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!!!!!

    • I just got to work and skimmed through 61508 and 61511. I was surprised the CSA adopted both, but neither are enforced. To recap what I read, it states that in a perfect world, they should be segregated but they acknowledge that this is not industry standard and clearly mention that they allow mixing of safety and non-safety. 61511 also mentions software segregation like AB does in their safety PLC's.   Now if only I could go back to control, let alone safety over comms. In my current line of work, we're only allowed monitoring and basic control over comms. Everything critical must still be hard wired as much as possible. 
    • I've unfortunately never been as they're on the complete other side of the continent and another country that isn't currently letting us in as easily as they use to. I even heard their stop signs over there actually say "Stop" instead of "Arret". If I decided to trek the 48h drive, I wouldn't know when or where to stop haha. Whenever I order parts from UP Garage, I order from Japan as it's cheaper. Same with GKTech... oddly enough, it's cheaper shipped from Australia then it is the US.  UP Garage Japan operates their US leg though, unlike Tomei. If Tomei JPN had the power to close down Tomei USA, I'm sure it would be done in a day. They're two completely separate entities. Tomei JPN messed up somewhere originally agreeing to its creation and got sacked big time. 
    • I asked someone about this and he told me about the Audi 1.8T engine. But I think it would be difficult to swap
    • I don't know that machine specifically, but I'd personally go for something with a little more kick than 130amp. Around up to 180 would be good. At the 6mm range, you're really pushing the machine hard and don't have a long period you can run for with out needing to give it a rest. Lots of MIG machines come with a regulator and hose. A lot will come with a starter roll of wire too, but it isn't too expensive to buy. I'd recommend NOT buying a massive roll too, as you don't want it sitting around FOREVER in the machine between uses and potentially going to shit. For thin sheet metal, get a roll of 0.6mm if you're doing over 3mm and above, switch over to 0.8mm wire. Even by 2mm you'd probably really want to switch. As for gas battle, it's all swap and go style now. You'll pay a bottle deposit, and then X amount to swap for a full one. I think it's like $200 or $300 for a D Size bottle upfront as "deposit", and like $110 to $150 per swap. My D size CO2/argon bottle lasts a fair bit of welding on the MIG. And I run an E size bottle on the TIG. For DIY MIG, stick with a D size bottle. If you really start to get into a LOT of welding and doing it really regularly, then upgrade. If you're like most DIY car guys, one D bottle will last you 2 or 3 years easily. I think I've been on my current bottle about 5 years. It is starting to get low, but I've been smashing it a lot more the last 6 months.
    • SR20s came with cars like the Bluebird and Primera, but the RB20 never came. The ones in Turkey were either brought in specially or from abroad. That's why RBs aren't as common as SRs. And if a part breaks or I need to replace it when doing maintenance, it's harder to find parts for RBs.
