Sounds like DC leakage....pre-drive and/or output transistors (or IC) becoming intermittent often pass DC voltages to the speakers. The "pops" you hear are these DC pulses being passed to the speakers and the "cutout" is the protection circuitry doing its job...protecting the speakers. Speakers want AC voltages...plus voltages moving the cone in one direction, and a negative voltage moving it in the opposite direction. DC voltages push the speaker cones in a single direction and hold it there until it fails. The bad news...it's repair shop time.
The speakers or the connections to the speakers are loose. Usually the speaker's paper cone is torn. Check to see where the speakers are mounted. Usually you can hear them or see the cloth grill covers. Most of the time they're in the bottom of the door panel or in the kick panels.The speakers can be checked out by removing the door panels, bottom half at least. If the car is more than 15 yrs old the speakers will have to be replaced. But if the car is newer, it could be in the radio itself. So don't be too quick to remove the door panels.
Hope this helps.
First you have to remove all of the bottom rubber feet, don't worry they are glued to the bottom, then with a sharp knife, remove the plasticdecal where the USB, AC and video plugs are. Pry it off from one corner then work your way all around, there you will find three more screws that will release the board. Good Luck!!!
Really Thankful for the detailed description for the Speaker Repair.
It really helped me a lot. I have a unusual situation here with me. I have dissected the whole console and found the outer band of the speaker has just come off....have attached photos to make it clear. does the outer speaker cone will make a difference or i will have to replace the speakers itself.....when i checked pressing the speaker down and played the distortion had gone....but while playing without holding the distortion would come back....Hope you can help me in this situation....Thanks in Advance.....
You can remove the grill in front of the speakers by using 2 mini mini screw driver one to pry it out little by little while the other to hold it from going back in .There are noscrews holding the grill.They are held by 4 clamps which are the grill inner end bend abit out thats all.
So if you pry it will give way not to worry the grill is made of a hard aluminium material it just needs care in order not to scratch the paint surface and aluminium ring around it,use a soft cloth to protect the ring when prying.Remember this aluminium ring wont come out its only the grey grill that will.
This thing is worth saving because it sounds great even after speaker repair.Yes where i am in Idonesia there are people who are profesionals at repairing speakers that are torn out like our harman.(torn due to age around the speaker cone).i paid 15 usd to get the both of them repaired and its the best 15 dollars i have ever spent.Cause now it could not have sounded any newer the bass is back the balance is pure harman again
Remove the protecting grill in front. Check if the cone is still connected to the rubber band. If not, remove the screws around the speaker. Open the casing itself. Do not forget the screw in the middle of the battery compartment. Remove the bottom cover. Disconnect the 2 wires on the speaker and take out the speaker. It will come out with the plastic protection around it. Looking at the cone now, push up the Carton cone and keep it in place by putting some tissue paper or small cloth underneath. Clean the cone first. Use some rubber cement on the outer edges of the cone and press the rubber back on the cone. Let it dry for an hour and then remove the tissue / cloth, so the cone goes back to its normal position.You can use some extra rubber (those pre-glued strips that you would use to fix a bicycle tire) to make it extra strong. Remount everything back in place and voila....it works again!If your cone is not damaged, the casing most probably does not seal good anymore. Tighten all screws a little more and use plastic electrical tape all around to seal all joints. The bass is produced inside the casing itself and pushed out via a horn. If it is not closed off well, your bass sounds grumpy.
This is either caused by something in or on the cabinet vibrating... grilles and logos are common problems OR one of the speakers is blown OR you have contamination behind the grille. If you have driven the speaker too hard, the voice coil can distort from heat and rub the magnet pole pieces. You can tell this by removing the grille and GENTLY moving the cone back and forth. If you can feel any roughness, you need to have speake re-coned.
A common reason for 'distortion' with all bass amps can be either that the screws holding the speaker unit to the cabinet have worked loose or that there has been a build up of dust particles in the corrugations around the edge of the speaker cone, which rattle especially on the lower notes.
The solution is simple - remove the front grille and check the screws are tight. Use a vacuum cleaner to remove dust from the rim of the speaker cone.
Some speaker manufacturers design their boxes with non-removable front grills. Be thankful that you can remove the back because I've seen these sealed as well. Once inside, the speakers should be mounted from the inside (mounting screws on inside) compared to front mounted. IF they are not then either you're not using the proper method to remove the grill OR it's glued in place and will require breaking the glue bond to release the grill. One note to remember...non-removable grills can mean the manufacturer has something to hide.
