You know what the worst part is? If you took that head unit back to the place you bought it, explained the situation, they wouldn't even consider replacing it.

They'd say that's not possible for you to detect that, or they stick it on their O-scope and see nothing (if they even have one). Just try to convince them that the DD-1 was made by some of the top guys in the industry, but they won't give a shit.

And then you'd be out $1300 on that brand new head unit.

Thats when you call them noobs for using an o-scope to detect distortion. You use a distortion meter to detect distortion.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.

Great video!

Spreading the word out in Colorado on some facebook pages to hopefully convince some haters. We'll see.

:good:

This shouldn't be taken as a dig on Alpine at all. Any consumer electronics company that produces equipment in the thousands to millions is going to see some component failures.

Its just a given when things are produced at that level.

This is a prefect example though of the true capabilities of the DD-1 vs an Oscope. Sometimes you can't always "see" the problem whereas a specified device that hunts for distortion comes in real handy!

I had a similar situation with a buddy of mine. He went and strapped his amps and said he didnt believe in the dd-1. well summer goes by and he blew his very expensive subs, so i said lets check your gain with the dd-1. well as it turned out his amps had an issue when strapped that caused distortion 100% of the time even with the HU off and amps on.

If he would have let me set his gains we would have found the issue before he lost $1200 in subs lol

Guys, distortion isnt clipping. Its just a difference in the audio signal to what was intended. Distortion could blow your stuff if it flattened out the sine wave to square blocks or something, but its not very likely..
