I've noticed that my Epik Knight subwoofer does not have the slam that it use to have. I remove the amplifier and noticed a huge glob of a glue-like substance around the exterior of one the capacitors and the transformer. Could this be the reason behind the lackluster performance of my sub? I've seen many amps and have never seen globs of this glue-like substance before. Any comments or suggestions are welcomed.

Sometimes glue is used to mechanically hold components in place so that they aren't completely reliant on the solder joints.
I'd take a picture and email it to epik.

The glue isn't in the area of the solder joints. It is on the sides of the capacitors and on the top of the transformer.

I have seen that before on some sub plate amps. I believe it is used to prevent components on the boards from vibrating from the excessive low freq SPL inside the cabinet, and as a way to ensure connections don't rattle loose. Does it look like this:  C |

Subwoofer amps often have 'goo' surrounding the components to prevent the vibrations from the sub from damaging the circuit. It can be a real pain if you have to replace a cap or something. I doubt it's affecting the performance.
