 Subject: Help-speaker cuts out
IP: Logged
Message:
I hope somebody can point me in the right direction here. I put a set of Polk components in the front doors of my Dak last year. They've worked great until recently. A couple of times a day, the right door speakers will get "static-y" and then cut out, always at lower volumes. Turning the volume way up makes them "click" back in, then I can turn the volume back down and all is well for awhile. Does this sound like a head unit problem, crossover, or speaker problem? All else is stock. Thanks for any replies.

I have a similair problem but my speakers do the exact opposite. front left tweaker works at lower volumes not at higher volumes. all connections are good I beleive it has to do with my kenwood headunit and I recently sent it away for service.
its a kenwood if that helps any.

Thanks, but no. I swapped out the head unit and it did the same thing. I took the door panels back off, disconnected and reconnected all the wiring, and the problem disappeared (and the output from the front got louder, too). All I can figure is some kind of corrosion in the connections that rubbed off when I re-did them.
Thanks again.

I know that this is an old post; but i'm running into the same problem. I have a JVC head unit and aftermarket Polk components. At low volumes my passenger door speakers go out, but if i turn them up; they work fine. I am trying to find out if it is a head unit thing or wiring. I am just about to replace my head unit (other reasons) but was going to put it in my brothers truck, i don't want to if it is bad.
Has anyone else had problems with bad factory wiring in the dakota? Once the wires enter the door they go to the crossover and new wiring to hte speakers, so i'm pretty sure that is fine, but somewhere b/w hte head unit and the door i'm worried. Oh, I had the "premium" system and it is still connected thru the factory amp

Does the tweeter on the Polk component set work OK? If so, the problem is definitely in the door somewhere. Try this test Skun. Remove the door panel and remove the Polk speaker from the door, but leave it connected, then try the radio and see if you have the same problem with the speaker out of its mounting location in the door. If it works OK that way, either the speaker terminals or the wire on the back of the speaker for the voice coil are touching metal in the speaker opening somewhere and grounding it out. If that's the case you can use duct tape to insulate around the inside edges of the speaker hole in the door.
How is the speaker mounted? Is it screwed directly to the door or is on a plastic spacer or mounted to the original plastic mounting plate from the original speaker? It is possible the speaker is screwed in too tight causing the voice coil to bind up. That could especially be true if the speaker is screwed directly to the door.
If one of these are not the solution, try having the speaker out of the door and radio on. Move the speaker cone in and out with your fingers. If the speaker begins working then, it has a bad voice coil and must be replaced. If none of these solutions work try swapping the crossover network from the driver's door into the passenger door and if the speakers work OK then you will know the crossover is bad and needs to be replaced or repaired. You could also swap in the midrange from the driver door to the passenger to determine if you have a bad midrange in the passenger door.
This does not sound like a wiring problem with the factory wiring. Check the wires you connected from the crossover network to the midrange and tweeter to be sure they are not pinched, chafed or shorted to metal in the door. From what you have described, it sounds as if the midrange is bad or the crossover network is bad. Check it out and post here, I'll help you with it.

Thanks Jimmy, I'll try some of those suggestions out.
I will have to verify when i test it probably tomorrow or wednesday, but I think that the both the midrange AND tweeter go out. It is not ALL the time, it is just occasionally, some days more than others. Like i said, it only happens at low volumes, and it is fixed by turning up volume or keeping it up (at least 15 out of 50).
I will see if the mouting is causing it to touch somewhere, i have never thought of that; but first i will see if it is just hte midrange, or both.
Thanks for hte reply, I'll let you know!

It could also be the crossover network mounting method. If it gets twisted or bound up, or if it has gotten wet in the door that could also be the problem. Inside a door is not a very good place for a crossover but sometimes you have no choice. You could also run your own speaker wires from the OE amp in the passenger kick panel to the crossover and try to eliminate the factory wiring running thru the door jamb. If everything in the door checks out OK, it wouldn't hurt anything to just connect to the amp out puts for that channel and just tuck a wire in behind the kick panel trim and behind the door panel for just a few days and drive the truck and see whether the speaker exhibits any problems. If it works normally like that it could be the wiring from the amp into the door. With such an intermittent problem, that could help to identify it. What year is your truck? If 2001 or later, the right front speaker outputs from the amp should be light blue with a purple stripe for the positive output and light blue with a black stripe for the right front negative output. I don't remember or have on hand the wire colors for the earlier years. Seems like it was green for positive and brown for negative but you would do better to search for it here or elsewhere on the Internet. Regardless, they should be the same colors as the wires going to the OE midrange speaker location in the door. While you're at it once you find the wires for the door speakers from the amp, you can use a volt-ohm meter to check and see if there is a short to ground between the amp and the door. You could also have an internal problem with the OE amplifier. If so, a good car audio shop could test it to be sure and fix it.
Check it out and see what you find.

I can't believe I'm getting email notifications of responses to a post I made 5 years ago! I haven't even owned the truck for the last 3! How about starting a new thread guys?
Good luck with the problem though.

QCMemphis: I'm sorry, it is just this post was extremely relevant...sorry to hear you sold your dakota.
Jimmy: I feel soo stupid, but thanks to you I found my problem...it was the crossover. When I had installed the wires (actually it was the tweeter, I had screwed down on the wire and the insulation, so sometimes the wire would not be touching the contacts, but most of the time it would; don't know how volume made it better (maybe vibration from the midrange that still worked caused it to stay connected). Anyways; hopefully my problem is solved.
Thanks for you help, sorry it ended up being a dumb mistake!

I had this exact same problem last week. I have an Alpine CDA 9883, had eclipse front coaxials and Infinity rear coaxials, all run off 4 channel Kenwood. Started having a problem with front passenger speaker getting static then cutting out completely, then coming back on when I cranked the volume.
Upgraded to Eclipse front components with separate tweeters at a high end shop, still the same problem. Finally went to Best Buy(YES, there are some competent Best Buy people in this world).
From what this guy said there were some loose wires that weren't needed when another shop swapped my head unit and they just left them hanging there without taping them up. Evidently this caused some sort of interference that gave problems with the wiring to that speaker. They taped the wires up, put it all back together, and the speakers have worked perfectly since then.
I would say, check RCA connections at amplifier and head unit first. Look for loose ones or wires that are severely bent or rubbing against something really sharp or exposed wiring. From there I'd test the amp, and look at possibly putting the head unit in another vehicle or finding some way to test the RCA outputs on it.

Well it turned out to be a bad amp, one of the soddered terminals broke or something like that. KEnwood is goon, a 70 watt per channel MTX Thunder is there in its place. I could say it sucks that I wasted money on components when that wasn't the problem but it's so much better, I still don't regret it.
