I changed out the whole system. Replaced factories with MB Quart all around, Soundstream 800.5 amp, and Premier head unit with satellite.
Info:
Front doors are 6x9's - replaced with 6.5's. Used a speaker adapter
Dash speakers are 2.5's (?) - not sure since I mounted tweeters here- makes for great imaging
Rear doors are 6.5's (stock) with a 1" tweet
You won't want to use factory wiring as it's really thin, and if you have the Bose system you won't be able to anyway due to the amp. I just pulled new wire for mine.
The install was easily the biggest pain in the ass in my install history (admittedly, I'm no pro but have put in many systems over the years) due to having to pull new speaker wire and getting the wiring hidden around all the plastic.
The head unit wasn't so bad. Way worse than the domestics I've worked with in the past because you have to dismount the A/C controls and remount them to a new bezel plate. And everything (I mean everything) is screwed down (unlike the domestics which just pop in and out) But overall, no biggie.
Pulling new wires was a pain in the ass. As best I can tell there is no way around this if you're like me and like audiophile quality sound- I guess you can try to use the factory wiring, but I recall seeing something about having to do some splicing somewhere else, plus you have to figure out how to tie an aftermarket head unit in with the factory amp. Where the factory amp is located, I have no idea. It is not a one piece deal with the head unit, I can tell you that.
But since you're going to just replace speakers, I guess you could just put them in and tie the factory wiring into them. Shouldn't be too bad..not sure how much power the head unit has though. Underpowering speakers is way worse than overpowering them though, so if there's not enough wattage there you could damage your new goods. The factory speaks I pulled were rated for like 20 watts or something ridiculous.
For me (a huge music person) I just couldn't deal with the factory system. Of course, I do this with every vehicle I own. I am doubtful that you could just replace speakers and get that much difference, but it's possible. I'm just thinking the factory head unit/amp will still be underpowered for what I bet you're trying to achieve. You could always get a line output convertor and put in a sub, and then just hook up aftermarket speaks to the factory wiring and leave the head unit. Might be ok.
llajumpvid and others here could probably offer more...
I was running in my old truck a Pioneer Head Unit 50wx4 to 4 Infinity 5x7s. Also had an Audiobahn 10" Sub with a 200watt amp pushing it.
I would like to get close to the sound quality I had before. I still have all the equipment except I left the 5x7s in the doors and traded it in like that.
Is there any way to get the specs on the stock radio?
If you're planning on replacing the head unit, I don't see how you'll get past having to run new wire for the speakers. You could always just hook it all up using the factory wiring though, and see if it works. If not, you know you'll need to run new speaker wire.
There's a lot of good information on this subject on www.titantalk.com Do a search of the forums for "radio install" or "radio". There are pics and links to everything you'll need. Since you don't have the nav screen it's pretty much just like the Titan. One thing that you will need that is different is the bezel. Be sure you get the one for the Armada! Nissan part no. 68260-7S010 Should be around $35-40. The Titan bezel is more expensive for some reason ($60) and doesn't have the cut outs for the rear air controls. This is the piece that you will have to bolt your a/c control panel (4 screws), and emergency blinker button (2 screws) to. There is also a hole for the airbag light, and of course a 2 din hole for where the radio is.
Here's a pic of the bezel cover you'll need:
For the radio install, you can get the Metra 80-7550 kit. I used the standard Nissan wiring adapter as well..should be easy to find. Another note, (not sure if yours will be the same) My Premier unit had a grey trim ring for the outside. It will not fit with the Metra kit- but mainly because of how deep you have to mount the radio. No big deal, but nonetheless. Sorry to not link to the exact parts, but they should be easy to find with the numbers. Feel free to ask if you have any questions.
Here's a pic of my install (had to have a custom bezel cover piece made since I had installed an aluminum dash kit). Would've included the subs/amp, but there's a bunch of crap in the back and I'm too lazy to unload it.
If the stock system has an external amp, it will probobly be located where the bose amp is, which is right in front of your feet. Its mounted on a frame behind the pedals. From what Ive gathered, the head unit either throws line out or rca out to the amp, so hooking up an aftermarket amp sould be easy enough, but running the new speaker wires will be a chore (since i doubt any aftermarket amp is as physically small as the one in the armada). This is all assuming you want to keep the stock amp.. Personally, I'm afraid of upgrading. Might draw too much attention. But damn do I want one.. one of those 2-din Kenwood LCD receiver HUs.. sexy.
Can anyone recommend speakers that will be direct replacements for the front door and dash .... Im going to just swap them out for now. Also, whats positive / negative on factory wiring?
Fronts are 6x9 with a 3" mid tweet in the dash. Rears are 6.5" with 1" tweet. Can't remember the wiring but do a google search and you should be able to find it. Try searching clubtitan or titantalk.
But since you're going to just replace speakers, I guess you could just put them in and tie the factory wiring into them. Shouldn't be too bad..not sure how much power the head unit has though. Underpowering speakers is way worse than overpowering them though, so if there's not enough wattage there you could damage your new goods. The factory speaks I pulled were rated for like 20 watts or something ridiculous.
this is what i've been thinkin' of doing myself. so if i udnerstand you correctly, changing out just the speakers wont' change much?!?
basically, i would like to "upgrade" the sound system.....but w/o changing the head unit and adding a box. so i'm assuming that my options are adding an amp and upgrading the stock speakers.
Well, I finally got my new HU installed. My ride is finally starting to sound decent.
Install list.
Kenwood Excelon ddx8017. (not kenwood fan, but dual zone is feature that I could not pass on, not powered so you must have external amps, great internal crossovers and EQ)
6.5 diamond audio...
Hi All. Just installed a hood protector on my 2017 Armada. The product is called Form Fit made by Focus Auto Design Inc., a Canadian company. Just over $100. No problem shipping to US. Took about an hour to install, seems pretty sturdy. My initial impression is that it's a good quality product.
Found someone locally selling 2018 floor mats in like new condition that were replaced with Weathertechs. Looking at the pictures of 2018 mats (still waiting on pics from the seller) they are a bit different in shape. The front part of the 2018 mats don't seem be as long and they don't have...
but you're the man on the audio side of things.
