My drivers side front speaker and the tweeter have both quit on my 99. Any idea's on whether it could be the factory amp/crossover or just pinched wiring somewhere? Thanks

 

My door speaker did that. The connector at the speaker no longer had continuity so I replaced the factory 'AudioLatina' brand with some inexpensive Kenwoods. Sounds better than ever.

 

it could be the stock radio they are not the greatest units i lost the left side on mine on the way home when i bought the truck

 

If you need wire identification information:

Just pull the dash bezel off and the radio is easily accessible. Check continuity of individual wire sections it might tell you something.

 

My factory radio had the cd player die before the truck was 2 years old. I've had aftermarket in it ever since. I just put another in it back on the first week of Oct. with more options than the previous unit. Just tired of not having the door speaker. That wiring diagram should do the trip. Thanks
