir are a bad influence. lol I fully understand the concept of doing something right the first time. At $300 I just can't do that right now. I'm doing a suspension rebuild on this car, fuel pump whining, need to head that off before it becomes a problem. Doing the back up camera retrofit for the wife's e60, complete remodeling of my daughter's house, Christmas,etc, etc. My pockets are only so deep. I will skimp some on the things for myself so I don't have to on the things for my family. I'll suffer with a mediocre sound system until I can recover from this.

Hey Dennis, does that Alpine unit come with the OEM looking left and right controls? If not, are they functional? I haven't seen this setup before. Looks clean.

Hi Joe,

No the Alpine head unit doesn't come with the fascia/fitting kit you see there !

You need to purchase that separately and I agree with you it is a clean looking solution!

Part of the reason it's clean, is that I invested a good amount of time ensuring it was designed like that

You can read more about it here;

https://forum.bmw5.co.uk/topic/13564...le-din-fascia/

Phase 1 has the buttons for aesthetics, but I've left the design 'open' so they can be functional if desired and an owner can either DIY or give to an electronics specialist to connect the PCB up

Joe Tag - I fully understand on where you are coming from ! just done a full respray on my car, full and in depth mechanical overhaul, added some more mods as well! the house has also had building and remodelling work done too! Resist the temptation to settle for some low quality chinese electronics and hold out/Save up for excellent quality at just a nominal amount of cash more

Cheers, Dennis!
