[QUOTE="conmetal, post: 5401281, member: 605613"] I had to join to show my appreciation for this thread. I have been installing aftermarket audio for 15+ yrs, however I have never met the demon I just conquered with your help. For the most part I've been a die hard JVC man, but only because it was my first and I stuck with the line for 15yrs (upgrading every 2.5yrs). Funny that I ditched JVC thinking it was a headunit issue when it was really my Suburban's factory amp that was the culprit. Based on my needs, friends encouraged me to try Pioneers. I was skeptical due to the low end Pioneer items I remember being sold at flea markets as a kid, but I ended buying a DEH-P5000UB. I've been nothing but satisfied with it up until 2 wks ago after a trip to petsmart with my family and (2) labs. I'm not sure what happened, but one of the pups bumped the subs and the system grounded out. The funny thing was that none of the wiring was touched or tampered with. The amps wouldn't even power on at first. Thereafter, regardless of where I grounded my amps I had terrible humming and popping. I was horrified as I always took pride in my self installed systems with crispy clean audio from high to low. In addition to this, I was blowing fuses every 5 minutes. I was certain that it was a ground issue, but starting to lean towards the distortion. I checked all of my RCA's, replaced the power and grounds, including a ground strap kit, without any luck. After multiple google searches with various word combos, I found this thread. I had never had an issue such as this, so of course I would of had no idea to ground the RCA inputs to the H/U chassis. I was about ready to buy a ground loop eliminator and even break down and take it to an audio shop. I'm sure they would of charged me a full install to attempt solving the problem. I'm still shocked that it worked, because the humming was extremely loud with an occasional pop and hiss. Something so simple caused me a headache for 2 wks.
