how big of a screen does the dd kit fit, 6 inchs?

If this helps before I cracked open my dash to see how the previous owner installed the Pioneer HU I figured it was bypassed. They used the standard wiring adapter without RCAs but they still integrated with the factory Bose unit. You can wire to your choosing. I assumed since they used the standard non Bose adapter my Bose amp was bypassed but it isn't. I unplug the amp no sound comes out. It's best to just bypass the amp from the DIY. Unplug the connector from the amp and solder the input/output wires together. Remove the amp and have it powered on its own. Sound quality has to be better that way. Or run your own speaker wiring from HU or aftermarket amp wires to speakers using RCAs.

People make some of the stuff harder than it is. Ive dealt with much worse before with cars that had 3-4 different factory amps.

It fits double din radios. They come in all sizes of screen, but DOUBLE DIN is the size that fits.

Thanks Makes alot of sense man haha Any idea on what the cheapest jdm or metra kit is? Would like to spend 200-250 max on jdm

JDM typically go for $300 lightly used, Metra can be had for $150 new if you get a decent deal. $200 for JDM is a pretty rare find, but may be possible on eBay or the marketplace here.

What are these 2 connectors too?
Found this when I was inside the dash where the CD player is. All speakers work.

Why should i choose the Metra axxes aswc-1 over the Maestro SW for new pioneer units that are made for the Maestro ? I just got a new Pioneer 4200NEX and Maestro SW . Do you have a wiring diagram for the SW? Im thinking it should be easier as its programmed by the user on a computer before being installed in the car .

They're functionally identical and the ASWC-1 is about $15 less, so there's zero reason to go with the Maestro, and no reason to complicate the shopping list with adding unnecessary options.

Wiring diagram is in the first post.

The ASWC can be programmed via phone (USB-OTG cable) or computer as well.

Thanks good to know they are the same . I got the Maestro for 15 shipped so i actually paid less then the aswc . programming by phone is nice though.

I tried searching but couldn't find anything. I have an 06 G35 with Bose and have my headunit connected with the pac-roem-nis2. The only thing that doesn't work is the dimming functionality on the headunit when the car's headlights are turned on.

I saw that the first post says 06+ do not send the dimming signal anymore. Is there another spot that I can tap into to get dimming to work on my headunit?

I've had trouble in the past with dimmers. Unless it really bothers you I wouldn't worry about it.

The dimmer wire going to the temp/compass display can be tapped as well.

Hey Wrathernaut, Long time member here that can't seem to find my login info, but i need some advice urgently.

Im installing a 4100-NEX into my 2003.5 G sedan that previously had a AVIC-D1 installed. I am wiring up the pioneer harness to the 70-7550. I am powering all speakers including subs by JL amps in the rear.

Do I skip wiring the green, purple, white and gray pairs? If I already did wire them up already, shall I disconnect them and tape them up? Or will it even matter?
Also, my Metra 70-7550 does NOT have its own black wire like suggested by your chart... is that a problem?



Also, I wiring the Axxis unit up for steering wheel controls.

Do I tap into the pioneers red wire on the pioneer power harness? OR is it ok to connect all 4: the red from pioneer harness, the red from metra 70-7550, the blue from metra 70-7550, and finally the Axxiss's red wire all together in one connection?

Also, the chart shows the axxis units black wire should be connected to the m39 yellow and grounded... Does that mean I tap m39 wire to both the axxis units black wire AND another wire that goes to ground?


SO, From what I understand, The Pioneer's blue white signal cable should run first to the blue wire from the microbypass and an added third wire that i then connect to both the the blue/white of the metra 70-7550 and the blue/white leading to my rear amps...?

Last question: Will I need a line driver to up the voltages from the pioneer? IS there any signal loss from low output voltages? IF so, is a line driver the appropriate solution? If so, does it need to be as close to the pioneer's output connections as possible, or may i mount in in the rear trunk near the amps? Will it even matter?

If you're running your own RCAs to the amps, then yes, you have no need for the green/purple/white/gray wires. Tape them up so they're not in the way.

Not a problem, you just ground everything together to the chassis.

Yes, all the red wires and blue (antenna amp power) go together, as do the black wires with the yellow wire (reference ground) from the M39.



You don't need a bypass for the NEX4100. There's one built into the unit, check youtube. Just run the blue/white to the remote power signal wire on the amps.

No, you don't need a line driver.

I was gonna chime in but wrathernaut already replied and covered everything. At first the G's wiring seemed complicated when looking at a schematic but I think you were second guessing yourself. My car had some minor tweaking to it prior to my ownership a few months back. I ripped everything apart and tracked wires to see what was bypassed or used and what wasn't. From your in depth question you already knew your answers before wrathernaut confirmed. I look at wiring now with a schematic and think to myself how do I wanna wire it and that usually works given a person has audio knowledge which you clearly do.

What all else are you installing or did I miss it. Just the headunit, curious on reviews. I'm wanting to a newer pioneer just haven't decided on which of the 20 different models made the last year
