speaker help please

[nmlax39]

i have a pioneer dehp5000ub head unit and just installed 2 kicker speakers in the front the onther day. i still have the stock ones in the back. today i was listening to music, didnt have it up real loud. and all 4 speakers stopped working. i got out of my car for a couple hours and everything was working fine.. for about ten minutes then the speakers went off again so the only sound was from my subs. why is it doing this?? help pleasse

Sounds to me like youve got an issue with your preamp(term?)

This is the stock amplifier inside the head unit...might be overheating. This has happened to me before...

see if the unit is getting very hot. This can be caused by all kinds of things. Most units are usually built with a cutoff switch that will kill the amp at a certain temperature.

Im no expert...hope this helps

does it just work itself out or do i have to anything

could be loose connections, could be a bad headunit. ive never heard of this problem before from a headunit, only from an ampifier. i would pull the head unit out and check the connections with a test light and wait until it goes off again. if both powers and ground are good, and you test the speakers and nothings coming out...its a bad headunit.

I ended up having to replace the head unit, eventually it didnt come back on anymore...

What's the temp been like there where you are? It sounds like a bad connection or the amplifier section of your head unit is bad or goes bad intermittently. I'd bet my money on a bad solder connection somewhere in the head unit. changing outside temps from warm to cold or cold to warm (like freezing cold and you turn the heat on in your truck and the HU warms up) can effect a bad connection and make it worse. The sub outputs come off the system at the pre-amp circuit, before the amp section that powers the door speakers so while the amp and door speaker cut out, the sub still plays on...
(PS I AM an expert in electronics

 

[fmaster7]

oh, i actually didnt read that correctly. if it comes back on normally after some time... yes something is overheating.

X2 You beat me to it.

ok i just talked to the audio store by my house and they said one of my speakers could be blown and the hu just doesnt give power to any of them to protect itself i guess, could that be it

I would look at the head unit, If you know someone who can bust it open and repair it Id have them look at it for you.

Otherwise Id say get in the market for a new head unit...

very unlikely unless you have a very expensive audiophile head unit. you could have only 1 speaker hooked up to a HU with 4 spkr outputs and it would play just from the one spk. the amp sections in a pioneer HU is either a single or dual integrated circuit. they are very fault-tolerant and rarely have any thermal protect circuitry unless the manufacturer of the chip embedded it in that IC, betcha pioneer didn't design a circuit to do that on this HU

I would think that the blown speaker would just buzz and pop and the rest of them would keep on truckin' Even if you miswired the speaker you would have known it before now...

 

[nmlax39]

alright. i didnt really believe them either they always try to bullshit me into buying new ****. could a wire have gotten knocked loose cause i was messing with it the other day plugging my usb input in

How did you connect the wires?

Could be a short that only touches when you hit a good bump or something, after a while the HU will start working again (GUILTY: as a rookie I used the twist and tape method *shutter*)

 

[nmlax39]

**** the usb just plugged in an i had a pro install the headunit, i used the twist an tape method on the speakers though, but that wouldnt explain the back ones though cause those are stock still

Right, I was meaning the HU... Good call on the pro install, Thats the only way I do it now. ***WARRANTY***

Well im at the end of mine on this one. If I were you Id look for a new head unit.

Is this the premuim sound with the amp in the back pass wheelwell?? It would be the JBL sound system I believe...with the cd changer and all...thats what I had.

That was an issue on mine as well, thats what I meant by "PRE AMP"

This would have to be touched upon installation, the wires have to be tapped into the harness (soldered preferably)

 

[nmlax39]

im pretty sure it is, could i just amp my speakers, instead of buying a new hu

That HU should have a built in amp (not a strong one) to send the XX Watts per channel to your speakers.

I ended up running wires from the HU to each speaker and bypassing the whole system (A POS I.M.O.)

Everything has worked GREAT ever since, and it should not effect your subs since they arent run through that amp.

If the problem is still there, look for a HU, cuz it could still be an issue in there.

 

[nmlax39]

alright

 

[Mutineer]

alright

Good luck bro, let us know how it goes
