CT Sounds 300.4D // 1800 Watts RMS 4-Channel Car Amplifier

CT Sounds designed the CT-300.4D full-range 4-channel amplifier to pair perfectly with single 4-ohm midrange speakers rated at 250W RMS, like our MESO65-4 or NEO65-4. You can run (2) 250W RMS single 4-ohm speakers per channel at 2-ohm for a total of 8 midrange speakers, (4) 250W RMS single 4-ohm speakers per bridged channels (CH1-2 & CH3-4) at 4-ohm for a total of 8 midrange speakers, or power (1) 250W RMS single 4-ohm speaker per channel at 4-ohm for a total of 4 midrange speakers. Quick Facts: RMS Power @ 2Ω: 450 Watt x 4-Ch (14.4v) RMS Power @ 4Ω: 300 Watt x 4-Ch (14.4v) RMS Power @ 4Ω (Bridged): 920 Watt x 2-Ch (14.4v) Recommended Wiring Kit: AMPKIT-4GA-ELITE This multi-channel amplifier features selectable high pass, low pass, and full range modes on both CH1-2 and CH3-4, giving you the flexibility to tailor your system. The “HPF” blocks frequencies below its set level, the “LPF” blocks frequencies above, and “FULL” plays the entire band. For example, set the HPF around 25% (roughly 150Hz) when running midrange speakers, use full range mode for component speakers, or select low pass when running a dual 2-ohm subwoofer at 4-ohm bridged. Inside, a Texas Instruments CD4047BM clock circuit synchronizes all IRS2092 driver IC chips to the same frequency for stable, consistent output across every channel. The amplifier also includes 4-way protection: high voltage, low voltage, overcurrent, and temperature. Plus, a reverse polarity diode - if the power and ground are connected incorrectly, the diode will blow to shield the circuit, and once removed, the amplifier will function again, giving you peace of mind that your system is safe.
