Feedback/maxing out speakers.....

Basically when i turn my stereo on it seems as if everthing is fine. at medium volume it sounds really blurry . and when i turn up the volume on either the headunit or the gain on the amp it starts to feedback and it eventually builds up untill the subs are maxed out. if the volume is completely down and i slowly turn the gain up it does this as well at about half way. i've tried moving the ground and replaced the rca cables and the speaker wire going to the subs. any help is GREatly apreciated !

Volume button sticks and raises to max level and cannot be turned down.

It sounds from your description there is a fault in the audio section electronics rather than with the button.

My speakers in my 2003 Silverado started to fail at about 5 years old. I just replaced them with all new speakers. They would come and go erratically and sounded horrible.

I inherited a technics SL-6 turntable system and a very old sears audio by fisher am/fm stereo receiver along with 1 pair of kenwood ks-401ht front speakers and cant get any sound. I have the technics...

Your connections seem to be right.

Let's distill this down to its simplest configuration... does the onboard FM produce sound? If not, nothing will.

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING.

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

Volume Level on Memorex 9299M 4-in-1 Turntable System Way Too Low

It's the nature of the all-in-one turntable beast to be low fi and low performance. Too much volume and vibration would feed back through the turntable.

It does have a Line Out that you could slave over to REAL electronics and speakers.

Tinny sound from L-310 SW's

This might be helpful. Most stereo receivers have 2 sets of speaker outputs, A and B. Each have outputs for left and right speakers. On the front panel of the receiver, there should be a switch to turn on/off speaker A/B. When using both A and B, (a set of speakers on each A and B) you will lose a bit of volume.

Another possibility is, if the speaker cable length to your covered porch is a long distance from the receiver, you will lose some power from the receiver. Try using a thicker gauge speaker cable for longer cable runs. Try 14 gauge or 16 gauge.

Speaker will not turn on

Actully the problem is your speaker which is shorted. The speaker assembly or the one who crashed out always, when you excited the volume to max it feedback to amplifier Ic to cut the fuse blown. The amperage goes up and sent to either left or right amplifier power supply.
Even you replace the fuse with a new one it will repeat the situation and story.
later sooner it will damage more.

Sound feedback

Are those add-on speakers, not clear on that? Feedback is almost always a problem involving speakers and microphone being to close together or mic being to hightly modulated. It is possible that power lines being to close could induce a hum of varying severity.
