Installation problem need help!!!!!!!

[big beeza]

i have 2 memphis pr 12s and a memphis pr 500 watt mono class d amp. i have the the subs wired to 1ohm, and when i cut the volume all the way down to 0 the subs still hit constantly non stop no matter what until the cd player is cut off. i went to a car audio repair place and they said is was the cd player doing it. i disconnected the rca cables and it still does it. has anyone else ran into this?

Turn the gains down a bit on the amp and change where you have the amp grounded at

if the subs are buzzing with out the rca's connected to the head unit, you have a ground loop.
