Hi and welcome to FixYa,
Appreciate the direct "Ask Me".
Initially, the 14 seconds interval is significant. This is indicative that whatever fault it is, it is coupled to a time-based circuitry. The time-based circuitry need not be complicated. it can actually be a simple resistor/capacitor network. The capacitor takes a certain amount of time to charge and then discharge (14 seconds, 'whoomp'). Having said this, then the foremost suspect would be an electrolytic capacitor, probably low value (1~4.7uF), probably a coupler/decoupler. Of course the capacitor serving other functions could very well be the culprit as well.
Corrective measure would entail, identifying/determining which capacitor and replacement. Tedious as it may sound, each capacitor would then have to be tested for capacitance and leakage out of circuit or at least 1 leg un-soldered.
Good luck and Thank you for using FixYa.
Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate it at all. Cheers.

> I turn the volume to a low it still has the odd noise
If there is any drive to the speaker at all (volume not turned off), the rattle is probably coming from a broken 'surround;' the part that keeps the cone centered around the outer edge.
Another point of failure is a structure called a 'spider' that is located between the voice coil and cone that ensures the voice coil stays centered.
If there is hum with the volume turned completely down, the amplifier driving the speakers (internal or external) has a failing filter in the power supply.

SOURCE: Main Bass speaker not working!!
Hello Adam Hi, it looks like your main IC amplifier inside the main bass box is bad, need to replace that IC. What are your plans, do you want to do the repair or have it service by a tech guy.

Using a knige or razor blade, lift the edge of the rear sticker up. Do this evenly and you will fnd all the screws that hold it together. Take your time and you can put the sticker back down.
