engine noise coming through speakers

If you performed the test at the top of the page and found that the shield of the RCA jack did not show continuity to the chassis of the radio, then yes it will get rid of your noise.  You really only need to do one of the cables.  If you do not have a meter, ground a wire to the chassis of the radio or to the radio's ground wire, then touch and hold the other end of that wire to the shield of the patch cord to see if it makes a pop then the noise goes away.  If it does, then solder the wire as shown.

You mentioned that the popping noise is coming from the tweeters. Did you make sure that you have a good connection on your crossovers? Popping through the tweeters is commonly caused by the connections on the crossover not being tight.

yes all connections on the crossovers are tight, i even re did them just to make sure and it didn't eliminate anything :(

i am an idiot- i did exactly as the webpage that you posted said, and it did not get rid of anything, noise is still coming through all speakers, do you have any other suggestions?

Have you tried turning the amplifier's gain adjustment all the way down?

noise started to go away when the gain was turned down, but in the end this doesn't solve any problems does it? because gain should be set at a comfortable setting throughout the car. if the gain is down, in order to eliminate the clicking/popping noise then, problem still exists. on an amplifier is there supposed to be 4 or 8 gauge ground wire/power wire?

It will change per amplifier. It depends on how big the inputs are for the amplifier honestly. If it accepts a 4 gauge, then use a 4-gauge if you have it readily available. You can never go wrong having a bigger ground than the power, but never have a smaller ground than the power. It needs to be equal or bigger.

Turn the gain down to the point in which you can no longer hear the noise.  Turn the radio volum up, can you still reach your desired listening level? 

gained was turned down and the clicking/popping noise went away, but it is still there at a very low volume, so this problem can only be resolved by reworking the ground in the car? do you recommend i have 4 gauge ground cable at the battery terminal to match the 4 gauge ground at the amplifier? i also have another mono-block amplifier in the car that's connected to a subwoofer.

Would having a cheap amp kit contribute to having popping noise through speakers?
