If you’re looking for something that can really power your subwoofer, then I would recommend 4000-Watt amps. The 4000 Watt amps on this list are extremely powerful. They strike a good balance between sound quality and overall durability at a reasonable price. Furthermore, they function quite efficiently and produce a rather clear and detailed sound profile.
We also did a lineup of 1000W, 2000W and 3000W amps.
