You can use the amp's high-pass filter to remove low bass from your speakers so they'll play more efficiently. You can also switch this amp into 2-channel mode to drive a couple of subwoofers with up to 200 watts RMS each. The amp's low-pass filter comes in handy for getting the right sound from your sub\/enclosure combo. The Punch EQ2 includes bass and treble boosts, in case you want to add some boom and sizzle back into the mix.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEasy to set for optimum performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"containerImageCaptionCustom marginTen borderNone floatLeft\"\u003e\n\u003cimg alt=\"P300X2 control panel shown as example\" height=\"270\" src=\"https:\/\/images.crutchfieldonline.com\/ImageHandler\/scale\/400\/270\/products\/2013\/7\/575\/h575P300X2-o_ClipLight1.jpg\" width=\"400\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cem\u003e\u003cstrong\u003eP300X2 control panel shown as example\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eOnce again, Rockford Fosgate steps away from the crowd with their C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) — a setup system that 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKeeps an eye on things while playing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf 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 amp's built-in computer keeps tabs on the output current, ensuring that plunging speaker impedances (they change during play) or even a short circuit won't hurt anything.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaintaining coolness raises efficiency and lowers distortion\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRockford Fosgate's Dynamic Thermal Management system uses forced air to dissipate heat evenly across the amp and out through the high-mass heatsink, efficiently drawing heat away from vital internal parts. Their proprietary MEHSA cooling process maximizes the heat transfer from the MOSFET devices to the heatsink, allowing the heat to escape more readily, so the transistors stay cooler and work better.\u003c\/p\u003e\n\u003cdiv class=\"containerImageCaptionLarge marginZeroAuto\"\u003e\n\u003cimg alt=\"Rockford Fosgate P400X4\" src=\"https:\/\/images.crutchfieldonline.com\/ImageHandler\/scale\/646\/646\/products\/2013\/4\/575\/h575P400X4-O.jpg\" width=\"100%\"\u003e\n\u003cp\u003e                                                \u003cem\u003e\u003cstrong\u003e     P400X4 connection panel and input clip light\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-level input capable with Auto Turn-On circuit\u003c\/li\u003e\n\u003cli\u003eFeatures C.L.E.A.N.
