I bought new equipment which includes a 15 inch alpine type r and a 1000.1 hifonics amp. I have a AVH4200dvd pioneer head unit that my dad gave me. He found it in a truck he bought. Now that I have everything hooked up, I can hear static coming from the speakers even when the volume is at 0 and the car is off. I checked the ground for the amp and it's fine. RCA's are not near the power wire leading to the amp. When I turn the gain down I notice that it goes away but then my speakers don't sound loud enough. Is it the gain being up to high or is it another problem? Any help would be much appreciated as I am worried this is turning into a money pit.
