I don't understand

But, your definitely thinking it is something inside the amp?

just saying its possible ,its a process of elimination , rule out all possibilities

I really hope it's just some loose ground or a bad rca cable.

Also, is there a possibility that the sub has a problem? Or that's caused only be the signal sent to the sub?

caused by the signal or the amp

I will check on that.

Thank you very much, I appreciate all your help. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

Well, to be honest, that connection stayed there from when I had the stock radio.

Gotcha. Does the noise go away if you don't do anything to stop it, or have you not tried that yet?

We have a natural tendency to try and fix annoying things and I've seen it (and it's happened to me) where a person will think they're "fixing" the problem by turning a knob or tapping something, etc, when in reality the problem is just going away coincidentally to their action.

Yes, it does go away without me doing anything to stop it.

meaning it goes away even when you do not turn it up?

step one. un plug your rca wires from the amp. see if this weird rumbly thing happens still.

with no imput signal from rca wires a good amp will produce no sounds to the sub / speakers.

next - try replacing or adding an additional ground wire from your amp.

have you done the big 3 yet ? if not you will benefit greatly from the addition of this ( its in a sticky somewhere how to )

sometimes ground conection can get loose or build up corrosion over time and become poor at transfering electrical energy.

check all grounds - take them apart and clean them to shiny metal and re attach firmly

bad ground

You might try making it happen by manipulating the RCA cables where they enter the amp and possibly, the head unit.

My ground wire pin in the connector on back of my hu was getting loose and it did the exact same thing.Not saying this is the problem,check all grounds an rcas

Had a similar problem once that was caused by me using two rca cables joined together. The metal chassis of female/female connector was touching the vehicle chassis and inducing noise. Wrapped the connection in electrical tape and it was fixed. Just food for thought.
