It is mostly a ground hum. You can fix this problem by buying a ground loop isolator. Another problem you may be having is the preamps on your stereo unit are bad.

Recommendations for replacement 6 inch speakers with the Jensen AWM 968? They are for my rv, and are the only speakers in it. Thanks in advance for any help!
In-car entertainment systems, especially the types chosen for camper vans, etc., are often capable of quite high power outputs and usually need speakers capable of being driven at those high power outputs without damage.

The trouble is, such speakers usually don't sound so good at the very low volume settings needed for evening and late night use in a campsite environment to avoid annoyance to neighbours.

It is a big problem choosing speakers that sound good at low volume and yet can withstand the higher volume needed to overcome the wind and road noise of driving. There have been many technological advances in speaker design and a hi-fi specialist will undoubtedly be able to make suitable recommendations that are resistant to damp conditions, long-lasting and with cones free enough for good reproduction at ultra low volumes but robust enough to withstand high power outputs and such drive units are likely to be fairly expensive.

For myself I would choose to use a dual speaker system with a multi-speaker system comprising several low-powered speakers strategically placed for low volume use and a fairly standard high-powered system for normal use and a selector switch.

Guitar amp had high volume feedback now the sound is different
The short answer is yes. You didn't tell us what make/model/speakers, but if it was really high volume you may hsve blown a speaker. Of course, if you let it get out of hand you can damage your ears.

High pitched noise in speaker
Could be an alternator problem. Bad ground wire or just old bad wiring.
If you have an amp then the power wire is to close to the speaker wire.

My speakers just out of the blue began to buzz in the middle of a song. The volume was low & did not seem to effect the buzzing - after I turned music off speakers began to make a high pitched ringing...
I've never worked on this model so I can't give you a definite part value or location, but you'll probably find a bad filter capacitor (or possibly more than one) in the power supply. The power supply converts the AC power line voltage to the DC (direct current) needed by the electronics. If the filter capcitors don't work, the result isn't smooth and steady, and the result is an annoying hum. You're probably hearing this.

It's possible to replace the bad capacitors, but it's not always easy. The people who make computer speakers don't often design them to be serviced, and sometimes it's a challenge getting into the power supply. But if you or someone you know with some electronic soldering skills is willing to give it a try, you might be able to bring these speakers back to normal. Good luck and thanks for using Fixya!

PYLE PT2001X 3300 Watt Professional DJ Power.just had question about running this amp in bridged mode 4 ohms, here's some amp info 3300 watts total power bridged in 1 ch only.1650 each ch in stereo mode...
Hi,

In bridge mode the minimum load will be 8 Ohm.
If you are using 4 Ohm speakers, it will mean you will give each side of the amplifier a 2 Ohm load.
Thats to much for this model.

Kind regards,
Gerard

Amplifier Screech at High Volume
What you're hearing is FEEDBACK caused by the nearness of the guitar to the amplifier speaker. Always mute it when not in use, or don't move it close to the guitar amplifier speaker when unmuted.

Usually, even though you hear a high-pitched screech, the problem is actually caused by low frequencies, sometimes below the human hearing threshhold (i.e., subsonic) because they are more omnidirectional and thus more easily easily can loop between input (the guitar pickup, especially on a hollow-body guitar) and output (the speaker). The screech frequency is determined by the distance between input and output, determining how quickly the output reaches the input (then loops around through the amplifier). Therefore, reducing the BASS a bit will often alleviate some of the problem.

This is basically the same type of feedback heard when a microphone is turned up too loudly or the mic is pointed at the PA speaker. Avoid those actions and your feedback will be minimized.

Only time and experience will allow you to automatically take actions to avoid feedback. I worked in the San Francisco Bay Area as a manager and sound man for rock bands and several nightclubs for 22 years. My college major was Physics (which includes acoustics).

Keep on rockin'!

In modes other than DVD (i.e. video, sat, and tuner) there is a high-pitched squeal coming from the speakers. What could be causing this and is there a fix?
check to make sure you dont have any electrical wires running near your speaker wires that can cause that kind of feedback make sure your keep your volume down when your not listening to it
