No sounds out of midrange and high speakers

First check whether the connector for the speaker wires is firmly plugged in behind the radio. Try unplugging and replugging to make sure. (Note: the connector may be attached to the radio or it may be on the end of a short length of wire.)

If the speakers are firmly plugged in and you still don't get sound, the next step is to test the speakers. Do this by unplugging the wires behind the radio, then run a meter across one pair (for one speaker) to make sure you don't have an open circuit (broken connection). Alternatively, feed audio from the speaker outputs on a boombox or other stereo to that pair of wires. If you don't get sound or if the meter says there's an open circuit or direct short, either the speakers are bad or there's a broken wire between the radio and the speakers. Most bad connections happen at one end of a wire or the other, so look at the connectors at the radio and at the speakers.

Finally, if the speakers do check out, you'll have to test the car radio itself. Run a pair of wires for one speaker from the radio's outputs to an external speaker (any working speaker will do). If there's no sound, your radio is broken.

Of course, the easy way to do this is take it to a place that installs car radios. They can check it out quite easily and make recommendations. Don't take it to a Chevy dealer. They'll charge you a fortune, and if the radio is bad, they'll sell a refurbished unit for more than you'd pay for a high-end Kenwood or Pioneer.

if im understanding correctly what you wrote. you hooked up the headunit to the car and no sound from speakers, then you hooked up a single house speaker up and that speaker works fine. the Ohms on the car speakers might be too high, but most likely sounds like the wires to the speakers are bad.

Some things I would check are do you have blue tooth in operation. Do you have any form of michrophone in the cab as it sounds like a feed back problem coming through your speakers. Talk to a radio techie to see what he thinks

may be the radio itselt..test the speakers with another radio remotely at each one..Im betting on the radio...

So everything is coming on but you have no sound from anything?If that is the case you may want to check the amp fuse.The car has a factory amp i'm trying to remember i think it is in the trunk.Look in your owners manuel for the fuse box location.If the fuse is good then the factory amp may be bad.Or you may have a blown speaker that is showing a short and putting the amp into protect.If the amp and or speakers are bad i highly recommend just buying after market speakers/amp.The price for the factory equipment is very high and there labor rates even higher lol.Plus if properly installed you will noticed better sound from the after market stuff as long as you get brand name equipment.Go to a well trusted audio shop in your area they should be able to see if it is a speaker or amp problem if your fuses are all good.They should be able to test the impedance of the speakers at the amp for you and see what is going on.

chances are the speakers are already busted or the connecting wires are loosened. speakers are busted if a sudden high volume was induced as this will give a sudden surge of high current. You can dismantle the whole radio and look for a loose wire connecting the speakers terminal.

It sounds like the Bose has a problem internally. It may just be a resistor or fuse.

Sounds like you might have blown a speaker. These days they are often 3 in one assemblies and you're probablyjust hearing the tweeter while the bass and midrange are gone.

The sure way is too use am ohmmeter and look for between 2 and 8 ohms.

This is why it pays to buy good warranted speakers for 5 years like some companies offer. You pay more up front but in the long run its usually worth it. It's also why most speakers are only 30 to 90 day warranties -- They're one of the most blown up things in the consumer industry.

I went to college for electronics, BTW.

sound like the head unit's out put mosfet is going bad, but i have also ran in to this problem when it was a speaker wires shorting out. so first check the connection on your rear speakers.

Hi

You will need to take the dash cover off. Just get a #20 torx and you can do it. The speaker is attached to the underside of the panel.Due to design choices like cheap paper cones and foam surrounds, after a few years of use, midranges don't sound great and almost invariably disintegrate. Then you get awful buzzing and crackling.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
