Weird Loud Beep Noise From Speakers

hey sau,

Recently ran into some problems with my system. When the headunit is turned on a loud beep noise occurs from my speakers. Have a alpine motorised single din dvd screen headunit. With full soundstream picasso front and rear speakers with a 400w soundstream amplifier. Not too sure if i should have my settings to HPF,LPF or Full for my front and rear speakers. Along with my speaker frequency set to 50 or 20. This noise seemed to be happening a while ago just resoldered some wires and taped them up from the front speakers, and the noise seemed to go away. I press the power button on the headunit and have a look at the amplifier and the blue power light stays on until the loud beep occurs then the protection light comes on. Would this mean it is shorting out somewere?

need some answers desperately as im selling my car shortly

Best regards chris

you could try disconnecting front and rears separately and see which end creates the fault. i can find specs for my old soundstream amp online so have a go and maybe if you find a manual it will say something about making a noise to indicate a short or overtemp etc.

Front and rear speakers should be set to HPF any subs set to LPF

Firstly recheck your work ( some cheap elecy tapes peel off, Wires rubbing on an edge) Sounds like a shorted speaker or maybe a ground loop. If not you should still able to be fault find.

1. Unplug the RCA's to the AMP and then turn back on, does the tone contunue?, does the Protection light come on?

If neither, the problems probably in the RCA's (loosing ground) or maybe the Deck. Check indash wiring and Voltage to the Deck

2. Remove the Speaker wires from the AMP and turn back on, If the Protection light and the tone continue check the voltage at the AMP, otherwise the AMP may be toast

3. Test the Speakers, grab an old 9V ( 3/4 flat ones are best), stick it on each speakers wires in turn, you should get a crackle/pop out of the speaker if its OK

PS. Do you remember which wires you resoldered? (Amp to Speaker?)

Cheers

Bundy

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
