Tectonic-D500 4Ω 500W Mono Class-D Subwoofer Amp Module

$49.00 USD

Successor to JLA-250D. Compact amplifier module designed for subwoofer and rugged high power applications (Input and output can accept full range 20Hz to 20kHz).

The module is designed to be easily retrofitted in the power amp section of a busted plate amp or subwoofer amp.

Capable of high current output without the aggressive limiter / protections found in other class-d implementations. No feeling of restrained performance and will drive the subwoofer to its max duties.

It uses flat wire, high current, low loss ferrite core output filter inductor.

Housekeeping supplies are already integrated so only the main split power supply is required.

Can be easily mounted on any type of heatsink or plate-amps. Requires only 3 to 4 drilling holes.

Each Tectonic-D500 is tested and quality checked before shipping to guarantee a fault-free product.

Package Includes
1 pc assembled and tested mono module without heatsink.
