Forget Dean's good advice.

Turn your speakers around and point them at his wall. Next time he's arguing loudly with his wife, play the shoot-out scene from HEAT at top volume. Then call the PD and report domestic abuse coming from next door. Also file a noise complaint.

If that guy is going to call the cops before whatever time the noise ordinance goes into effect, call the cops every time you hear them fighting. Tell them "well, I guess I'm just calling about how loud they're being, but I'm also a little concerned about his wife's safety, this happens a lot." Officially, you're just reporting the noise. Unofficially, homeboy is gonna get the cops up his ass.
