Depends if you attract attention or not. If you go thumping, likelihood of attracting wrong attention becomes greater. And posting on social media won’t help as then you become a potential target. Thieves can narrow down your location by state or city and scope you out.
Had a bad experience back in the 90s. Luckily it was a beginner’s audio system with cheap components that got stolen. For my SQ build a couple of years later, I threw in every conceivable auto security feature available: Alpine 8080 alarm with pager, proximity and glass break sensors, battery back up siren tucked inside wheel well, hood lock, piezo pain generator sirens inside the passenger compartment, Clifford BlackJax anti-carjacking device. Only thing I didn’t get was LoJack gps tracker. IMHO when you go high end audio, you need to spend more to protect it. 2 cents.
