OK I want to install a sub+amp with my standard astra head unit.
It's this standard delco unit; http://www.gumtree.com/posting_image...b3.__big__.jpg
Is there a how to guide?
How do I remove the standard unit?
I've been told I need a red/white converter connector because the unit does not have it?
How do I take the interior up to hide the wires?
Anything else I need to know tell me!
