The cover screws are removed with the included 2.5 mm Allen wrench. The rotary controls and recessed slide switches require the use of a narrow flat blade screwdriver (not included) to make adjustments. The front and rear sections of the amplifier have independent gain and crossover controls.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Level:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2-position switch; High (speaker level) or Low (line level)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eseparate front and rear rotary controls; range is dependent on the input level switch setting; high 800mV to 20V and low 200mV to 5V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Crossover:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMode:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2-position switch; Full Range or High Pass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3-position switch; 65 Hz, 85 Hz, or 115 Hz; 12dB\/octave slope\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Crossover:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMode:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3-position switch; Full Range, High Pass, or Low Pass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3-position switch; 65 Hz, 85 Hz, or 115 Hz; 12dB\/octave slope\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eConnections:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe power and speaker wires extend 11\" from the amp and not terminated.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethe power wire has an in-line waterproof fuse holder with a 15-amp ATM fuse installed; it appears to be approximately 12-gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethe ground wire appears to be approximately 12-gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote Turn-on:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethe remote wire appears to be approximately 16-gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker Outputs:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethe four pair of speaker outputs appear to be approximately 16-gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA Inputs:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003etwo pair of stereo RCA inputs, each on the end of 6\" pigtails; compatible with preamp level and speaker level signals (\u003cspan style=\"color: #000000;\"\u003espeaker wire to RCA adapter required when using speaker level inputs)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eat 14.4 volts and 1% THD\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4Ω:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e50 watts RMS x 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2Ω:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e65 watts RMS x 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e130 watts RMS x 2 into 4Ω\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Specs:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHertz also published the power output at 14.4 volts and 10% THD; 60 watts RMS x 4 into 4Ω and 75 watts RMS x 4 into 2Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal to Noise Ratio:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e95 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.2% (at 100 Hz into 4Ω)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":40202359603261,"sku":"HMP4D","price":379.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1344\/1149\/products\/HMP4D1.jpg?v=1661955680","url":"https:\/\/froomanscarstorio.shop\/products\/hertz-hmp4d","provider":"Freemans Car Stereo","version":"1.0","type":"link"}
