hope this is the best place to post this.

over the years I have found/accumulated a good deal of Old school (A/d/s, PPI, Zapco/MSI/Adcom) car amps.

wanted to fabricate a way to test them outside my car.
Can someone give me a step by step on how to build something which would allow me to test car amps?

I found a 12volt AC to DC unit today which I was thinking of trying, but I assume an actual car battery would be best??

I only want to test amps and can use an external home CD player (as the source) with a variable output volume control which I assume I can hook directly to the RCA inputs to the amp?

In my old shop I had a shop radio under my bench which i tagged a hilevel converter on, so id have rca signal, then I had a 55 amp 12 volt power supply and then I had a test speaker. nice and simple but worked easy and fast.

easiest way:
1.) car battery
2.) ipod or phone with music capability, hell anything with a headphone jack.
3.) mini to rca cord or adapter
4.) speaker

make sure you hook the remote on the amp to the + of the battery as well, you can even jump from the + of the amp to the remote.
