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 ?

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!!!!!

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
