Is there ANY way to have the Systems 9000 or Astro Siren amps operate w/o the radio? I've got several more amps with cables & deks than I have compatable radios.... I haven't turned up any site links with information/pin-outs etc. to do this. Has anyone succesfuly done this? As always, Any Help Would Be Much Appreciated!
Thanks,
Kyle
