You most likely have a bad ground wire, or too small of a power wire as well. Might also want to check on how they wired the speakers as well

You have a ground loop problem that whining is called radiated engine noise.

I get white smoke from exhaust and a smell off burning oil, not losing any oil pressure, its a bmw 320d , can any1 help

You should get the car into a shop and have a compression test done. For some reason your engine is burning oil and a compression test that will show leakdown can help pinpoint the problem. Hope this helps.

2000 BMW 323CI clutch smell

The smell of a burned clutch is one that permeates the car for quite sometime after the incident. It may take as long as two weeks for the smell to alleviate.

Meanwhile if the car is shifting normally and not slipping I would say the clutch is ok.

Kenmore Electric Dryer Series 80 Model

Disconnect the dryer from your vent completely,. pull dryer out 3 ft. from wall and test to see if the smell continues, You have to test for a few minutes to clear out any burning lint from vent restrictions. If the smell hoes away then you know you have venting problems. Also check on the grate that covers the element( the part you look through when you see the orange glow from the element) sometimes plastic or clothing burns onto this grate and needs to be cleaned off. I the smell remains, you will have to tear down the dryer to see if you can find the cause of the smell.

Engine running hot


The first option is to to flush the coolant and replace the thermostat, if you are unlucky and this doesn't get your problem solved then the next step is your water pump.

Volume turned up, kenwood shuts off briefly...

I had this same exact problem when my last older Kenwood Marine stereo cooked itself while I had it up loud for a few weekends on the lake. (smelled like it had burned inside). I went out and bought a new Kenwood KMR-550u stereo deck. (I do not have an additional amp). I hooked it up to the exact connections where my older Kenwood stereo unit had been hooked up, as I never had a problem with this for the past three years until it failed after smelling of burning elelectrical. I had chalked the problem up to heavy rain we had one day. Every time I turned up the volume, sometimes up to 27 out of 35 possible, or 29, or 32, the stereo would suddenly shut off as if I had turned it off. After a few seconds the stereo would come back on, but unless I was quick enough to turn down the volume it would do it again right away. Of course on a boat, we were beached in a cove and the engine was not running when I encountered this. I searched the internet finding hundreds of similar complaints and several dozen theories of all types, but only a couple that pointed me towards the power (voltage) idea as the problem. I put a volt meter on the positive & negative wires powering the stereo. I watched as I gradually turned up the volume, the voltage on the power wire gradually decreased from 12.5 volts, down into the 11 range, and as it hit 10.9 or 10.8 volts it shut off typically around a volume of 32. The red power wire in my boat that never seemed to have an issue with my old stereo until it fried was determined to actually be inadequate for the power flow for the new Kenwood, and probably was the culprit of my failed older unit. I offer this sound advice: Run a new pair of positive & negative wires directly from the battery (with an appropriate fuse of course (the deck has a 10 amp fuse in it's back so I would use that at the battery) to the stereo. Check the voltage as you turn the volume up into the high 20's and low 30's to ensure you are still getting voltage in the mid to high 11-12 volt range. The stereo is designed to require a minimum of 10.8 volts to operate, and when it drops below that it protects itself and shuts down.
