Thanks for the response. I thought it was a problem with rca's so I put a new set on. When it still did the same thing I thought it might be the amp so I changed that. When it still did the same thing I thought my cd player was sending bad signal so I changed that. Now I'm at a total loss unless I messed up both cd players or amps somehow or maybe there's a short in the wiring on my cd player making it send bad signal.Thanks for the response.

That's it! My step dad came over and we tried grounding the high input on the amp with a ground speaker wire from the head unit. It stopped right away. Then we put a meter on the case of the deck and the outside of the rca out put. It is not grounded. Its a pioneer super tuner 3d. Is it supposed to be grounded or dose it rely on the rca inputs on the amp for a ground? Thanks for all your help.That's it!

The RCA shield of the head unit should be connected to the case of the head unit (internally). Pioneer head units have a fuse to protect against fire if the shield of the RCAs comes in contact with a power source (that's likely what happened in your case). If you use the temporary fix, insert fuses as shown. Do not make a direct connection. It could be a fire hazard.

The shield on the RCA jack may have broken loose and needs to be resoldered. The shield on the RCA jack may have broken loose and needs to be resoldered.

If the lights on your sub box aren't coming on it's either your ground of power wire came loose or the transformer blew. As for the subs, make sure all the connections are good, especially on your RCA wires. If your amp is getting power, then check your speaker connections. Also, make sure to turn the gain know up. The gain knob is located next to the RCA input on the amp. Let me know if this helps.
It sounds like it has bad ground on the RCA input assembly, you should Ohm out the ground of the RCA jacks to see if they are all connected.
How about the sender side (the amplifier) ground?
Many times a "humming"sound is caused by bad signal, caused by things like, bad rca cable, bad rca ground from the radio, or even a bad ground in from the amp to the car.. Wiggle your rca cables at the input to the amp, and see if it changes the hum at all.. If not take a short peice of speaker wire, and wrap one side arrounf the outside metal at the end fo the RCA jack, and then touch the other end to ground, and see if that makes the humm go away. If the humm goes away at that point then you need to have your radio replaced, or repaired. if neither of these do anything to the hum then check for tight ground connection to the amp, and to the car..
There could also be a problem with the amp it's self, but this kind of thing is hard to diagnose over the web, so try those things, and let me know what happens..
I believe you have a wire touching a ground somewhere in your car stereo circuit. Most likely there is a speaker wire in your dash that is the cause. Here is a reference: http://www.bcae1.com/brighead.htm
Also make sure the RCA's are taped up in your dash, they will create an entrance to feedback from the amp, which will inturn make your subs go crazy. Also, unplug each channel RCA from your amp and see if it stops, you may have a break in your RCA's causing a ground.
try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.
You have a Direct Short in the System Between the Head Unit and the Amp. Check the Ground on the Amp and then Check all the Wires behind the Stereo and the Common Ground There. You could even have a Spot in the New RCA Cables that is Touching Metal Somewhere. Please Rate My Response! Thanks!
He may be right! You might try finding a new source of contact for your ground cause it may not be sufficent enough to ground to, also make sure that no wires from the back of your radio have any wires sticking out touching other interfering things that could possibly be causing the noise
first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
cheers

No just when I unplug them completely.

I'll give it a shot. Thanks again for your help.

Test the shields on your head unit.

If you push the RCA plugs up/down/to the side where they plug into the amp, does the noise ever go away or change?
