Help Identify a Sound System Problem Options

[Chovies]

So i will start by saying i have no idea what im talking about so what i describe now is about the extent of my knowledge

During the last month while playing music i would get a really loud pop/bang which sounded like it was coming from the left side of the car, slowly i had to turn the music down to avoid the popping and now im sitting on 8 when my normal volume is 20 and i still get this popping sound, its always random and is almost always when im driving/ cornering/ bumps in the road. I just had my car parked in the driveway pumping out 20+ and i couldn't get one pop.

The guy who owned it before me was really dodgy in his work and Ive noticed that the wiring is wrong in the amp ( front in (L) seems to control the sub while both the rear in inputs do nothing ) so im not sure if its dodgy wiring or my sub has blown or a bad earth or....anything...

I don't really want to spend my money on buying both a new amp and sub so if its something simple i can at least try then i may be able to buy one or the other.

What's your setup? Stock or aftermarket head unit and speakers? Is the popping from both the front and rear left speakers?

The possibility that immediately comes to my mind is that there is a loose connection or short on one of the wires between the speaker and the amp or stereo.

The proper way to join wires on a car is to solder them together and then heatshrink them, but only a very small percentage of people go to the trouble. Most amateurs who intall a stereo do a really shoddy job, poor crimps joining wires and Ive even seen screw cap connectors or no connection at all, the wires are just twisted together and may or may not be taped/insulated.
If you can access the wiring behind the unit(stereo, amp and speaker), I would suggest poking around through the wiring with the equipment running. When you hear the popping due to your prodding, you have located the short/open circuit.

Let us know if this helps

Definite shorting connection.

Check all wires for loose joints. As Edy said, solder them!
