Your problem sounds like either a bad ground or either a bad RCA cable.
I would disconnect your battery and clean all your grounds and make sure they all below .2 ohms resistance.
If you still have the noise then try replace your RCA cables and keep them away from power wires
I would also recommend doing the big 3.
Good luck

Alternator whine originates from poorly rectified Alternating Current from your alternator (thus the reason it is called an "alternator"). Before alternators they had generator that provided DC [Direct Current].
If the AC from your alternator was being properly rectified and filtered it would be nearly impossible for "alternator whine" to happen in the first place. Although alternator whine can also be generated by they ignition system (distributor, ignition coil, spark plug wires). All these devices are capable of generating annoying radio frequency (RF) waves.
Anyway, your choke [a capacitor]; attached to your distributor may no longer be working. If your car has a distributor (you did not specify what kind of car you have) try getting a new choke but before you do that and check the connections on your old one.
You did not specify what type of noise suppressor you bought since there are several types. The type I always used to use should be installed between the battery and all the other stereo/media accessories.
They are just sealed boxes but inside I am sure you would find resonant circuits that supress the most common frequencies that are associated with "alternator whine".
Buy some wire brushes or wire wheels if you have a drill and clean your grounds to the best of your ability. Buy some spark plug wires that "reject" alternator whine.
Most of all, start off buy doing the least expensive things first. Cleaning contacts and checking all your contacts to make sure they are secure is cheap. I am not just talking about your stereo either. All connections associated with your charging system and ignition system too.

You could have many issues: Overall battery age and condition, which also applies to altenator, spark plugs, etc. etc.
The overall condition of the ground for the system can also be a factor. Wiring and where you run them can also be an issue.
In other words, there is no easy answer to your question.
If you installed an amp, try running a ground all the way to the battery to see if there are any improvements.

you are hearing the squeeking noise through your speakers because the power is surging and your amp is draing too much power. it is not doing your amp or car any damage but the only way to stop the squeeking is to wire in a power cap into the positive wiring

usually when i hear problems like this, i think of rca cables. i once had a nice setup and had some noise problems like you have descibed. so what i did was go out and buy a 50 dollar pair of zero noise interconnect 2.0 wires. i had no more problems with noise after that.

Is it alternator or interference from the plug wires? Is the ignition shielded?

Add another ground to your radio,then get thicker speaker wires.

check where you ran your rca cables run them on the opposite sid of you car form the power cable that goes to your amp
