Product Description

Small footprint, serious punch. This 8" sub bundle excels in compact boxes, delivering agile bass with surprising depth. High-temp coils and a stout motor structure handle demanding tracks, while the mono amp’s tuning tools focus energy exactly where you want it. Copper 4 AWG wiring supports strong current for fast, articulate hits—perfect for tight cabins seeking premium low-end texture without bulk.

Features
