New stereo wigging out

[mrmel2you]

Having issues with a new stereo install I put in over the weekend. I put in a new JVC unit (AM/FM/CD) has Pandora, IHeart and is sat' ready. Installed new rear speakers and dash speakers, new wiring also (speakers and head unit). My issue is this; when listening to the radio--the speakers sound like they are shorting out, lot of static sounds. But, when listening to anything that I plug into it--phone, MP3 player, SD card, USB stick---they all sound awesome through the speakers. I checked and cleaned all the connections, ran all new ground and supply wires, checked the polarity on all speaker wires, everthing is as it should be. I'm at a loss on this one. Anyone have any other ideas?

 

Many many thanks to all in advance, Papa Mel

 

Happy Trails everyone :)

if it is playing good when you plug something in or playing a cd then you looking at the unit it self, or maybe you have a bad connection with your antenna. If your antenna connection is loose some where it could cut in and out. The other thing is on am/fm you could be picking up some waves that are causing static. My best bet would be check you antenna, and make sure it is not grounded to the body, or got loose / corroded connections

I was thinking the same thing, the antenna.  The original AM/FM radio was doing the same thing, so I replaced the antenna and cable---no effect whatsoever.  That prompted me to replace everything; radio, speakers, wiring etc...  Really want to get this sorted out so I can actually enjoy driving my MJ, after fixing everything else (steering column, rebuilding the head, fixing the exhaust, shocks etc...).
