I wanted the same thing you do. Keep the stock AM in the dash, but have a modern solution to music.

I left the stock radio in the dash and installed kick panel speakers, a speaker pair in an enclosure I built that sits on top of the transmission tunnel, under the dash, near the firewall, and a pair of rear speakers, and finally a 10 inch sub behind the drivers seat. All of these are hooked to a large amp mounted in the trunk.

The key to my system is Bluetooth. I use my iPhone (or iPod) to send music to a Bluetooth receiver that sends the music to the amp. So I have a "cordless" head unit that I keep in my console's cup holder during use, and out of sight inside the armrest when the car is parked.

To most people, it looks like I don't have a killer sound system, but it puts out sufficient sound pressure to be heard on the highway with the top down.

The Bluetooth receiver needs 5v for power, so I went to RadioShack and got a model 7805 solid state voltage regulator which steps the 12v down to 5v.

I love how this turned out, and the expression on people's face when they ask how my AM radio sounds so good.

 

Good combination: USA Auto 630 and Pioneer TS-A6994R 6X9. I also had my rear deck custom airbrushed with horses.

 

my current plan is to yank the stock radio, cover the hole with a radio delete plate, maybe mount some toggle switches in the plate to fill it. then mount a DIN radio in a custom console. Thats my current plan, but I have a long time before I am ready and that could change.

 

Or you could fill in the radio hole have the dash smooth there,Or if you use a vintage air kit you could get a modern style controler like http://www.dakotadigital.com/index.c...cat/cat337.htm

 

Here's my solution in my 66.
