You can either leave the receiver sub trim at its minimum and do your fine tuning using the sub volume control, or get/make a passive attenuator to go between your receiver and sub. Crossover distortion is a type of distortion which is caused by switching between devices driving a load. It is most commonly seen in complementary, or "push-pull", Class-B amplifier stages, although it is occasionally seen in other types of circuits as well. The term crossover signifies the "crossing over" of the … See more The image shows a typical class-B emitter-follower complementary output stage. Under no signal conditions, the output is exactly midway between the supplies (i.e., at 0 V). When this is the case, the base-emitter bias of both … See more • Electronic amplifier See more As with most kinds of distortion, another way in which crossover distortion can be reduced is through the use of feedback.

"WebMar 10, 2016 · The 1-Watt THD+N measurements demonstrate that the AHB2 is free from any crossover distortion. Note that the AHB2 also stays clean at 1/3 power and at its full rated output power. Also note that there is almost no measurable difference between 8-Ohm and 4-Ohm loading. The same holds true for bridged-mono operation. " - Crossover distortion.gif

So my advice is to install the pot (but first measure the idle currents at the factory bias setting, so you can go back to the stock tone), and then adjust the bias so that the hotter running of the two pairs of output tubes is not running too hot (don't go much over 40ma per tube.)
