Ok I’m not sure where this goes but I have 1992 f250 7.3 idi that I bought with a blown left door speaker but the rest worked and it had an after market headunit. Never had an issue with anything as far as the other three speakers.
I finally getting around to replacing all four speakers (the originals were factory) and now suddenly after about a week or so all my speakers have started going out together, all at once. I’ve pulled the radio and checked the connections and tried like hell to wiggle something loose and make it happen but I cannot actually recreate the problem. It just either randomly happens when there’s no movement of the truck and sometimes it will do it when i hit bumps and sometimes when it’s trying to come back on it’ll crackle and skip but then die again. I have no idea where to go from here.
It’ll work for a week straight or it won’t work at all or it lol work for a day and then quit again
all 4 speakers have separate sets of wires to the radio. If wiring was the issue seems like they wouldn’t all go at once
How did you hookup the OE wiring to the new speakers? If there's a faulty connection the speakers would definitely pop in and out. Also, do all the speakers go out at the same time? You're unclear in your first post.

sorry the would is supposed to be a wouldn’t. So yes they all go out at the same time.
as far as how it’s hooked up. I originally left the what the old owner did with butt connectors and an adapter plug type set up. Then I thought the connections there might be an issue so I had the connections redone but it’s still having the same problem
what is also unclear is IF it is a floating Ground system or a Common Ground system
What model number Head unit, what Amp, what is speaker Impedance ?
I don’t know what you mean by floating versus common ground. All four speakers have a separate ground and positive going to the radio plug. I’m not sure which headunit it is but the issue happened with two separate aftermarket JVC units. I don’t believe there is an amp and I’m also not sure what speaker impedance is.
Since the speakers all go out at the same time I would look at your connections at the head unit. Did you use something like this when you installed your aftermarket stereo?

my truck is a 93.... I have a later model Factory AM/FM CD Cassette installed.....But this is my original wiring diagram.....
Maybe this can help you.... the original wiring is for a Floating Ground ... and since you said JVC then I assume they use a floating Ground also AND IF one of your speaker Negative wires happens to short to Chassis Ground it is possible to Kill all speakers and even damage the Amps that drive the speakers.
not knowing the specific model you have I cannot look deeper into the Electronics to make better sense of what your problem might be.
But Mismatched speakers could be causing an issue too.... surely the head unit came with Instructions.
How was the wiring adapter installed in the truck? The wires coming off of the wiring adapter should be spliced and soldered into the factory wiring harness with heat shrink. Was this done properly?

the speakers are all the same and what amp are you referring too? Sorry but I’ve never had this issue switching out speakers or radios so I’ve never had to dig this deep and I have no idea what most of this is
also it worked just fine with the JVC and the original speakers so why is there an issue now? The speakers plugged right into original wiring with the adaptor plugs. And moving the connections doesn’t recreate the problem so wouldn’t I be able to tell if something came loose?

It wasn’t soldered it was done with butt connectors that you can heat shrink around after you crimp. I understand soldering is better but I’ve done it several times with butt connectors and it’s worked for years.
the Amps That I refer to, are the Final Drive circuit in your Radio since you don't have a separate Power Amp.... (Internal Components Normally Integrated Circuits )
I assume the original Harness is intact and you just have a Pig Tail from the Radio to the original Harness connectors as this would be the Preferred way to install an aftermarket unit.
IF the original harness doesn't have any shorts to Ground... then maybe it is a problem in the OLD radio.
Since you don't know IF the speakers are matched for the radio and you haven't indicated any wattage levels Maybe the new speakers are already blown.
Blown speakers have a habit of fading in and out....(Open Voice Coil) it can re-connect at random.
BTW Butt connectors are as good as a soldered connection Providing they are Crimped with the correct tool.

I don’t see how the new speakers can be blown since they sound amazing when they are working.
and as far as the harness yes the original wiring is all there with a pigtail harness correctly connected. As far as the old radio I’ve switched out to another aftermarket radio and I still have the same issue.
