1723 Subwoofers – Why Does the Amp Plate Get Hot?
The amplifier plate will go up to a certain temperature because the entire front plate of the amp acts like a heat sink for the internal transistors. We recommend not covering the plate with anything to let the heat dissipate, and it will never be so hot that it is uncomfortable to the touch.
This does not apply to legacy subwoofers, only the new 1S, 1V, 2S and 2V models.
