I just got 2 12 inch sony xplods (I know there not great but I got them for 20 bucks) I dont have a amp yet, but I wired them to my 6X9's and they worked, but when I turned off the 6X9's the Subs were making more high pitched noise than low pitched noise, is thier anyway I could keep the the wiring almost the same, and have the sub play lower sounds, with the 6x9's playin more higher pitched. ANY HELP COULD BE USED. PLEASE HELP!!!!!!!!!!!
