I am having some subwoofer problems
Basically, my sub that I have in my van is making this weird noise. It's kind of like a high-pitched whistle. The noise doesn't affect the music quality, it just worries me that something is wrong. When inspecting the sub, I found a rather small hole in the cone. I don't really know how else to explain it.
I think it's one of the following:
- the hole in the cone
- there aren't any ports to let out air
- my friend suggested that because I have a smaller alternator, it's not getting enough power - which I find hard to believe because I don't think that the alternator has much to do with the amp giving the sub power
Some last info that might be important:
- It kind of helped my other friend understand, so here's an attempt at a diagram:
- I have a 120w 2/1 channel amp
I'm sorry if this is hard to understand, but I'm new to dealing with speakers and this is all very confusing. But I did my best, and if you need any additional information just tell me and I'll try to get it. Thanks in advance!

Sorry, but I'm having some errors with uploading my diagram. So please help me the best you can. And I'd be happy to get any additional needed information.
How big is the hole, if it's like the size of a pencil lead (1/16"), then I'd get some super glue and a little piece of cereal box cardboard and patch it. if it's bigger than 1/4" then I'd probably get a new sub.
That's only a problem if you were trying to build a ported box.- there aren't any ports to let out air
its not the alternator, if i was... you would be driving and lost all the battery power by now, most likely it its the hole
and like furball said, it isnt the air ventilation

That's barely english. Does the noise go up and down with your engine speed?its not the alternator, if i was... you would be driving and lost all the battery power by now
Yeah, the hole is the size of a pencil lead. So super glue and a piece of cereal box? Cool, I'll fix that tonight and see if it makes any difference.
Umm...no. The only time the sound goes away, is when I hit a bump. But then it come right back seconds later.
Sounds like a grounding issue on your RCA. Maybe a lose RCA connection? Maybe the whole RCA jack is lose on either end? Also, some amps don't like to be mounted directly on metal. Just check to see if its touching metal anywhere.
Turn your system on and listen as you wiggle the RCA wiring around to see if you can get it to go away.
System always under construction
My amp is sitting on the carpet underneath the passenger seat. The amp itself isn't touching any metal at all. Should I check to make sure my ground wire is properly placed? If so, where is a good place to have it connected to?
I think I've said this before, but I'm new to speakers, amps, and all that. I've never done anything like this before so I'm just little slow with this.
Recheck your ground. Make sure there is no paint in the way. Did you ground the the seat bolt?
In the back of my sub box where I plug in the wires there was a small hole that did just the thing you are talking about. I just used a small bolt to plug it up and it stopped.
To the world you may be one person. But to one person you may be the world.
Can you walk me through the process please?Originally Posted by Yacob

Should I ground it to the seat bolt? Is that a good spot then? Oh and my friend just corrected me, it's not the cone that has a hole in it, it would be the little bubble thing in the center of the speaker. I'm planning on going down to my local pawn shop and looking for a new sub if I can't get this one working properly, any suggestions for what I have? What I have is a 120W 2/1 channel Amp (an older Clarion).
