what's up with .......
 

Sounddomain/ Cardomain, did they go outta business?

What do you mean?
The site still loads.

I just tried navigating.

Although the site technically works, its useless since I can't get to any actual products or buy anything.

They even took away the shop tab, you can't order products from the site???

There's a page that says "Coming in November: An Exciting New Parts and Accessories Store from CarDomain!". I guess they're just revamping the site.

I just noticed their Support page:
http://www.cardomain.com/features/support
(There is a link to it on the main page.)

Looks like they probably won't be selling car audio stuff any more. Which is a bummer since they were just like Crutchfield but cheaper.

Yes they are closed.
