Will the PAC Audio AOEM-GM1416 amp interface work on a 2010 Silverado (non bose)? The listing is for a 2009, but I'm hoping they are the same. I want to add an amp and 1 12" sub under the rear seat of my crew cab but I want to keep the factory head unit. (has bluetooth etc...) This interface would do the trick. I tried searching, but only found older models with the Pac audio. On a side note, anyone make a single 12" enclosure with any cubic footage? About .80 seems to be the norm. Maybe I'll make one. Thanks!
