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?

Your ports are vibrating. You need to seal them and this should fix this problem. I would use some dynomat around the outside edges of the port to prevent air leakage and to stop the vibration. You may use a bit of silicone on the outside edge of the port too for further protection from vibration and leaks. Good luck.
Sub thumps repeatedly
since it still thumps i suspect the speaker is ok, but i suspect you have an electronic problem in the amp. since it is a powered sup & has the ability to auto turn on it has electronic circuits inside, take it to a service center for an estimate
My speakers sound flat with no highs at all
I am trying to work out if you have damaged the speakers and amp too.
Have you tried a pair of headphones on the amp? If they sound ok then your amp is fine.
Assuming it is, then speakers have what's called crossover units in side each of them. This splits the sound into three parts. Bass, midrange, treble. The bass is handled by the woofer's, the midrange by a middle sized speaker or or it's combined with a tweeter, which of course handles the treble.
Connecting a 1.5 volt battery across any of the individual speakers will cause it to pop if working. If the speaker then is not getting sound then the crossover unit is to blame.
When you look at the crossover unit, it will have coils and capacitors (non polarised) on it. The bigger ones deal with the bass and the smaller ones treble. If you find a fault say on the crossover of the speaker, for example no treble comes out of it. Then start by replacing the capacitors. Use the same value as on the capacitor and remember they fit any way round.
