JBL Enclosed Subwoofer Systems Editorial Review
The JBL GT-BassPro12 is an impressively small and convenient subwoofer that can be mounted under or behind the seat of a regular cab truck or a small car. It has a closed system and can be connected via rear speaker wires or RCA's off the head unit. While it can get loud, it lacks in producing deeper thumpier bass and feels underpowered compared to some other subwoofers. It has a decent sound quality but may require better tuning. It comes with pre-drilled holes in the corners of the enclosure and may require sheet metal screws for installation. Overall, it is a budget-friendly option for those looking for a basic upgrade to their car's sound system with decent sound quality.
