Ferrari Engine Noise

Thanks Dan, that's what I was going to look at first tomorrow.There is no such thing as free installation!

Considering that the frame and most of the body is aluminum, that wouldn't make any difference.It was already broken, but I made sure it could never be fixed again.

Sounds like you're getting it down to two options: bad amp or electrical noise from the ingnition system.  Any chance the car's not using supressor wire for spark?  Cracked distributor cap or plug?  Bruised wiring somewhere?  You might have to add an old-school filter on the coil output... Sounds like time to pop that hatchback and get into the engine...Support the12volt.com

And we thought we were done 10 days before our deadline! Now we find out the car has been in a wreck. The install Gods are punishing us for something. Dumb Dog.There is no such thing as free installation!

Well, look at it this way: If the wreck was BAD enough, you don't have to worry about the noise any more! BWAHAHAHAIt all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

OK in 30 years I've never run acrossed this. Yesterday when we removed the RCAs the noise was still there, however since the sub box isn't ready yet we left the sub RCAs hooked up. Today when we pulled out all the RCAs the noise went away. So I made a set of RCAs where I isolated the shield grounds. When I grounded the deck side the noise went away. When I grounded the amp side the noise got worse. When I connected the shields (as a normal RCA would be) the noise went away and no I'm not touching the wires and using myself as a ground. So here's the best part, when I make the noise go away, and it is completely gone,if I move the volume control on the deck to zero some noise comes back. If I move it to 1, it's completely gone again. I'm going to try another deck. God I want to retire.There is no such thing as free installation!

No Ham, the car's been in my shop the whole time. We found some welds in the door that were definately NOT factory. It was in a wreck before it got here. Think this might have screwed up the car's ground?There is no such thing as free installation!

The closest thing to a ferrari that I have worked on was an mr2 with a ferrari body kit, so I can't say for sure, but if you can't get it figured out just blame it on the body shop that did the repair work. It works for the stealerships, so why not for us common folk?

That's great.It was already broken, but I made sure it could never be fixed again.

An MR2 with a Ferrari Body Kit??? Cool. I think I saw one in a dumpster at Planned Parenthood.It was already broken, but I made sure it could never be fixed again.
