Change out Bass but still intermittent and got earthing noise regularly!!!

Hope you are all enjoying the festive season!! Got a scenario to ask advice about.......so here goes......

I had no sound coming from bass speakers in my doors, so I replaced them with OEM as I was also getting a ground earthing crackling sound when going over a bump and opening the car drivers or passenger doors - car is LHD. It's driving me mad as a garage I use had a look and worked on the Kessy unit but its still failing to make my speakers work properly and I get bass now and again, but lots of crackling through the stereo like a ground earthing problem!!

Not sure what to do now!!! Replace the wiring, Kessy, amp or what??????

Planning to try and remove the AMP tomorrow...... anyone got any good instructions as can't find anything in the forum on a search. Maybe try youtube tonight and see what gives.

I drove really quick up a hill and the weird thing is the speakers came alive then when I slowed down and braked its like shunting it forward dislodged it they went off again!! Thats not the first time that happened so must be something. Driving me mad as I want to hear the tunes with a bit of bass!!

So.....I got the head unit out today.......... nada......

All cabling removed and reseated. Seems good and intact, so its not the back of the head unit. and took some pics also. Was a bit of a PITA as had to remove centre console and then the trim round the head unit, but was just under a bit of pressure as missus was at the hair dressers and I only had 90mins and was first time removing everything, but have some good interior removal stuff as done a few head units etc over the years so know what I am looking at mostly. Tomorrow will remove the house battery and amp and get a better look at that side. Other than it being internal to the amp I am not sure where to head to next.

The weird thing is, under hard acceleration and always up a hill bizarrely into 80-90kmph, both the speakers at the front of the door that are off, kick in full blast and I get BASS!! And as soon as I stop kicking the **** out the speed they go back off!! It's like they get insides of the car get shoved back and they kick in!! So ****ing frustrating! I wondered if it was a crossover problem with cabling. It's deffo a cabling problem I think.

Anyone else had anything similar?

So got to the bottom if it!!!

The garage has obviously thought by changing one speaker and everything coming alive it was all fixed. When in fact probably maybe only hours after it that the 2nd front speaker has become separated from the housing and was causing the intermittent barking again!!
