Bose Speaker Problem

I have a premium coupe with Bose sound system as usual. Lately when going around corners the left speakers are dropping out. Now over some bumps the sound goes in and out. At first I thought it was just a loose speaker wire in the left hand door, but I have since realised the Left rear side speaker is doing the same thing, which I am guessing may have something to do with where the speaker wire plugs into the back of the stereo itself.

Just wondering if anyone has any suggestions before I start pulling the dashboard to bits?

two things there. the lock is a different probelm and a BITCH to change. about $300 for a new one ex japan.

the audio issue. look at the amplifer in the rear left corner of the boot. pull that out and down then look for dry joints. the radio does this as well but I have yet to see it.

Thanks for that Chris. I'll have a look at that. Now what is a "dry" joint?

If my year 10 electronics serves me correctly I believe it is something to do with fouled solder/contact points on the circuit board, either from wear and tear or from the factory

or components that have worked loose due to vibration. considering how that amplifier is mounted I would point the problem there.

Dry joint, you need to re-heat the solder up and make sure it has continuity all the way through the joint.

If you are a bit unsure any good electrical component repair shop could do it fairly easily... or Chris I would think.

no probs. I'm between cars now (have another sedan due inthe morn) I'll take one of these amps out and take a few snaps of it for you.

if you do head down to see me - ring first.I'm not always here.

Yeah thanks.

I had a look at it this arvo, sure is a lot of wires going into the amp. Pulled out the plugs and had a look around, couldn't see anything obvious, but as a result of pulling it apart, I think the speakers down the left hand side are now sounding very ordinary (very little grunt) compared to the right hand side.

If I may make a suggestion before you rip the car apart looking for amps and shit, test something first.

When you're getting the problem while listening to a CD, flick over to the radio and see if it happens there (or any other audio source aside from the CD player if you have one). I get the feeling the problem is isolated to the CD player.

The 350Z Bose stereos have a known issue (with TSB I'm pretty sure, although I don't have it to hand) where the speakers intermittently drop out while playing CDs. It doesn't happen with the tape deck or tuner (or aux input for those cagey enough to figure out there was one), and it feels like a loose connection since hard accelerating/braking can start/stop the problem. US guys have complained about it, as have a few Australians I know. Since the Z and V share so many components, it could be a common theme.

Nissan Aus didn't even bother fixing it when 2 of my mates had the issue with their Z's. The head unit was replaced. Mine did it just after warranty expired. At first it was the passenger side (both front and rear). Then the driver's side occasionally. Then both. Then back to passenger side. I ended up using a FM tuner or tape to line-in converter with my iPod. I replaced it with a double DIN, and kept the amps and speakers stock, and haven't had issues since.

I think that's the exact reason!! When I play CD's like I mentioned above, the left side starts to cut out. Hard braking/accelerating does help the problem. I have tried to switch between the CD player and Radio and have found that it does not happen when I have the radio on. Hopefully installing a Dvd player with mp3 will work? Since it will be using the Aux setting? How else would you fix it ?

I dropkicked the Bose CD player into the bin, and installed an Alpine IVA-W202E.

Using the aux input should be OK, as the other two sources on my head unit (radio, tape) worked fine and I used interfaces to get my iPod to work.

Could this mean a 'Class Action' against B%SE?

Could B%SE prefer to compensate you all if you advertised in the media that...

a whole raft of people (SAUers undercover) were going to be present at a particular destination (after halfway thru a SAU Cruise) to...

SHOOT DEFECTIVE B%SE CAR AUDIO EQUIPMENT WITH A SHOTGUN !!!!!!!!

Wouldn't they prefer to pay you guys out than to LET THE SHOTGUN GO OFF!!!!! AND THE PUBLICITY THAT WOULD GET!!!!!

      gauge needle removal

      By GTSBoy · Posted

      Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.

      R-chassis INNER tie rod torque spec?

      By GTSBoy · Posted

      Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task

      Don't be ridiculous. "2-3 ugga duggas or one Oof. You have to use Oof on tie rods because you can't get an ugga dugga on there." Is not helping the guy at all.
