RL1200.4 - L-3 Compact Class Amplifiers

The RL1200.4 is a compact 4-channel amplifier built for full-range system upgrades where space is limited but output isn't. Rated at 300W x 4 at 2 ohms and bridgeable to 520W x 2, it delivers real power in a 6.67" x 4.92" footprint. Onboard HPF and LPF crossovers (30–300 Hz) make it a flexible fit for both speaker and component applications.

• 300W x 4 @ 2 ohms (14.4V) with bridged output up to 520W x 2 @ 4 ohms
• Full-range crossover control — independent HPF and LPF, each adjustable from 30 Hz to 300 Hz
• 4-way protection circuit — thermal, voltage, and speaker DC protection for reliable long-term operation
• Low-level input sensitivity from 220mV to 12V accommodates most head unit output levels
• Clip indicator at 1% THD helps dial in gain without distortion
• Compact form factor at 6.67" x 4.92" x 2.01" for flexible mounting in tight installs
• 90A fuse rating with 9V–16V operating voltage range
