Q: on mar 20 840 am yoyo22 y...@yahoo.com wrote heres the story last week the audio in my truck went out. i have a 2005 dodge ram qc with infnity 7 speaker system. the stereo in dash appeared to be finelights display etc but no audio from amp behind glove box. took it to the dealer they tried to replace the radio but still no audio. they ordered a new amp put it in today. the dealer just called said as soon as they connected the new amp it fried. so now they are ordering a new radio and amp. he says for troubleshooting they checked all my aftermarket wiringamp under seat for sub box under back seat. he says the wiring was fine. he says they were able to get audio from the new factory stereo to speakers by bypassing the amp. he further claims that the old factory stereo would not pass audio to speakers when bypassing the amp. my question is what would cause a otherwise fine stereo to suddenly quit and fry the amp in the process my concern is maybe the issue is not originally with the stereo at all but the pci cluster tia jon in general but not in all cases when you have a factory ampd system you can not bypass the amp and get sound from the deck as the deck does not have an internal amp. think of a home stereo system where you have a pre-amp and an amp same concept. so the deck did not quit working it was most likely doing what it was suppose to but the amp was dead and unable to produce any sound. how is the amp under the set for your subs wired what was used for ground power and the audio source did you use a line out converter also have the speakers been replaced with what brand and ohm rating right off though i would say that you likely have a blown or shorted out speaker that is causing an omh load change that the factory amp can not handle causing the issue you have. if you have a blown speaker changing the deck or/and amp will not fix the problem. the reasons that the speaker would blow are simple but i will not get into all that right now. .

a good electroning supply house should have that. ----------------- thesnoman.com could some one please translate this for me do you know what a gromet is basically its a rubber doughnut that has the outer edge sliced so that the outer edge will seat against the cut area with rubber above/below and a nice protected hole through it. imagine taking a rubber hose slitting it down the center on one side only now curl the hose inside the hole with the slit going against the metal edge - it would make a nice protective barrier around the cut edges. http//www.search.com/reference/grommet yes dumbass i know what a gromit is! my statement was and you would know this if you were to read more was toward snotards post. thanks for the refreshing reply i hope you are not always so nice to people trying to help. your reply was hard to follow and didnt provide a good example or i would not have posted. -- leythos spam999f...@rrohio.com remove 999 for proper email address- hide quoted text - - show quoted text - also just look at the gps/nav thread i as like most folks am very nice and very helpful when directly answering questions.- hide quoted text - sorry right thread wrong group the one i am refering to is in the chevy group. hmmmm.. told ya buddism means yer never wrong. bfg damn! now that i write this it hit me! the idiot must practice buddismcause hes never wrong or so he thinks. gbmfg- hide quoted text - - show quoted text - lol . 222 332287 46005988.2880201000@usenet.radix.net on tue 20 mar 2007 130303 -0500 yoyo22 yoyo@yahoo.com wrote the amp under my seat is fed audio off the two front door speakers.line level power is drawn direct from battery. the ground is right at the amp through floor boards. speakers have not been replaced. risking embarrasment last week i installed a new compressor for air horns. when i reconnected the battery i got a 2 second wiff of electrical burn i thought it was my heavily overused drill and did not notice the stereo not working till the next day. i have been all over the truck trying to find the smell since it usually lingers. the only place i can smell anything is a slight hot smell from the factory head unit. im wondering if when i reconnected the battery i managed to create a surge big enough through the pci/pcm to toast the stereo which then toasted the factory amp. i have no blown fuses there are no dtcs for anything showing all my wiring checks out as checked by me and the dealer. afterwards as a precaution i did add a incandescent light in line with my compressor relay to eat up any roaming juice when the relay activates. i would not suppose simply reconnecting the battery should fry anything but now im not sure. the dealer still has my truck. they seem to be convinced the stereo toasted itself. im concerend because i play with a lot of accessories and dont relish the idea of replacing the stereo everytime i disconnect the battery. i believe i would check every place i drilled a hole on both sides of the panel drilled. it sounds like you have shorted something in the stereo system while installing the air horns. if you used wire ties you should check them as well they may be too tight causing a short. checking each speaker to ground may also shed some light on the situation. beekeep .
