Rockford Fosgate 4-Channel Amplifiers (36)

Rockford Fosgate Power T1000x5ad Compact 5-channel car amplifier 100 watts RMS x 4 at 2 to 4 ohms + 600 watts RMS x 1 at 1 to 2 ohms Super-compact, bursting with powerRockford Fosgate's Power Series T1000X5ad 5-channel amplifier can send 100 watts RMS each to four separate speakers while delivering up to 600 watts RMS to a subwoofer. Or you could use this tiny powerpack to run a couple of high-performance components with 200 watts each along with 600 watts RMS for the sub. A dual-fan forced air cooling system keeps this sturdy little amp from overheating, so it can play hard for a long time. Class AD: accurate and powerfulRockford Fosgate uses their proprietary Class AD amplifier technology, combining the high fidelity of a Class A system with the high efficiency of their special Class D technology, to bring you this ultra-efficient, high-output amplifier. In other words, this compact amp produces more power with less current draw from your vehicle's charging system than most other amps on the road today.Rockford Fosgate's high-tech solutions yield more powerThis Power Series amplifier actively monitors speaker and subwoofer performance, using Rockford Fosgate's Constant Power technology. A speaker's impedance naturally fluctuates as it performs, fighting against your amp's output. So, just like your cruise control increases the engine's RPM to maintain your car's speed uphill, Constant Power maintains this amp's output by increasing its internal voltage and current flow when the speaker's impedance rises. This results in up to a 25% increase in the amp's total power output. Easy to set for optimum performanceRockford Fosgate's C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) setup system ensures your music will sound as clean and powerful as possible. It works like this: first download the setup tones from Rockford Fosgate, then play the tone, adjust the receiver volume until a red clip light on the amp goes out, then turn the amp gain up until a blue light comes on. It's that simple — your amplifier will be perfectly set to match your receiver's output. When your receiver reaches maximum clean volume, you'll get maximum clean power from your Power amp. At quiet listening levels, you'll hear less background noise and more of your music. Clip lights monitor distortionIf that blue light turns solid red while you're playing music, the amp's telling you that your source is distorting and you should turn it down, or risk damage to your gear. The optional PLC2 remote level control also doubles as a clip indicator, so you can see from the front seat if your music's clipping and restore pristine sound.

Rockford Fosgate Power T400-4 4-channel car amplifier 60 watts x 4 Rockford Fosgate's Power Series AmplifiersRockford Fosgate has a well-deserved reputation for building high-quality mobile audio products. Their Power Series amps occupy the top of the amplifier food chain, with fine-tuned audio controls, extreme durability, and proprietary technologies that deliver stronger, more reliable performance than most other amplifiers on the market today. Dynamic Thermal ManagementPower Series amps use Rockford Fosgate's patented, award-winning "Dynamic Thermal Management," a 3-stage cooling system that uses forced air to dissipate heat evenly across the amp and out through the large heatsinks. This results in cooler internal components, higher efficiency, and lower distortion.MEHSA is a Rockford Fosgate proprietary process that increases heat transfer from the MOSFET devices to the heatsink. This allows the heat to escape more readily from the amplifier so that the transistors stay cooler. Extra-quiet inputs"Differential Input" circuitry helps eliminate any electronically induced noise or hum that could be picked up by the input cables, allowing only clean signals to enter the amplifier. You get more music with less heat and noise in a stylish package that's up to 40% smaller than previous models.
