I was riding in my friend's car the other day that has 2 12's and we were driving by a cop and I think he hit a button that seemed to turn the subs off so just the factory stereo was playing. I didn't think anything of it at the time but later I wondered how he did it? By the way he has a 97 camaro. Is that a special remote that he got? I am pretty dumb when it comes to car audio. Thanks guys

 

It's just a switch inline with the sub amp's remote turn on lead.
