What's the difference between all of DEI's brands?

They're really worse than GM. They have 7 brands for Audio and NINE for security. Are some better than others? I know Viper and Clifford and pretty good brands, but how do the rest of them stack up? How do their audio brands rank compared to more mainstream brands, like Alpine, JL, or Eclipse?

Honestly, from my understanding it's price, that's the only difference. Obviously the features are going to be more limited on the cheaper brands, and more extensive on the more expensive ones. But, that has less to do with brand and more to do with price. However, most of the more expensive brands (clifford, viper etc) have better remote range.

According to DEI certified technitions and installers, there is no other difference. I have worked with and consider these installers friends, and would stand by their word. If they say one DEI is the same as the next, it is.

yep they're the same..

Their speakers are sick... they all handle 50w RMS or more.
