Right front channal buzzes

You might have blown the speaker. This happens when you play things too loudly and you ruin the speaker inside. You can test this by playing something with a decent amount of bass and turned up a bit. If you hear like a "rattle" in the sound or like something isn't right in the heavy bass notes, then you definitely blew the speaker out. This isn't a tragedy. They're fixable if you bring them to a place that repairs speakers. But I would definitely test it first by hooking it up and playing a loud song with a lot of bass. Hope that helps a little! Please rate my solution!

This is a grounding issue either between pieces of equipment or inside the receiver itself.
There are other possible causes, but this will almost always be a grounding issue.
I recommend unplugging everything and hooking it up piece by piece till the buzz return to isolate the issue.
IE - start with nothing but the receiver and speakers hooked up. Turn on the radio. If the speakers buzz, the receiver has an issue and needs to be repaired or replaced.

If there's no buzz, hook up the DVD player. If the buzz returns, there's some issue between the DVD and the receiver....
If the buzz hasn't returned, hook up the.....<insert name of next piece of equipment here>
you get the idea.

yes you are right i aslo got problam in that..........join speaker lead in audio out.......and join green connector at the back of comuter <in which you insert the lead of speakers> to audio in

There may be any of several problems.

If you send high pitch signals to a speaker designed for lows, it can cause waves to propagate outward causing a buzzing. Look up the specs on the speaker and verify that your crossover cuts off well below the high end frequency for this speaker.

Another problem can be due to the mounting which can resonate. This should be mounted on at least plywood that is 1/2 inch or more thick. It needs to be wood as plastic or metal will rattle and buzz.

Another problem can be the wiring near this can rattle and buzz.

Check out these possibilities.

Yeah problem solve it was tricky. All I did to resolve the problem was ah ah not so fast if you want the answer it'll cost you only 9.95 one time fee. So feel free to e-mail so I can tell where to send the check. This reply is for fixya.

While the rear subwoofer does fail, it is often misdiagnosed because of a rattle in the vicinity.

Try removing the little fold away hooks near the subwoofer (philips screws) and see if your problem goes away.
If it is still there, loosen the panel and see if it goes away.
If it does not, more than likely the speaker has in fact failed.

Most subwoofer buzzes have been either the little fold away hook or the wire harness just behind the subwoofer.
Actual speaker failures are much more rare.

The first thing I would do is pull the stereo out of the dash and unplug it . If the buzzing stops the stereo is bad get a new stereo. Its not hard to remove the stereo. Right above the cup holder there is a small cover you need a very small screwdriver to remove it . Under that is a few screws take those out then grab the plastic cover that runs around the stereo and pull towards the back window it simply pops off (No screws) After you remove that cover you will see 4 phillips head screws that hold the stereo in remove them. Last slide out the stereo there will be 1 plug with alot of wires that is the power and speakers . Unplug it . The other round plug is the FM antenna

FYI - I just took our 2004 Sequoia in because of speaker rattle coming from the front door speakers. Before I could tell them the problem, they guessed what it was. They see loads of Sequoias and Tundras with JBL systems due to the front door 8in speaker, basically, coming apart. His suggestion was to replace only the bottom 8in speaker, because the top tweeters usually are in good working condition. There is a minimal failure rate on the tweeters.

If you go to anyplace that installs car stereos you can purchase an installation harness that will connect directly to your factory harness in your car. That way you would only need to wire your Kenwood harness to the instllation harness and that is just a matter of matching colors from the Kenwood harness to the installation harness. All you need to do after that is plug it in.

The wiring on the Kenwood harness is as follows:

yellow = constant 12 volts
red = ingnition (12 volts when key is turned on)
black = ground
white = front left speaker positive
white w/black stripe = front left speaker negative
grey = front right speaker positive
grey w/black stripe = front right speaker negative
green = rear left speaker positive
green w/black stripe = rear left speaker negative
purple = rear right speaker positive
purple w/blackk stripe = rear right speaker negative
blue = power antenna
blue w/white stripe = remote amp turn on
brown = phone
orange w/white stripe = illumination

make sure that your system volume is turned up and that the speakers are turned all the way to the right.
