Generally speaking.. disconnect speakers then retest if goes out bad speaker... but most likely you have a shorted output transistor.... remove bottom cover and look good at all transistors mounted to the sides... alot of times you will smell and see burnt up triac transistors.. if all looks good then take ohm meter and check finals for shorts... sometimes you have to remove some finals as in if one is shorted they all will show a short as they are tied together

Turn key off and removed. Power stays on radio ,heater.


Hello? It sems that the wiring is not done properly. Make sure that the radio wiring is done correctly. We have 3 wires that are very important when it comes to radio wiring. We have vcc,acc and ground. Vcc has to connect to battery direct, this helps keep radio memory on all the time. acc goes to acc and this switches radio on and off when you turn the key. Ground goes to earth. The wiring harness color code depends on different radio makes and car makes as well but a professional should help you with this.

Air bag light comes on then goes off on its own


Most of the time it's the clockspring ( coiled wire connection between the steering wheel tand the steering collum) this part wears out after awhile and the wires start to fail. If the SRS computer does'nt(see) the resistance of the fuse( detonator) inthe airbag it'll turn the light on if it goes back in range it'll turn the light back off. If you have the tools and experience to remove and reinstall the steering whell and have done jobs like replaceing lock cyclinders and or turn signal switches and feel confrotable doing them this is in the same area. If you have never pulled and steering wheel you'd best at least get help from someone who has done this kind or work before and is confident in useing the tools required or hire the work done by someone who has done this work before.

Very low miles 1995 Hyundai ELANTRA 1800 cc 16 dohc. CHECK ENGINE LIGHT frequently comes on. Stop engine, retart after light goes off...sometimes goes for hundred miles and three times new timing belt...


If the timing belt keeps breaking and bending valves, the timing belt and cylinder head repair is not being done correctly. It's as simple as that. Are you changing the tensioner and idler pullies when replacing the belt? Is it timed correctly? Was the timing belt tension adjusted properly? Were the cam journals checked for damage? If not, you are asking for another belt failure.

If you want to know why the check engine light is coming on, you will have to ask your engine computer. Every time the light comes on it is storing a fault code to tell you why. You must scan your engine control module to retrieve the fault code(s) so you can get it properly diagnosed and repaired.

I have a 1000 watt sony explode mx-2165gtx and i have 2 12inch rockferd subs all hooked up in my truck. i turn on the sterio and turn it up just a little bit and it goes into protect mode i cant figure out...


Sounds like you're overloading the amp. Which rockford subs are they exactly? I can find the specs and see if theyre just too much for the amp or you just have to hook em up to the amp different so the amp wont go into protect mode

I cant get both switches to work properly one minute it turns the light on the next they done work. is the red wire suppose to hook up to the black screw


The key to three-way switches is the dark screw.
And different brands of switches put dark screw on different side of switch.

So, lets get out of this mess with a bit of testing.
You have two switches with 3 wires on each switch for a total of 6 wires.
Take out both switches and separate wires for testing.

Turn on power and test each wire to bare copper wire.
One and only one wire will test Hot.
The hot wire goes to dark screw on switch1.
The other two wires in that box go to either screw on switch1.
One switch done, one switch to go.

Move switch1 lever to down position.
Turn on power and test 3 remaining wires.
One wire will test hot. Mark this wire.
Move switch1 to up position, and test 3 remaining wires again.
A second wire will test hot. Mark this wire.
The 2 marked wires attach to either brass screw on switch2.
The third wire attaches to dark screw.
Both switches done.

Boss d600.2 goes in pertect mode when volume turned up at 2ohms. why its suposed to be 2ohm stable


Unfortunately, 2 ohms isn't necessarily 2 ohms.

A speaker's impedance varies with frequency AND the enclosure.

NEVER believe these manufacture's specs for auto audio things.

If you overdrive a speakers so that he cone moves out too far, the impedance drops.
