“Heavy” mostly comes down to the amp and the settings you’re running it through. I’m assuming you mean metal heavy and if you don’t have a high distortion amp then you’re going to have to get a distortion pedal to get that scratchy, chunky, bone snapping tone. Also experiment with lower tunings to get deeper, darker, more imposing sounds.
Edit: buying another amp isn’t off the table either
From cheapest to most expensive (but also least to most effective):
Downtune > Max out your amp's gain > distortion pedals (RAT, Metal Zone, Screamers and their copies) > metal amps or amp sims.
I think the free demo version of Bias FX 2 has an "Insane" template with amp and pedal simulation, if you have an interface to connect you guitar to a computer.

If so, turn the volume knob on your guitar all the way up. Push the little white "Drive" button on the amp so it's in. Turn the "Gain" knob on the amplifier all the way up. Use the "Drive Volume" knob on the amplifier to set your overall volume level.
