Suddenly, my outdoor speakers sound kind of "muffled"

Please illuminate me explaining the word "Muffled" means and i will be glad to help you out...

It sounds like the speakers ore out of phase. You need to make sure that all the + connections are connected to the + and the - to the -. If one of the two are reversed there will be cancellation of the sound. All the speakers must move in the same direction all at the same time.

Hi,
firstly you could be experiencing "phasing" as you may have not spaced/set up the speakers properly. Also make sure plus on the amp goes to plus on the speak and ten - to - on the amp and speaker. cross them over at any stage or pair and again you will get your problem.ugest
It could also be you sre over driving your amp. How many ohms is each speaker and how many ohms is your amp capable of? 6 speakers to one stereo amp with one speaker out is very rare and usually quite damaging to equipment.
personally I would suggest one pre amp (to plug sources into) then 3 stereo power amps (one for each pair of speakers)

Speakers have a unique RF frequency that needs to pair with the receiver (kind of like a blue tooth headset with a cell phone). At times, the signal may reset, so, you may have to go through the initial pairing sequence. Try this:
1. Unplug rear speakers
2. Make sure the sound signal connector is plugged in to the back of the system properly.
3. Press and hold the ID button for 3 seconds until the blue LED light flickers.
4. Connect the power chord to the rear speakers.

Hello dan5260,

Your audio processor might be going bad or at least one of the capacitors might had malfunctioned.
We are actually not talking about much expense in fixing this problem. At my shop here how the pricing would go:

Parts: $20.00-$30.00
Labor: $60.00 per hour (1 hour limit) Total $120.00
Starter Fee: $30.00

So total will be about $170.00 - $180.00

This is just an estimate based on my shop, your local shop might charge more or less.

I hope this helps,

Thank you,

Assuming you've already checked all your wiring, it sounds like a problem in the amp circuitry. Would you say it happens when the amp heats up? I'm guessing an input opamp circuit is messing up when the amp gets hot. If you are electronically inclined you could open it up and look for a poor solder joint. Other than that you will likely have to get it professionally serviced.

Hi airnurse

If you are using a cassette deck for a source of music, then it will have dirty heads. This can be cured by using a head cleaner cassette. Muffled sound from the loudspeakers usually points to a faulty high frequency driver(tweeter). Is the sound muffled on radio or other sources as well. If so, then you have faulty tweeter(s) to any speakers that are muffled.

Of course in saying that, you should check that someone has not just turned the treble control all the way down, or the bass control alll the way up :) Pays to check.

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

If you have a Ohm Meter, check the resistance to the speakers. If it is very high, the speakers are burned, (or the crossover is (just capacitors, and resisters...cheap)). If it is close to 4 ohms check the wiring and connectors..to and at the speakers, most likly the receiver/amp is not blown.

check to see if the radio is clear. If it is it may be the signal going into the amplifier. if it is muffled as well, depending if you have an Equalizer hooked to the unit. This also could cause the problem. Finally check the bass, treble balance and volume knob but turn them back and forth while unit is on and see if signal clears up momentarily. if this is the case the control knobs need to be cleaned. Also spin the connection jacks {RCAs} in the rear and see if this clears it up. If not you may have to have the unit serviced by a professional.
