Hifonics BXX4000.1D (BXX40001D)

4000W Max Brutus Series Super Class D 1-Ohm Stable Monoblock Amplifier w/ Bass Knob Included
Quantity: 2

Hifonics BXX4000.1D

BXX4000.1D

Sometimes, you just need to give your subs a little boost. Sometimes, they need a decent amount of power. Sometimes, you gotta blow the trunk lid off. That's where the Hifonics BXX4000.1D comes in. If you're trying to supply a maximum amount of power to your presumably powerful subwoofers, here ya go.

BXX4000.1D

Hifonics put a lot of cool features in the BXX4000.1D aside from raw power. The Ultra-Fi MOSFET power supply does more than push power to your subs, it makes sure what it's pushing sounds good. Why settle for just pure wattage? Make sure it sounds like it should!

Pair that with the Super D-Class design circuitry, the classically awesome-looking heatsink and a built-in electronic equalizer, and you've got a lot great sound to go with that high wattage. Not enough power? Strap it! If your system demands even more, the BXX40001.D is ready to team up with another amp to supply all the power you need. Just make sure your electrical system is up to the task.
