audio shop exhibit display

hi, im trying to build a audio display for a friends shop , but i cant seem to find any ready available products or comercial versions to take ideas from , im planing in displaying 12 head units ,10 pairs of voice speakers ,4 amps , and 4 pars of subs, i need to have the ability to switch between all of them so custumers can hear the diference ,i have many ideas but i want to see if anyone has first hand experience ,diagrams or info, my plans are to use a serial 32 I/O board and a computer with a touch screen monitor with the display layout on the screen and a flash front end to interect with the I/O board and do the switching , but maybe someone has done it more easily or has diferent ideas ,any info or input is welcome.

I have a Winntech Scorpion for sell if interested. Comes with switching and power supplies. It will switch video, audio, amps and speakers. Price is $5000.1 Day older than dirt and still installing!

There's a company in Johnson City, TN called "Ride Revolution" they have by far one of the best shop set up that I have ever seen in this world. Unfortunately they are going out of business they are selling all of there displays you can go on there web site www.riderevolution.com on the top right of the page you can see where it says " our Facility" click on that and you can see pictures of there shop and displays. One picture is of there drag car that matt scanton drives for the nopi drag racing series. hope this gives you a idea of a display If You Can Imagine It Glass It!

Blow your budget out of the water so you can sell that nice disply to me cheap. Start out small and grow big your wallet will understand...
