Hey guys, you need to at least check out the 'Black Box' panel from Enos Custom Components, first cabin quality and only $150.
I got to know these guys from our big Jan. swap meet some years ago. What really impressed me is that they custom design each panel/kit to the customer's vehicle. They had me fill out this complete questionare about my car, then the system arrived with pages of drawings and instructions just for my installation. Also they keep a file of their panels and customers so when you call with a question they can pull up your file and know exactly what's involved with your system. Check them out.
