Ok..here you go..i have been installing audio professionally for years..and have seen this problem more times than i can count. The reasons behind engine noise/whine can sometimes be cured..and sometimes not. There are a number of factors that can attribute to what is happening..first off..3.5" and 4x10's are NOT MADE TO PLAY BASS!!--if you try to they will sound like shit no matter how low it is..if your stereo has crossovers then use em..(filters in the options menu)IF you want bass..get a sub. Since you say it is crackling and popping this is my assumption. If there is a whine of any sort..or if you are still having problems..then it can be attributed to a poor ground on the stereo, the TYPE of plugs you run in your engine..some platinum and splitfire plugs will definetly do this..(varies by car) Most common for this problem is a looped ground..the stereo and speakers are not seeing the same ground and therefore picking up signal from the engine. sometimes the wiring for the speakers cannot be near a main wiring harness with lots of power wires (I.E.--fusebox) so even though you ran new wires..it can still cause the problem. There are just those cars that cannot be solved easily..some are stubborn and can't be cured..the fix for that is to move up to a 4 channel amp for your speakers..it isolates the signal from the amp, and creates a stronger ground..(but dont run your rca jacks near a power harness either..run it on the opposite side of the car as the power wire for the amp. do not hook a ground wire from the stereo to the speaker unless it is the speaker lead only. the speakers read a certain ohm load than the ground wire..But my first thought is still with the bass..get rid of it and move up to a sub..those cars weren't designed to play the boom boom.....good luck.let me know if you have any other questions if these do not work.
