Bundle Contents

This bundle pairs a 12-inch thin down-firing subwoofer enclosure with a 400-watt mono Class D amplifier. The subwoofer uses a 2-ohm passive radiator design housed in a factory-optimized box. The amplifier delivers up to 400 watts into a single bass channel with variable bass boost and 12dB crossovers. Together they provide a matched low-frequency upgrade for car audio systems.

Ideal Install Scenarios

The shallow enclosure depth suits vehicles where cargo space is limited and a traditional ported box will not fit. The amplifier accepts high-level input signals up to 40 volts for direct connection to factory speaker wires. Buyers needing more than one subwoofer or a different impedance load should consider other options. The fixed 2-ohm enclosure wiring limits amplifier pairing flexibility.

Deciding Specification

The subwoofer enclosure measures 27-1/2 by 14-5/8 by 6-1/8 inches and requires that exact mounting footprint. Verify the available space in your vehicle before purchase. The amplifier measures 8-1/8 by 6-3/4 by 2-3/8 inches and needs a matching installation location. Physical fit is the single specification that determines whether this bundle works in your application.

Questions about this item

How is the 46CXA4001 amp installed and what wiring step is commonly missed?

Mount the amp using its 8-1/8 x 6-3/4 x 2-3/8 inch chassis, run power and ground cables to the battery, connect the remote turn-on lead, then use the high-level inputs for factory stereos — many forget to set the input-mode switch to high-level and leave it on RCA.

What maintenance will the 48TRTP122 subwoofer enclosure need over time?

Check the passive radiator surround for cracking once a year, verify the down-firing port stays clear of cargo, and re-torque the enclosure mounting bolts after the first few weeks of vibration.

What limit appears first during extended heavy bass with this 400-watt amp and 2-ohm sub?

The amp thermal protection engages first when the Class-D heatsink cannot shed heat fast enough during sustained 400-watt output, muting the bass until it cools.
