Speakers wont work in my truck?

Question

I have a clarion deck and four factory speakers( two 5 1/2s and two 4x6s). When i start my truck the speakers work just fine, but at random times they will just stop working, but my stereo doesn't shut off, just the sound does from the speakers. I went to aspen sound and they said it was a blown speaker, which sounds right because one of my speakers sounds fuzzy and unclear. But i don't get how the speakers will sometimes work for a couple of days without shutting off and then sometimes only a couple of seconds. So i think it would be a bad connection or pinched wire behind the deck. It just doesnt make any sense that it would be a blown speaker if the sound shuts off when i slam the door or hit a speed bump. What do you think?

The tech guys at aspen sound said that one blown speaker can send a signal back to the main unit and cause all speakers to shut off.

Answer 1

A blown speaker can sometimes cause what you're describing, but more commonly it's a pinched or shorted speaker wire. In either case, if there's not enough resistance through the speaker (damaged voice coil) or if the speaker wire is grounded, it can cause the head unit's built-in amplifier to shut down.

In my experience, it's far more common for this to be caused by a shorted speaker wire than a blown speaker.

The easiest way to troubleshoot is using a digital multimeter with an ohmmeter function. Wait for a time when you're not getting any audio, then pull the deck. Inspect all the speaker wiring behind the head unit for pinched or bare spots. If you don't find any, check the resistance between each speaker wire and the chassis ground wire. There should be no connection between ground and any speaker wire; if you find a wire that shows contact with ground, it's the likely culprit.

Truck Speakers

Answer 3

The tech guys at aspen sound are complete idiots. A speaker CANNOT send a signal back to the HU regardless if it's blown or not.

Your problem can happen for many reasons:

Bad solder joint in the HU
Loose harness connection
malfunctioning thermo-coupler

Answer 4

Did someone wire the speakers such that one side of the speaker is grounded to the door frame? That could account for the intermittent behavior.

If so, you can fix it by either running a second wire, or just pull a new PAIR of wires, or get a braided grounding conductor and sheet metal screw it from door to door frame on each door.

Answer 5

sounds such as you have a loose connection. must be the two a floor cord, or known. The motor vehicle would not unavoidably could desire to hit a bump, the two, in case you have a undesirable/intermittent floor, this is going to circulate out while it sounds like it. you could desire to learn all your connections. it must be a pinched cord besides. simplest way is to discover the harness to the radio or deck, the place each and every of the connections are, and with the radio on, jiggle them gently separately, see if any shrink-out happens. if no longer, perhaps slightly harder. then examine your speaker floor connections. in the adventure that your audio equipment are not securely bolted in, they won't have a reliable floor ( no longer purely the wires ). considering you have ability to the deck, does no longer recommend the speaker connections by way of it are stable, the two.

Answer 6

I ran into the same problem recently, I took it to one shop and they tried selling me speakers. Went to another and found that do to improper installation the wires had been crimpted and drilled through going into the head unit. So at whenever the car bounced it would cut out. Most problems occur as a result of bad installation.

Answer 7

check the plug in back of the radio and if it has a wiring harness check that. commons to your problem 1 wiring connection 2 radio - internal amp . One bad speaker or pinched wire would not effect all speakers.

Answer 8

I would think there is just a loose connection somewhere and it will be in tact for a while and i wiggles loose
