Some Guidance Appreciated

Supermoto25

2012 Nismo
This is my set up guys:

INE W927HD
KTP 445A
Metra Harness
Metra Anthena
Metra Axxes (how difficult is it to get the wheel controls working)
Metra Dash Kit (Read somewhere that is not needed? Is this true?)

Something else needed?

No speakers for now. Possibly later on. Thinking about the db6501 but not sure may be some alpine that won't need spacers if available. I just hate the idea of running cables right now (u guys tell me about gd speakers according my set up)
Would the KTP amp hurt/damage the factory speakers or anything along the road due to overpower?
Also do i need that microbypass? (What is this for?)

Thanks for your time and help guys.

My bad i wrote set up but is what I'm about to install. Thanks

I had the DB6501s in my last Z and they were great. One thing I appreciated was that the tweeters were not as harsh as some other speakers I've owned (but still good highs).

You're getting a heck if a nice HU. I'd get the micro bypass for sure; not to drive down the road watching movies, but just to have many of the basic functions available whenever you need them.

Thanks man. Yeah Ive always run with Alpine. U cant go wrong. Im leaning towards the Polks but still considering the Alpine speakers if theres any that fit without spacers. Just ordered the bypass.

Should hold installing the amp until i get the speakers?

Supermoto25

I believe u had the head unit camera working together with rearview mirror right? Did u remeber where to tap to get it to work simultaneously in the HU? Or did somebody have a DIY? Thanks guys

I used an RCA splitter.

Have you installed this setup yet? I'm looking into buying a new HU soon and am considering the Alpine INE-W927HD. I've been looking into the Kenwood DNX890HD as well but it sounds a bit buggy. Did you consider any alternatives?

I am doing the polk's DB6501 in my Z, I will let you know how it turns out. I am saving the rest of my money for mods.

As for the HU and it's fitment, you don't need the harness. The side mount cage rails will mount straight up to the DDIN units. I have test fit 3 diff HU's just recently as in 4 days ago. I tested an Alpine DDIN unit, and Kenwood Excelon and just finally settled on the Pioneer AVIC instead. All 3 fit with no issues. And many installer shops will tell you it doens't fit flush blah blah blah. BS! I found that they all looked great.

Dash kit is a preference if your anal about gaps on pioneers. Other than that you do not need one. Some think they are cleaner than the stock piece for some units as well.

I installed the HU and here are my problems I read the thread n try a few things but

1 AC thermostat control illumination not coming up
2 hazards button and Synchro Rev not illuminating
3 Dimmer Controls by the cluster bezel not working to adjust the illumination neither they get illuminated
4 steering wheel controls not illuminating
5 door panel light does not comes up (ignore this I found that is a damn reflector not a bulb in it lol)
6 traction control not illuminating
7 after closing the door n locking it with the door button the car does not make the beeping sound anymore (tried holding lock n unlock buttons simultaneously in the remote n no bueno

I'm thinking that most of the illumination problem has to do with pin 8 (white) in the oem harness that needs to be grounded like 15 but not sure. I checked the fuses in the kick panel/under steering n in the battery n everything seem fine. I look at the fuse box behind the battery by removing the cover but did not inspect them cause from what I could read without moving the battery there nothing with illumination related. Is there a Fuse replacement problem if so where please? Or it gets solved grounding the 8 pin? Also I notice that when I switch the ignition button/ start button to Accesories the check engine gives me a code of 5 blinks. Anyone knows what is the car telling me? Is this related to the illumination problem? Help is appreciated thanks guys

I installed my Alpine head unit this weekend and the only problem I encountered was a bad Metra wire harness from Amazon. I had to reconfigure some pins to make it work. Not sure what's going on with yours but I'd get an OBDII reader to find out what the warning is for. I'd say it's a fuse but something might be shorted.

It's not a bad harness buddy. Do me a favor and contact metra about your problem.

Caution with 2013 models and install

If the product isn't compatible with what it's labeled for then it's bad Companies like Metra should be doing their homework and comparing their products with the latest wiring diagrams from auto manufacturers. They likely did that but assumed the risk of returns or exchanges in lieu of the cost of a recall.
