AS WITH ALL MY VIDEOS I TRY TO GIVE THE MOST INFORMATION IN THE LEAST AMOUNT OF TIME AS POSSIBLE SO I DON’T WASTE YOUR TIME. IN THIS VIDEO I HAD THE RIGHT FRONT DOOR SPEAKER BLOW OUT IN MY DAUGHTERS 2004 NISSAN XTERRA SO I REPLACED THE FRONT AND REAR SPEAKERS. I GO OVER THE REPLACEMENT OF BOTH SETS OF SPEAKERS INCLUDING THE DISSASEMBLY & ASSEMBLY OF THE DOOR PANELS ALONG WITH THE TRIM IN THE REAR OF THE VEHICLE. I GO OVER HOW TO CHECK THE POSITIVE AND NEGATIVE ON THE WIRING OF THE VEHICLE HARNESS AS WELL AS HOW TO CHECK THE SPEAKERS FOR POSITIVE AND NEGATIVE SO YOU MAKE SURE YOU ARE HOOKING THEM UP CORRECTLY. I ALSO GO OVER SOME HELPFUL TIPS IF YOU ARE REPLACING THE SPEAKERS ON THIS VEHICLE THAT WILL SAVE YOU TIME AND FRUSTRATION.
