Speedbump, then out cold-Sub or Amp prbm?

all nissans have the crappy ground,, you definately need to ground some metal that connects to the chassis.2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

First off, I just want to say thank you to all who have taken time to give ideas. We all have better things to do, and this is just super, I am lucky to have found this and the Xterra club, and the MacNN, etc. OK---so my guy blew me off, and I had to do this myself, but I remember watching him install it, and it's really easy. The 4x4 Shifter is the only thing that makes it a pain in the ass (we can swear here, right?)- Anyway, I took the dash apart and the head unit screws off the mount, and pulled it out. The g****** thing didn't go out once while I had it on the passenger seat!!! Nothing wrong. So, I tried to yank, and twist, and anything I could to simulate the episode, and nothing. It wasn't until I got it back in the chassis (right term?) in the dash that it went out! If I was Jewish, I could think of a few words to shout. But I guess I'm relieved to know that it has to be a wiring thing like y'all said, and not the receiver. God, what a sweet sound-processor and interface and everything else about the Kenwood is just magnifique.    To sum this up, I did notice the black ground from the HU connected to the stock wires, and strangely enough, it actually breaks off into two seperate harnesses! I pulled and they're tight as can be. I repeated the action of placing the HU back in, and it went out like clockwork again. So, I remembered the recent installation of the (get this) 6 meter Keg cable (Keg is a PhatBox with Kenwood name on it) which is crammed in with all the other wires. All the wiring behind the dash is enormous, and must be the culprit. So I pulled it all out and placed it back in again. So far, so good. Drives me crazy to think which one it could have been, but I think if it happens again, I'll snip the ground, and wrap it around one of the screws like you say. That's it, and if anyone wants to elaborate on the crappy ground issue, it may be interesting. Thank you again... -matt"Find a profession you love, and you'll never have to work another day in your life."

PSS - The crossovers no longer light up, is that a good thing? And does a more stable ground kill the distortion that was occuring?"Find a profession you love, and you'll never have to work another day in your life."

y would the sub being turned on cut the deck out is wut im trying to figure??

This is what I've summed up. Every time I say "everything's great now" I get burned, and Murphy's Law comes back to haunt me. Chicago still is an Irish run town. I can only assume that the ground solidity was the reason. I did nothing except jiggle the wires and tug & yank. Finally it seems to be grounded correctly. If the above mentioning of Nissan's shortcoming is true, than that must be the case. Maybe the Sub caused enough "sub-sonic" vibration that broke the connection for just a split-second long enough to trigger the shutdown. Maybe the HU itself is protected from surges and connection screw-ups??? Who knows. Like I said, if it happens again, I'll take it to a pro-shop and have the whole dash rewired.
