Two Fierce 12s Dual 4 Ohm Subwoofers Matched up to the R6 8000 Watt Max Mono Block Amplifier! 

The FIERCE12s has Dual 3" Voice Coils, Ribbed Foam Surrounds with Heavy Duty Cast Aluminum Baskets. Carefully selecting each component from the Tinsel Leads, Direct Connected 8 Gauge Pure Copper Wire to the Double Stacked Strontium Ferrite Magnets we have created a Subwoofer that goes Deeper & plays Louder than our competition.

The R6 features variable low pass crossovers for system flexibility. To eliminate any possible weak link we’ve spared no expense in offering the best possible connections with Tiffany style RCA jacks for as well as an oversize nickle plated terminal block for power input & speaker output. 

Stable at 0.5 Ohm with a high quality Class D PCB layout that includes built in auto sensing turn on function for vehicles that do not have the ability for RCA output, selective Bass Boost EQ for fine tuning, soft delay remote turn on/off circuit that eliminates pops and clicks.

The R6 Amplifier utilizes a MOSFET power supply for high output and increased stability, variable gain control and remote level control port for optional controller. With dynamic features like its Parametric EQ with Q-Control and Built-In Auto Sensing Turn-On the Rage R6 Amplifier blends power and performance with sleek design allowing you to Rage in style. 

What does all this translate to? Simply, amplifiers you can count on for rigorous competition and yet flexible and affordable enough to use as any system anchor.
