DESC: These amps are so extreme, Boss had to give them an additional X! Exxtreme power is what you get from these high current, low impedance amps. You can even load them down to half an ohm for maximum power output! These high current Blade Exxtreme series amps are equipped with internal fans to dissipate heat, keeping these bad boys cool even under the most “exxtreme” loads. The “B-L-A-D-E” logo is illuminated in red lights on the top of the amp for the most cutting edge look. Plug in the included bass boost knob control and you’re ready to blow away your competition
