As an amateur EE, using mass market is a braindead idea in this case.

The controller is not built to deal with high humidity which I assume is a given in this kind of sub.

Another reason is that these devices are built out of very cheap components and are not at all designed to be reliable. You can easily design a controller that is much more reliable.

Having your multi million dollar sub grounded because you allowed a cheap component on board is pretty stupid imo.
