i have a 2002 dodge ram quad cab 1500 4x4 ive installed a head unit that i had and it was working great.. i also installed two 10 inch subs and an amp.. as well as two new infinity rear door speakers... the problem first arose about a month ago where the rear speakers would start crackling but if you turned the radio really loud the carckling would stop for a while so i purchased new speakers for the rear doors installed them and bam same thing.. now im getting the same crackling from the rear still... as well as the fronts.. and sometimes i lose sound from the right side and sometimes from the left side... the truck came with the Infinity package so it has an original amp powering the door speakers which i havent touched yet.. could it be a problem with the head unit?


note: while stereo is turned up loud all speakers work fine and there is no crackling

 

its your head unit.......

 

make sure all the connections are plugged in tight. check behind the head unit to see if there is any loose wires from the harness.

It seems like your wires are getting pinched someplace and so ur losing quality

 

First thing that came to my mind was something grounding out.

 

I had a rear speaker in my mustang that one of the terminals kinda broke and was dangling...it came to rest against the frame of the car so it kept crackling and cutting out. However I would totally bypass the factory amp. It's a total piece.

 

im gona try a different HU and as for bypassing the factory amp... would a hu be able to push the front door speakers? their more of a sub woofer seeming as how they only produce bass notes...... any other suggestions guys.. i installed the HU myself.. the wiring job i did is guaranteed.. solder and heat shrink cant fail... but none the less i will double check anyone got the specs for the front door speakers? truck has infinity speakers from factory except the rears

 

Voice coils bottoming out against the magnets.

 

.............. that doesnt even make much sense.... i know what that sounds like and its not that...... remember the volume can be turned right down to 0 and i still makes the crackling sound
