Hi There,
It sounds like you may have some faulty wiring running from the stereo to the speakers. This is somewhat common and can happen for many different reasons. Often times, when the wiring is faulty producing a bad connection, you may hear the sound coming from the speakers intermittently as you describe. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

Check each set of wires and speakers to be sure no wire or lead is connected to a chassis ground. The radio will see this as a short and turn off the internal amplifier causing the on but no sound issue. Each speaker connected to the radio needs dedicated positive and negative leads from the radio to each speaker.
Newer models are equipped with a digital infotainment system. If you notice you are experiencing issues with your information display or the Mazda navigation system from the model years 2014-2023 models, here`s a quick fix. Reset your radio by pressing the music, navigation, and volume buttons at the same time.
Although the car loses nothing in handling, Mazda managed to smooth out the ride a little. But the RX-8 R3 loses some tech in translation from Japan to the U.S., giving up a navigation system. But the U.S. version keeps Bluetooth cell phone integration as a standard feature and adds a 300-watt Bose audio system.
Audio. Make sure that the speaker setup microphone is not still connected. Confirm that the connection between the output jack on the device and the input jack on this unit is correct. Make sure that none of the connecting cables are bent, twisted, or damaged.
Ensure the speaker balance on the stereo system is set to the center position. Ensure the speaker wire is connected properly to the back of the stereo system. If the issue is not resolved, replace the speaker wire. If the issue is still not resolved, remove the speaker connections from the stereo system.
Press and hold the audio system`s volume/power knob for about 3 seconds or until the system resets. Press and hold down the audio system`s volume/power knob for at least 7 seconds.
is 145 miles per hour. vehicle lineup from 2003 to 2012 and is classified as a sports car. It is fitted with a 1.3 liter Wankel rotary engine and is available with a 5-speed or 6-speed manual transmission or a 4-speed or 6-speed automatic.
Blown Fuse

The most likely reason for your radio`s sudden death is a blown fuse. All car radios have at least one fuse that protects it from power surges coming from somewhere else in the vehicle. The first thing you should do when your radio stops working is check its fuses and replace any that have blown.

A Fuse Needs to be Replaced

If too much current is sent to the audio system, this fuse will blow out and disconnect the circuit to save the main radio. On newer models, there are a variety of fuses for the entertainment system.

Radio noise is a combination of natural electromagnetic atmospheric noise (“spherics”, static) created by electrical processes in the atmosphere like lightning, manmade radio frequency interference (RFI) from other electrical devices picked up by the receiver`s antenna, and thermal noise present in the receiver input …
The two main causes of a persistent humming or buzzing are: a bad audio cable connected to the amplifier, or. there is electrical noise being passed through an audio cable into the amplifier.
Try these steps: Check your speaker and headphone connections for loose cords or cables. Make sure all cords and cables are plugged in. If you have multiple 5mm jacks to plug into, especially on a surround sound system, make sure all cords and cables are plugged into the correct jack.
Nearly all the latest Mazda vehicles have the Bose® Premium Audio System.
Disconnect All Previously Paired Devices

To reset the speaker, press and hold the Bluetooth and power button (sometimes it can be interchanged with the volume button) at the same time for a couple of seconds, up to 15 seconds.

In 2022-2023, most drivers know that Mazda vehicles come with Bose sound systems; however, that`s just the start.
What happens when you reset an ECU? By resetting the Engine Control Module, you can return your car to its factory settings. This will erase any error codes or radio stations that were stored in the car`s memory. Furthermore, it also affects the car`s performance for a while, until it adapts to your driving style.
A car`s ECU, or engine control unit, should actually never have to be reset. It may, however, help with such issues as a stubborn check engine light or restoring your car to factory settings.
Start your engine and turn on your car`s audio system. Turn it off if it asks for “code”. Press and hold the radio button for approximately 40-50 minutes. During this interval, your car`s audio system will ignore the code and start playing music.
The largest recall of the RX-8 was for cars built between 2003 and 2004. More than 15,000 cars were recalled to fix a problem with the exhaust system that could cause a fuel leak. It was discovered that parts surrounding the exhaust could melt and the heat could affect the fuel tank.
The car is a good car if your not expecting fuel economy, it looks stylish, has great performance and also comfortable for the customer, not so much for back seat passengers. The car is very unique in styling and components. I love it.
The car could also reach a top speed of more than 170 mph (270 km/h), making it the fastest factory RX-8 ever built. The body color choices for the Spirit R were limited to Aluminum Metallic, Sparkling Black Mica, and a special color, Crystal White Pearl Mica, exclusive to the Spirit R.
While the Mazda RX-8 certainly looks cool—it`s not a good first car for novice drivers. Firstly, the RX-8 is a sports car, so we`re guessing your parents wouldn`t want their teen driver zipping in and out of traffic, as the temptation to see how fast it can actually go would be great if you`ve got the need for speed.
The estimated cost to maintain and repair a Mazda RX-8 ranges from $95 to $2697, with an average of $308.

Due to this, it`s predicted that this model will appreciate in time. These sports cars have reached an all-time low and can be picked up for less than €1,000 today. The RX-8 was and still is great to drive. Equipped with a manual gearbox and rear wheel drive, the RX-8 is sure to increase in value.

the most relevant questions and answers related to your specific issue

I have a factory Bose radio in my 2009 Mazda RX-8. The radio works but I cannot heary any sound. What could be the issue?
ANSWER : Hi There,
It sounds like you may have some faulty wiring running from the stereo to the speakers. This is somewhat common and can happen for many different reasons. Often times, when the wiring is faulty producing a bad connection, you may hear the sound coming from the speakers intermittently as you describe. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

Radio only works through steering wheel controls
ANSWER : It sounds like the radio unit in your vehicle may have partially failed to where the controls no longer work. I would recommend having your radio inspected by a qualified professional. This inspection may involve the removal of the radio and some sort of bench testing with a high tech scan tool or machine of some kind that is used specifically for the testing of automotive radio equipment. This electrical inspection may also include using a digital multimeter to test certain wires that connect to your radio that may control the use of the buttons on the face of the radio. If the inspection shows that your radio controls have shorted out, replace the radio if necessary to regain this function in your vehicle.

My radio has stopped working it shows like it is working but have no sound…
ANSWER : Hi there. In most cases, when the sound option of the radio is not working, it’s due to an exposed speaker wire or malfunction of the unit itself. Most factory radio’s are powered by a single electrical relay and fuse connection. So, it’s probably best to have a professional mechanic complete a radio not working inspection to determine what’s happening with your stereo and what repairs need to be made.

An inconsistent starter motor that occasionally works perfectly now will not work. Then engine will not crank at all.
ANSWER : Hi there. It is possible for the starter to fail. But before replacing the starter, make sure that the battery cables are tight and clean. Then check the starter relay and make sure that the relay is clicking. If the relay is not clicking, then check for power to the relay. If there is power to the relay but there is no click, then the starter relay would need to be replaced. If there is no power to the relay, then either the wiring from the relay to the ignition switch has a break in it or the ignition switch is failing. If there is power to the relay and power to the starter motor, then the starter motor needs replaced. If you need further assistance with your no start issue, then seek out a professional, such as one from Your Mechanic, to help you.

Car radio will not pick up radio stations.
ANSWER : There are multiple issues that could cause a radio to not pick up an AM / FM signal. In most cases it’s due to faulty wiring, a loose ground wire or the wiring running to and from the antenna. However, it’s also possible that an internal component inside the radio such as an electrical relay has been damaged. It might be best to purchase a new tuner; as diagnosing and fixing this issue would most likely be more expensive than the cost of buying and installing a new one.

Windshield wipers stopped working. They’ll suddenly stop working then suddenly start working again. Has been happening for a week.
ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Heater works when moving. Stops working when sitting at light. Makes a gurgling sound. What could be the problem?
ANSWER : Hello. Thank you for writing in. The most important part of the heating system is the coolant. The first step to take is to make sure your coolant level is topped off in the radiator and the overflow tank. If the level is low, you need to find out why. At that point there is likely a leak in the system. Once you have the leak repaired, you can retest the heating system. With the coolant full and the system leak free, the next place to look would be air caught in the system. You will have to go through the purging process. A clog can also similar symptoms, and a cooling system flush may be beneficial. With the age of the vehicle, these are relatively common maintenance issues.
