    Default Mobile SDA module

    Does anyone know where I can get more info on the Mobile SDA equipment that Polk had out in the late 80's?

    Also, possibly where to buy one of the modules?

    I had one about a year ago but sold it to a fellow club member. I never had it hooked up so I can't say how well it worked. It's official name was SDA ACM. It was a passive crossover network. It had ins and outs for a front stereo pair, rear dimensional pair and two subwoofers. Heavy little mother. I have never seen another one for sale or otherwise. Good luck.
