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\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"color: #000000;\" data-mce-style=\"color: #000000;\"\u003eEasy to set for optimum performance\u003c\/span\u003e\u003c\/h4\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\" data-mce-src=\"https:\/\/images.crutchfieldonline.com\/ImageHandler\/scale\/400\/270\/products\/2013\/7\/575\/h575P300X2-o_ClipLight1.jpg\"\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\" data-mce-style=\"color: #000000;\"\u003eP300X2 control panel shown as example\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\" data-mce-style=\"color: #000000;\"\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'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\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"color: #000000;\" data-mce-style=\"color: #000000;\"\u003eKeeps an eye on things while playing\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\" data-mce-style=\"color: #000000;\"\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.
