Sub kicking out full volume bass for no reason

Hi. My sub is driving me nuts. It (apparently randomly) goes to full volume, then will stay on for a random amount of time. It happens regardless of what is being played, what RCA leads are being used, or what input (left, right, or both). Moving the lead (at either the sub or amp end) *sometimes* makes the bass stop.
It's now doing it 30% of the time and is un-useable as a result. Someone in a hifi shop recommended taking unscrewing the back & blowing the connections with an aerosol blower which I did best I can, but the inside of the RCA's are mainly covered with plastic so I'm not sure that it would've done any good anyway.
Any help is much appreciated!

Re: sub kicking out full volume bass for no reason

It's you power from the battery/alternator, it's not supplying enough power to kick it on, if you turn the volume down you'll notice that it'll stay on. You may need to re adjust the settings on your amp or get a bigger alternator, maybe even install a second battery.

I have a JBL venue sub10 subwoofer. I noticed a couple days ago the bass level seemed very high (speech had alot of bass) I tried to turn the volume level down on the back of the unit as usual and it had...

Hi well i would think that perhaps a capacitor in a cross-over network may have failed? What top do is open up the speakers and locate the capacitor, and inductor, cross-over network, that's the part that splits the frequencies to each speaker, hi, mid, bass, and simply replace the capacitor "On Spec" as it were, this or simply replace the entire cross-over network? this may help. It's worth a shot anyway? It also may simply be a bad speaker? again replace "on spec".I don't think from what you describe that you have "Overlooked" anything at all, it's just bad luck.
"on spec' simply means to replace without thinking about it....

I'm about to hook up my KLH to an Onkyo Receiver with Audyssey sound features. 2 questions: it asks me to set my sub to 75 DB. Since my volume dial goes 0-10, which number maps to 75 DB? Also, what...

I think it wants you to raise the volume high enough on the sub so IT can hear at least 75dB. It can always adjust the sub downward if necessary. Max it out at the sub and let Audyssey deal with the adjustment.

Your crossover frequency selection would be a piont below which you want the sub to activate. It depends on the bass capabilities of your other speakers. You want some overlap so there's no droop in the crossover region where your main speakers roll off.

What volume level should I set the sub at please. I have a Marantz 7005 av amp and when using Audyssey to set up, the slam from the sub is miniscule. I normally set it a 50% volume when setting up,can...

It might be easier to "skip" the subwoofer meausrement step in Audessy and tune it by ear instead. Refer to page 52 in the manual, step 6/7.

I use familiar music and test tones when I tune my sub to the mains. Generally, I set the preamp trim to -10db, the crossover as appropriate (80 or below), and then bring up the level knob on the sub to taste. Confirm phase alignment, if possible, by having someone flip the phase (if available) so the response is strongest at the main listening position.

Keep it a little "lean" at first, and over the next several hours or days, bring the preamp level up one db at a time. It takes several days of tweaking to arrive at a level that I find appropriate. Once there, I try to ignore programs with bloated bass - remember, not all recordings are created equal.

Should you fond yourself bringing the preamp level to 0 or above, kick the sub amp level knob up a couple of clicks, and back off the preamp level. It's safer to have the amp do the work, than driving too hot of a signal at the preamp level and clipping it.

Mission m-cube sub fuse keeps blowing

If you have replaced with the correct rating and the fuse blows off then you will need to check for higher current drain in the sub woofer or the network. After replacing the fuse load up the subwoofer slowly, reduce the bass and as you increase check at the point the fuse blows off. Now we need to analyse if the rating of the amplifier you are using is rated for the subwoofer. If your subwoofer has a higher rating you can increase the rating by about 25% and check again. Some amplifiers give a very higher voltage on full bass which could result in such a condition. Moderate this and check again. If the fuse stays Ok you can continue with this new rating.Otherwise the output of the amp at higher volume needs a confirmation. Hope this helps. Good day

I have a wharfedale svp15 passive loudspeaker. The subwoofer has started crackling and popping at low volumes and has no deep bass. At high volumes it sounds great as usual and can't tell if the crackling...

Information I find online says it an Active Subwoofer, so that introduces its own amp as a possible source of the symptom. If there is another version of this model that's passive, all the more reason to believe the amp is the problem because passive speakers don't spontaneously emit sounds.

If there was a physical reason for the crackling I would think more power would make it worse or blow it up.

A poor sub signal cable connection might explain low current anomalies if random noises are entering the signal path.

Make sure the signal, speaker and power cables are not aligned parallel and close to each other.

Subwoofer will not product sound. (ignore product)

Please verify that we're talking about a JBL PSW-D110 here. I'm making no assumptions.

Are you running the Ipod into its L & R RCA jacks as prescribed?

Have you tried it with something besides the Ipod? A sub isn't supposed to reproduce a full range signal. Come to think of it, is the Ipod even outputting anything within the sub's operational range? I don't expect a lot of real bass comes out of one.

Perhaps you could try adjusting the Low Pass up to 180 to see if anything anywhere near the 'real' bass region is present.

Bottom line: There's not a lot of need for a sub (and no other speakers) running off of any music sound source. You wouldn't hear anything above 180hz.

I have a velodyne va 907 8inch subwoofer it has a little volume going through it even though the volume is cut up could there be a blown fuse or some other known problems

It could be anything from a blown fuse to a defective coil in the driver. This is strange because velodyne subs are amazing!! I would suggest to wiggle the volume know a little, if that does not work then look for an external fuse on the back of the amp. if you cannot find one then things become even more compliicated! try these things and let me know if it works for you!
Good Luck

Powered Subwoofer hits hard even on dialogue.

This sub doesn't have a gate (keep the sub from engaging when the source level is low) so it'll "hit" for any input signal. What it does have is an adjustable frequency low-pass filter. If it's kicking in for sounds that don't need big bass reinforcement, try turning the filter to a lower number. The sub will then only kick in for really deep sounds.

Subwoofer "thumping" w. no audio feed

You need to check your ground connection. If there is a bad ground there will be feedback to the amp and it will just sit there and loop back with the Thump, Thump, Thump sound. I had to wire my amp's ground all the way back to the negative battery terminal. It was a pain but I have never had a problem since :)
