Awesome, that'll make getting some extra thump a lot cheaper and easier. Still gonna have to change out the rest, but later, when I can afford it Thanks for the fast response!

Everything is working well, but I had a couple of questions. Thanks in advance for your answers.

1) I have a black ground wire coming out of HU, and a black wire and another black/white wire coming out of the harness. The Crutchfield guy told me to connect these together, which I did. Everything works fine, but I'm wondering if I need to connect these to the chassis. I understand from this thread that the Bose HU was grounded through its metal case. I imagine my new HU (Clarion CZ401) also has a grounded metal case, which I think would mean that my system is sufficiently grounded, despite not having a ground wire connected to the chassis. Am I right?

2) I have determined that the amp on my right rear speaker is dead. The speaker is still good, I believe. Would it be possible or advisable to a) bypass the Scosche amp interface (I wish I had seen this forum earlier and had bought the Metra one, but the Scosche seems to be working OK) and b) bypass the amp on the back of my rear right speaker, so that essentially the HU amp will be powering the speaker. Would that work or is the impedance wrong, or something else? If I swapped out that speaker for a run-of-the-mill aftermarket speaker, would this work?

Thanks!

Hey all, I need some help or advice on my 2006 Maxima with the Bose system no Navigation. All of a sudden I have no sound coming out of my speaker. I went thru all the fuse in the car and all is good. I mean, CD/ Radio/Cassette, Screen, Bluetooth, etc is working, but just no sound is coming out. At first I thought the Bose amp took a dump, but when I it tested on my friend maxima, its was working in his car. But when I test hissed Bose amp in my car, it didn't work same result as my stock amp. So Im thinking it may be the factory Bose headunit. But I don't want to jump the gun and go buyme a $400 double din

It's either the head unit or the speaker.

Swap in another speaker. If it's the same problem, it's your head unit. Bose units are common for having channels go out.

I assume it might be one of that problem, just wanted to get someone else opinion. Thanx bro!

I have coming in; the Metra A33 kit, a double-din HU, 4 6.5's (6" 'sub' is here already), and soon a multi-ch amp.

Don't I still need some sort of adapter for the HU?

djfrestyl

iTrader: (89)

Yes, a standard Nissan wire harness....and an antenna adapter.

hey, all. got an aftermarket hu for our i30 (97) that came with a nissan based harness (7550 w/o rca cables). the hu works, but there is no sound... can i re-wire it for the infiniti w/o buying the 7551 harness? (nothing local, and online will take 3-4 days at least). can i just buy some rca cables and wire them in?

11 and 12 on my small harness are just dangling in the air right now.

i'm also missing the #9 connector, it's just empty.

99zx2

iTrader: (3)

so i've wired the rcas and once plugged in i only get front speakers and the sound is weird - it's quite and there is popping in the speakers when you mess with the hu's settings.
once i unplug them - the sound is great. i'm sure i've wired the rcas correctly. haven't soldered the connections yet though.

i think the part i'm missing is the amp wire. if i were to use the bose amps, where does that wire go? since we're bypassing the hu's amp wire. i've grounded both front and back shield wires as well. any help is appreciated.



the hu i'm using: http://www.crutchfield.com/S-nI9O7HQ...ml#details-tab

says the preamp voltage is 2.2v. i've read earlier in this thread that you need the 7551 metra only if the preamps are greater than 4v?

edit: i guess, i'm an idiot lol i "forgot" that the amp wire that is coming from the hu is for a dedicated amp, in our case = bose. so, should i keep using the existing harness w/o rcas or buy a loc, since 2.2v isn't adequate?

Here's a write-up on how to fix the speaker cutting out, by another member.

I'm in the process of pulling out the rear deck. I pulled out the rear seat/back, took all the screws/bolts/brake light/etc, but I think the rear deck is still held in by the 2 pieces of trim that are to each side of the rear deck.

Anyone have experience taking this off? I'm afraid of breaking something ><

99zx2

iTrader: (3)

installed everything today (7550 w/o rcas). sounds good, except for the interference type noise coming from all speakers when nothing is playing. it gets louder when the volume increases also. noise sounds like a fm radio without any signal. i have not installed the antenna adapter yet. also, should the power antenna wire be wired up with the amp on wire?
thank you, guys!

djfrestyl

iTrader: (89)

C-pillars do have to be removed. Just pull starting at the top. They're clips like any other clip.

99zx2

iTrader: (3)

just a quick follow-up. the noise, once the car is started (but no music is playing) does change with the rpm, but can't be heard once the music is playing. i've read up a few thing online and believe i need to re-do the ground location. right now it's bolted to one the studs that's holding the bose amp, i believe. right below the stereo.

should i still keep them grounded? they are grounded at the same location as the hu's ground wire. should i separate the grounding points for all 3 of them?

appreciate any input.

djfrestyl

iTrader: (89)

Yes, you should always use common grounds.

I think the noise is being introduced through the RCA's. Did you use a shielded set?

99zx2

iTrader: (3)

gotcha, going to keep them together then.

i'm not using rca's since the stereo already came with the 7550 kit, i believe. the po used it without any problems. i've tried wiring the rcas into the speaker wires, then hooking everything up like a 7551 model, but the sound was very low and there was popping everywhere. i don't think this stereo has enough juice (only 2.2v). it sounds goo enough, but if there is any danger to the stereo/speakers running it like that, let me know.

should i also wire the power antenna to the amp-on wire?

thanks, man!

edit: just remembered that i haven't hooked up the antenna yet, since i don't have the adapter for it. could the dangling antenna thing be the cause as well, if it's touching something metallic in the back? i tried to loop it around some wires, but it might have gotten loose and dropped.

djfrestyl

iTrader: (89)

You have Bose? What brand/model deck?

You should power the power antenna to the power antenna wire.
And the remote turn on to the remote turn on wire.

It's my wife's car. 97 Infiniti I30. I've contacted a member about purchasing his bose, but he also happened to have an aftermarket deck, which he said was plug'n'play. here is the hu: http://www.crutchfield.com/S-PIp0VBV...ml#details-tab

i've received everything on Sat. and began the journey lol

According to this diagram, there is no power antenna wire for this hu, but that wire is on the harness, according to the op's diagram.

djfrestyl

iTrader: (89)

You didn't explicitly state the car has Bose, but I'll imply that you do, considering you were trying to purchase a Bose deck from another member.

I don't remember the last time I've seen an aftermarket head unit that doesn't have separate power antenna/remote turn on wires, and I don't see the diagram you're referring to.

But think of it this way. Power antenna is like a remote turn on wire, but only when the radio is in AM/FM mode. If there isn't a power antenna wire, there is no harm to use the remote turn on wire for both the power antenna and the amp, except if you have a motorized up/down antenna, in which case the antenna will always be up, even when not in AM/FM mode.

99zx2

iTrader: (3)

sorry for being vague about the stock hu. thought all i30's had bose.
here's the link to the diagram pic:

taken from this pdf: http://www.pioneerelectronics.com/St...Manual1023.pdf

i don't think her antenna moves up and down any more, so i might just leave that wire disconnected.

aslo, according to this:

i should be getting distortion, but it plays nice. should i bother getting a 7551 harness at all? since my failed rca experiment, i don't think i should, since i would need to purchase a loc in addition to the 7551 harness to make up for the weak 2.2 preamp voltage. any harm running it w/o rcas like this?

thanks a lot for all your help, man!

djfrestyl

iTrader: (89)

Well, guess you're right. No power antenna wire on this deck. Use the remote turn on for both - or just the one since the antenna doesn't work anyway, doesn't really matter.

The quote about levels is dead on, and is the CRUX of this very thread.

7551 won't help, Preout levels are too low. Assuming you do infact have Bose, you need an LOC. If you don't have bose, then straight speaker wire from the head unit into the 7550 is the correct way to do it.

99zx2

iTrader: (3)

I do have bose, but 7550 seems to work good (wasn't my choice, the previous owner had it wired for this headunit). it gets rather loud before i can hear any distortion.

djfrestyl

iTrader: (89)

Then leave it as is. It's not technically proper, but to each their own.

Good luck.

99zx2

iTrader: (3)

don't get me wrong, i'll gladly re-wire it if there are ill-effects associated with the current setup. Appreciate all your help!

99zx2

iTrader: (3)

changing the ground location last night didn't help. still have noise from the speakers. it doesn't increase with rpm anymore though.
i did order the 7551 harness, slc-4 loc, and some other parts needed to get this done. will keep you updated.

XxxSunNyxxX

Yo thanx for the link. Im going to read it now. BTW, I bought me a double din and guess wat???? Same F'ing results...I am so tired of my car audio. WHY ISN'T THERE ANY SOUND COMING OUT OF MY SPEAKERS!!!! Im about to lose it. Everything on the double din works, juss no sound. And now Im gonna go look up at that link.

99zx2

iTrader: (3)

what wiring harness did you use? is your amp turning on?

XxxSunNyxxX

I use the PAC ROEM-NIS2 harness.

99zx2

iTrader: (3)

everything is wired up, and the amp turn-on is connected from the stereo to the harness?

99zx2

iTrader: (3)

got everything wired up last night. 7551 + slc-4 = awesomeness! no more noise and it sounds bad *** with this hu. i think not having the antenna hooked up when i did the 7550 harness was the cause of the noise (since it's bose's ground as well).
thank you, djfrestyl for all your help and patience

p.s. now i need to see why the antenna is not retracting. the power ant wire is hooked up to the amp turn-on right now.

djfrestyl

iTrader: (89)

It's not retracting because the amp turn-on is on all the time. Nothing you can do about this.

If your HU had a separate power antenna wire, then it would only give power to that wire when the radio function is enabled.

Makes sense, right?

99zx2

iTrader: (3)

didn't know the amp turn-on was constantly on. i thought it worked only when the hu was on.

AznRyan

iTrader: (1)

So just pull on the top of the c-pillars? It does have a clip on the bottom (the button-tab in the overlapping-round-holes thing. Sorry I'm not really technical )

AznRyan

iTrader: (1)

Nevermind, after going through a few more searches I found the answer.

Here's a pic, to help anyone else out that wants to remove the c-pillar.

djfrestyl

iTrader: (89)

I should have clarified. You are correct, and that is what I meant.

You're telling me your antenna is up even when the HU is fully turned off? Are you sure you don't have it connected to ACC or +12v?

99zx2

iTrader: (3)

lol the antenna doesn't work, it's down all the time. that's what i've meant by not retracting

djfrestyl

iTrader: (89)

Ah, reverse problem. Have to identify if it's the antenna itself or the wiring. Was it working before? Hook the antenna wire up to constant and see what happens.

99zx2

iTrader: (3)

not sure if it ever worked since we got the car. i don't think it did. i'll do some troubleshooting later. thanks a lot, man!

djfrestyl

iTrader: (89)

Check fuses first, then go from there.

Best of luck!
