CAB (Car Audio Bargain), now operating as Apex Audio, is an American amplifier manufacturer that produces high-power Class D amplifiers in the same facility as Sundown Audio. Known for exceptional value and overperformance, their flagship CAB-22 is rated at 2,200 watts but consistently dynos at 2,450+ watts—certified by Sundown's own testing. Using half-bridge technology identical to premium Sundown amplifiers, CAB delivers competition-level power at budget-friendly prices. From the CAB-22 to the massive CAB-45 (4,500W), these heavy-duty amplifiers have earned a reputation as the best bang-for-the-buck in car audio among bassheads seeking maximum power per dollar.
