Customer cars that prove the system.
These are real vehicles with real systems — designed to a goal, built properly, and documented as they actually went together. Components we supply are linked to their product pages; everything else is listed by name so you can see the whole build, not a filtered version of it.
The front stage is everything.
Our SQ builds prioritize accurate imaging, smooth tonal response and low noise floors. Typical recipes include three-way active front stages, high-fidelity amplification, DSP-controlled time alignment and sound-deadened doors. The result is a system that disappears sonically and leaves only the music.
Common components: ESB 3-way component sets, Zapco DSP amplifiers, custom sub enclosures tuned for flat in-car response.
Meter loud. Ear clean.
SQL builds walk the line between SPL performance and musical accuracy. We spec high-excursion woofers in ported or horn-loading enclosures, big alternator-grade electrical systems and amplifiers that stay stable into low impedances. Then we tune so the same car can burp numbers and play a full track without falling apart.
Common components: high-displacement subwoofers, multiple mono blocks, stiffened enclosures and upgraded charging.
Better sound, same car.
Not every build needs a trunk full of batteries. Our daily-driver recipes focus on easy-wins: a clean head unit with proper signal output, factory-location speaker upgrades, modest amplification and a single subwoofer sealed or ported to the vehicle. The outcome is a system that improves every commute without sacrificing cargo space or reliability.
