Mach 460 warranty issues . . .

[03stage2]

So i went and blew my passenger side tweeter Will ford cover this under warranty or am i once again taking the shaft?

[blue01gtconv]

im thinkin ur gonna bend over and take it again. dont think blown speakers are covered

Find out how much they are @ your local dealer. I have both of my tweeters in a bag. I'll sell them to ya for way less than they are worth. I used them for about a month before gutting out the Mach 460. I have the entire system in a bag.

This was the highest auction i could find and it didnt even have any bids. I have no ide what these things are really worth but from the looks of it, probably pretty cheap. Just PM me with what you want and i will consider it. I do appreciate the offer.

It is supposed to have a 3 year/36000 bumper to bumper warranty. So...that should include your speakers. I have to have several speakers replaced on my Dodge,(I know) but it was same kind of warranty and they did it without batting an eye. Your speakers should be covered if your still in your warranty phase.

Good Luck,
Jon

Ford should back them up, at least for the three year warranty period. Like to know how you make out. We have the same system. Wondered how much volume they would handle and how long. They should handle it all or put better speakers in.

It's usually the amp. Amplifiers will provide the correct signal to the speakers until the volume is up high enough for the amp to 'clip', that is hit it's maximum output voltage. When the amp runs at its' clipping point, a pure DC signal is seen by the speakers. The speaker likely can handle short periods of pure DC but not for very long. The DC signal heats up the thin wire in the voice coil until the wire melts. The speaker won't work after that.

It's possible to blow a speaker with too much power but over driving the amp is more common.

Ummmjmm, yeah, well, um, it broke You gotta figure a drive a conertible with 18" G-Force's. Highway driving is loud as shit and you gotta adjust the volume to compensate. You'd think they thought of that? And they said they thought of everything??? hhmmmmm .. . . .

[02roush]

As long as you haven't changed the amps, head unit or speakers, they ought to warranty it. I'd be pissed if they didn't.

I can see their excuse: "You turned it up too loud."
"Well, Ford set the volume control, not me."

Just to clarify a little.

You get "clipping" from digital. "Overmodulated" from analog. The 460 is analog.

Basically, there is headroom in analog. If you push analog too hard, it still plays, but starts distorting(signal-to-noise). If you overdrive digital, since its all 1 and 0 's, then it can't convert the analog noise into the 1 and 0 's, so it clips it. Basically, you feed it too much info to convert.

I've been learning a lot more about digital lately since my work has been transitioning to digital. Our audio console is digital. Unlike an old analog mixer, where if you "pushed the needles too hard", it distorted some. If you push the digital too hard, it just crackles and if you keep pushing it harder, eventually all the sound will disappear, replaced with digital clipping.

02roush is right, if you blew a factory system speaker, the amp was the weak link, not the speaker necessarily.

Something I thought was strage until it was explained to me is that a speaker recieving too much power will actually last longer than a speaker receiving a distorted signal that isn't even at the speaker's max RMS rating. One of the main reasons is because the motion of the cone actually helps to cool the voice coil, and as 02roush pointed out, a "constant" signal causes stops the motion of the cone because it gets a sustained signal, which is heating the voice coil, but not moving it to cool it.

Also, distortion produces a relatively unpredictable movement for the cone, which is rough on it mechanically, as opposed to a powerful yet controlled signal that can accurately move the cone the way it is supposed to, in a comparitevly smoother motion.

There are a bunch of other factors that was explained to my buddy by JL engineers doing the demonstration in his shop, but those were the highlights that I remember.

This is why you can blow a speaker rated at 160watts max on a factory head unit, because of distortion, not too much power for the speaker to handle.

Actually it's the other way around if we're using the same terms. Your mixing panel is digital, before the digital-to-analog converters. If you overdrive the input to the D-A converter, it can't track the signal and you'll lose the analog output.

Clipping occurs in the analog domain. Apply a single frequency to the input of an amplifer and you'll get a sine wave but at a larger voltage swing at the output (ie it's been amplified). Apply too large of a signal to the amp input and the amp gets overloaded, the output voltage hits it's maximum and stays there even thought the input signal is telling it to drive more. On a scope, clipping looks like a sine wave with a flattened top.

I had a problem with my 6 disc changer, just had to get it to do it for the dealer and they ordered me the part and replaced it. should be the same thing, i would think.

[03stage2]

Yeah my 6 disc is f'n up constantly. Ill hit eject and it will just sit there with the tray open and wont eject. The it gives me an error and only lets me listen to the radio. I have to disconnect power to reset it, then jam in another CD just to get the old one out. . . Getting irritating!!

i blew mine or so i thought, i took it to circut city and they fixed it somehow

could have blown a channel fuse on the amp itself if it has channel fuses (not familiar with the mach amp... yet... but it should and probably does) and they just replaced that... just a guess.
