I have a 2007 Safari 25. The stereo includes a sony multi-cd, a subwoofer, dvd player and tv.

Strange noises: low pitched grumble from the subwoofer; a high pitched whine from the stereo that comes and goes,
and a low hum at low volume levels.

Any solutions? I live 6 hours from the dealer.

Heavy metal

Funny your reply should mention Heavy Metal... we have a 23' 2008 Safari SE and I have noticed exactly the same thing. Great audio quality - but that low rumble when listening to qiet music over dinner. I would love to know the fix. Maybe an electronic noise crossover or something?

I suspect converter noise. Do the strange noises occur while boondocking? In other words, do you hear the noises when you are unplugged from shore power?

Good point Tom.

The high pitched whine is from the converter. I have the same problem and I am rying to figure out a way to block it. I am still looking for choke big enough.
THe grumble. check under you couch. See if the drawer is hitting the sub woofer. Mine was and it broke the conector on the front. The factroy will send you a new one if you need it.

Sorry if I'm hijacking this a bit, but I'm pretty much of an idiot when it comes to using my sound system. I've read the manuals, and one thing I haven't found is a TIMER or an ALARM. I'd like to wake up in the morning to music, and a cheap clock radio I already have isn't satisfactory. Lousy reception... inside an aluminum tube...whattdayaexpect.

Do the new ones have any timers built in on radio or CD?

Paula,
No alarm clock in the stereo. The units in the trailer are car audio units.
I have an older Bose Wave radio unit that will let you wake up to noise, radio or CD.

Hi Paula. They are using automotive stereos inside Airstreams and they don't have any feature to wake up the driver. Rumble strip? Okay, that's not a good idea for an alarm clock.

There are some bedside alarms that take a CD. Yes, radio reception inside is pretty poor.

The noise occurs when boondocking, so probably not the converter....

Interesting ideas... I have an ipod which has no heavy metal, unless my kid put some there.

Good idea on the drawer, but it was not touching the subwoofer...

Our subwoofer makes a low grumble (It sounds like a cat purr to me) only when playing a DVD.

thecatsandi · 09-25-2007, 09:08 AM

Do you have an inverter?

campadk · 09-25-2007, 07:34 PM

Same thing happens with our 75th. Subwoofer rumbles, groans and drives my wife battie! Plus the high pitch whine

Electrical hookup, or no hookup the noise is ALWAYS there. Hard to believe Airstream never noticed this issue as others have reported it.

This noise does NOT require the heater or anything else to be on for that matter.

I will record the noise for all to enjoy this weekend

We do have a solution thus far... turn the fantastic fan on to '2'

billtservice · 09-25-2007, 08:00 PM

The Rumble that you here and the whining are coming from the same source. That source is the subwoofer itself. It also is made worse on trailers that have a cooling fan on the back of the refer. That cooling fan creates a noise through the subwoofer. The way to find out, is to unplug the subwoofer completely. Since you cant eliminate the cooling fan, you can eliminate the use of the subwoofer itself.

campadk · 09-25-2007, 10:07 PM

Actually the high pitch whining comes out of the speakers not the subwoofer.

Maybe if we unplug the subwoofer AND the speakers we'll eliminate the problem!

wheel interested · 09-25-2007, 10:22 PM

Save yourself the work just use ear plugs.

Ours makes noise too.

SilverGate · 09-26-2007, 10:02 PM

You might want to adjust the controls on your sub-woofer, such as the one for gain.

You can unhook the sub, and leave it unhooked, and unplugged. Rich Luhr did this with their trailer, for much the same reason. The fan feeds back through all the speakers.
Unless you're listening to Slim Shady, you shouldn't need the sub anyway.

Dave,

You are right...the whining comes out of the speakers...most of the times the ones over the bed are the worst...however, if you unplug your sub-woofer most of the time the whining stops...it worsens on some units when the fan to the refer kicks on...it is something in the sub-woofer itself that causes
the interference with the speakers.

Did you find a solution? I have the same problem while watching DVDs and only at times in the movie when the scene is relatively quiet. The system sounds great the rest of the time.

I don't want to unhook the subwoofer. I just want it to work correctly.
