what up folks,i need some advise regarding,why i can hear the engine through my subs,it wasn't doing after i change my box to a bigger box,i did a couple of things check the rca,took the rca's off the amp and it stops,so i went out and bought a new pair of rca's,took the new ones plug them on the amp and my deck,not right next to the power line and it was still doing it,then i tried putting my ground in different spots and i also put on the negative side of the battery,and it was still doing it.there isn't really much i can do because i dont have tools to check the rca's if its working right,if there someone out there that had this problem before, i greatly appreciate it if you guys can help.

Only thin I can think of is run your RCA on the opposite side of the car from all of your other wires and keep you RCA away from the fire wall, also tr adjusting your pre out voltage on your amp and make sure it is within H/U specs
