SPL Cartel: Modified Cars & Massive Bass

Perth’s Loudest Cars Go Head-to-Head

In this episode of BAD Q Garage, we head to Welshpool, WA, for the SPL Cartel 3 Song Challenge, where competitors battle it out to see who has the loudest car audio system.

The format is simple—play three songs, average the dB readings, and the loudest setup wins.

From daily drivers to dedicated SPL competition cars, the event was packed with huge subwoofers, powerful amplifiers and serious bass.

More than just a competition, SPL Cartel has built a strong community of car audio enthusiasts who share a passion for loud, well-built sound systems.

A huge thanks to Jason and the SPL Cartel crew for having us along. If you love car audio, big bass and custom builds, be sure to watch the full video.
