I've just connected Apline HU through Metra 70-7551.
I connected RCA plugs and red, yellow, black, blue, and orange wires. First, I did not hear any sound at all. Then I realized that I need to connect blue with stripe wire in order to turn on the bose amplifier. Now the HU works. However every time when I change tracks or radio stations there is a loud click. Does anybody have an idea how to fix this?

 

What kind of click? some radio's have them preinstalled

But from what im reading it maybe the install....

 

does walmart sale the Scosche OEA-4?

 

It is kind of popping sound. It is definitely not preinstalled.
I guees it is a grounding issue. I connected the black (ground) wire from the HU to the black wire from 70-7551. Should I connect it directly to some metal surface in the car?

 

Yes, directly to metal.

 

Hi again. OK, I grounded the HU directly to metal but I still have the same pops when changing tracks. Do you have any other suggestions? BTW, there is a black/white wire coming from Metra 70-7551 called "Amp Ground". Should I connect this wire to anything?

 

Amp ground need not be connected to anything, but tape/cap it off to make sure it's not touching anything.

 

Quick question where do the Illumination, Dimmer, and Power Antenna Wires get connected on the Aftermarket HU? (4th)

 

Illumination (+) Gets connected to the Orange/White. Don't worry about the Orange/Black (Negative dimmer), just tape it off. Power antenna goes to power antenna (solid blue -> solid blue)

 

My HU dont have any where for the Illumination, Dimmer, and pwr ant. to go..

 

Did you get a harness?

 

no Im broke and can't order one until next pay, but need some tunes now my CD player on the bose dont work..

 

I guess I will post this here, since it hasn't been posted yet, and the FAQ was unclear.

For good AM/FM reception in 5th gen Maximas, be sure to connect your power antenna leads. The 5th gen as an built in antenna booster, and the power antenna leads connected, you will get very bad reception on your aftermarket HU.

 

This has been posted many many times all over this forum.

 

Anybody have a bose headunit for a 2002 maxima lying around that they wanna sell? Must be fully functioning

 

Post it in the classifieds. This is not the place.

 

Sorry to crap again im having no luck installing my HU I can find the right diagram, all the ones i found dont work....

Im currently not using a convert....

 

After tryim all day I do the radio to turn BUT

I need to know the factory amp turn wire and where to ground the radio because I was testing it on the E-brake plate and its not long to reach....

 

any help would do.......

 

Why the hell didn't you buy a wiring harness?!

 

Im broke and wont have any money until the 18th.....

 

now i just need to know the factory amp turn on, im going to extend the ground to the E-Brake plate.....

 

You're kidding, right? You can't afford $8 at Walmart? Yet you spend hundreds of dollars on a system?

 

Tell me more about why you're grounding something to E-brake? I think you need to have a professional install your system, because the questions you have been asking around here do not make it seem like you can safely install a system.

Shoot me a PM, I will help you out.

 

i cant make a new thread so i will ask my question here. i just got a 95 max with bose. ive got a sony headunit (i know, its sony blah) and i was told @ best buy that metra kit 7550 (the generic nissan kit) will work. will it? ill probably buy scosche's version at walmart for 5 bucks instead of spending 20 at bb. but i need to know if itll work. (i realize i am compromising the sound system doing it this way, but its just a temporary fix)

 

Metra 70-7551. Get it and save yourself the trouble.

 

Metra 70-7551, not 70-7550

 

You slow

 

Tru dat.

 

i got the nissan kit 7551 and i also got the kit that lets you turn down the signal (the schosche # is like oe4 or something). i got it all connected, and i have no signal and no illumination from my h/u which worked fine in my old car. any ideas? i checked all of the wiring, it all seems correct

 

How exactly did you hook it up? Pictures would help. If there's no illumination, you missed a wire somewhere. If there's no signal, then you missed a bunch of wires somewhere.

 

i meant i got the 7550 not the 7551. or at least cc's equivilent. i missed no wires. everything is hooked up the way it should be. im not a total car audio n00b, just when it comes to this bose ****. i think it may be my HU as it used to intermittently shut off but a couple of taps and it would turn back on. damn, and im broke. no tunes in the car

 

So then what exactly is your question?

 

i dunno actually. damn, im gonna try to get a new faceplate cheap on ebay see if it has anything to do with that

 

I would like to replace the BOSE HU on my maxima 2000 with a Pioneer 3900MP. Both the pioneer HU and wiring harness (metra 70-7550 with OEA-4 adapter) have a black ground wire. Should I connect them together or they should be attached to some metal place directly?

Thank you in advance. BTW, does anyone know why I am not allowed to post a new thread?

 

RE Antennas - on aftermarket units, and most commonly Pioneer units, the power antenna lead gets juice *ANY* time the unit is on - on any input. I know some aftermarket HU's don't do that, though - I have a Kenwood, for example, that only puts the antenna up when on AM or FM (not AUX, CD, CD CHG, etc).

 

After reading all of this I'm just going to tear out all the bose stuff. Once you have good quailty sound in your car there is no going back.

 

i'm trying to hook up the metra 7551 now and am having problems. we have everything figured out except for that blue/white stripe "amp turn-on" wire that this guy mentions. what does this hook to??? i cannot find this anywhere.

 

It connects to the turn on lead for your Bose amp.

 

no, the wire i'm talking about is the one on the metra harness. it connects to the car harness, but then where does the free wire on the metra end go. i just read somewhere else that it connects to the thing called "remote" or something similar on the HU. that wire on the HU is in fact blue/white stripe, which is just noticed.
