This is probably a duh question. I'll be getting the Scosche LS2080B double DIN to put new audio in the ES, however I'll only be putting an Alpine single DIN in. This will work, yes?
And since this won't be a p&p deal, I'll be paying Best Buy so they can worry about it.

 

It looks as if it's made for double-DIN applications, although many times the kit includes a panel for half-DIN application (the panel's not mentioned on the manufacturer's product description page, however).

there are single din kits out there... i had one in my car but it was custom made for a double untill i got the scosch one
