after spending thousands on my car stereo i was driving around yesturday with it up loud (35/40) and it just turned off.

i though it might have been one of the amps over heating but if that was the case then the sub should of still been going?

im hopings its the fuse at the back of my head deck?

both amps (soundstream 4 channel and pioneer mono) are not turning on at all!??

head deck is turning on playing cd's ect but no sound is comming through anywhere?

i have checked the fuses on the car (electric 1 and 2 and car audio).

any help would be great thanks

edit, i posted it here because the car audio section doesnt get as many readers

do you have a fuse between the amps and the battery? check the fuse on the back of the head unit.

also check that your head unit's face is attached properly and you haven't accidentally muted it... yeah I know, stupid idea, but it could happen.

yeah there is a big ass fuse between the battery and the amps, it is fine

i have a double din pioneer deck so the face doesnt come off

dont spose anyone would know the type of fuse it would take as i cant find the manual for it, and cbf driving around with my dash all over the place trying to buy the friggin thing, from memory its was a red blade fuse smaller then the ones that are in the car fusebox?

Yeah those are the types... I always thought those were for the onboard amplifier though, someone correct me if I am wrong, but I have never actually blown a fuse in the back of a head unit...

Simplify everything, start with step one... Grab some power (with an inline fuse) and a remote wire from the headunit (if you have all external amps, and they won't turn on, it could very well be this) and run new wires to one amp and see if it turns on... If you can't make the amps turn on like that, I would start to worry...

just test stuff one by one...

to be honest i have no idea when it comes to electronics, i have paid alot for all this shit to be installed into my car and im not confident enough to start f**king around with all the goodies, i would probly end up frying myself.

i know basic electronics but nothing too crash hot

i was thinking, because both amps arnt working it would have to be a power problem wouldnt it? grounding or something like that

That or the remote wire... That tells them to turn on and off, if that got shafted and earthed out, it wouldn't be able to tell them to turn on...

Got any friends that can help you out with checking wires and stuff? You just need to run some extra wires to the amps to see if it is a wire problem... That's step one :thumbsup:

was justs kimming thorugh the thread, does your head unit still turn on? get a test light or DMM, check for power at the thick power cable on the amp and the remote wire (little one next to power wire) on the amp, if both have power your amp(s) are gone (if the headunit doesnt turn on, there wont be power on the remote line)

the inline fuses may look alright, but make sure your getting power at the other end, same thing happened to a mate, fuse looked brand new, still wasnt passing power though

edit - there will also be a fuse under the dash somewhere (cant remember for R33's specifically) that supplies power to the headunit, try that one first if the unit isnt turning on

The fuses used are pretty beafy, but when they go, the break can be quite small. I had the fuse go on mine, and by looking at it, you couldn't even tell. If you are getting a DMM you can test the fuse with that. Otherwise, I'd recommend buy a fuse and replace the current one. They are only a few dollars, so if it isn't the problem, it hasn't cost you much, but could save you money in the long run.

    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
    • Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.
    • Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true
