The GRS 5AS-4 5-1/4" Car Replacement Speaker offers a straightforward upgrade for drivers seeking to enhance their vehicle's low-frequency performance without extensive modifications. Designed as a dedicated bass mid-bass subwoofer, this 4-ohm driver is ideal for reinforcing the lower end of factory or aftermarket audio systems, providing a fuller, more immersive listening experience. Its compact form factor makes it particularly well-suited for installation in standard 5-1/4" openings found in many cars, trucks, and SUVs, where space is at a premium but improved bass response is desired.

Technically, the 5AS-4 features a nominal diameter of 133.3mm and a mounting depth of just 57.2mm, ensuring compatibility with shallow enclosures or door panels. With a sensitivity rating of 87dB (SPL at 1m/2.83V) and a maximum power handling of 60 watts, it strikes a balance between efficiency and output capability. The 4-ohm impedance simplifies integration with most car audio amplifiers and head units. Whether used as a dedicated mid-bass driver in a multi-speaker setup or as a simple drop-in replacement, this GRS speaker delivers clear, controlled low-end reinforcement that adds depth and impact to your car's sound system.
