Massive Car Audio 2x 12" Subwoofer 2800W DVC 4 Ohm & 4000W Monoblock Amplifier

Massive Audio's GTX subs use tight red stitching that's sewn through a UV-treated non-pressed paper cone onto an EROM foam surround. Then it's bonded to a heavy gauge steel basket that's bolted to double stacked high flux Y30 70-150oz Strontium ferrite magnets with a 10mm top plate. Then everything dances on a springy poly cotton spider with high powered woven tinsel leads that connect to spring-loaded 5-way binding nickel-plated speaker connectors. These woofers scream sound quality and truly represent Massive Audio's commitment to value and performance.

NANO EDGE Series Amplifiers use a famous Nano Block Military speck circuit board and "N" drive MOSFET power supplies to insure performance but they now have several new cutting-edge features like RCA inputs that can take RCA or Speaker levels at up to 10 Volts in! This built-in money-saving OEM line converter is found in every "EDGE" model, and every E3 model uses a DC off-set music sensing system to activate the ATO (Auto Turn On).
