I need to deinstall my empeg mkII from my Mazda MX-5 pretty quickly - I'm selling it next Saturday and need to get the empeg out before I take the Mazda around to a local car audio place and have a cheap CD player put in. The question is...

Is there an easy guide available to removing an empeg installation? It was done by Cambridge Car Audio so there shouldn't be anything funny/unusual about it. I'm not worried about speakers, subwoofer etc - just that the head unit/sledge and cables all be intact.
