[. . . ] All Pyle products are carefully constructed and thoroughly tested before shipment. Products purchased in the USA are warranted to be free of defects in material and workmanship for two (2) years from the date of purchase. This warranty is limited to the original retail purchase. Should the product fail due to factory defects in material or workmanship, your unit will be repaired or replaced at the sole discretion of Pyle. [. . . ] bass boost level control this control permits adjustment of the bass level up to an increase of approximately 18 dB. low level inputs this amp features gold-plated RCA input jacks for high impedance input. Use these with car stereo output which uses RCA-type connector cables. high level inputs if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. power LED this indicator is illuminated when power is applied. protection LED this indicator is illuminated when built-in protection circuitry is activated. power fuse the fuse protects the amplifier and your car's electrical system from short circuit conditions. power terminals use these connectors to deliver power, ground and remote turn-on control to the amplifier. speaker connections these terminals are 14K gold plated to guarantee high conductivity and minimum signal loss. 35 Watts x 4 50 Watts x 4 250 Watts x 4 15 Hz-30 KHz 10K Ohms 100 Ohms 250mV 2. 5V 14. 4V DC Neg.

" If you wish to use the internal crossover to power a driver of specific frequency range, use the "LOWPASS" or "HIGHPASS" settings. input level control use this control to match the outputs of your head unit to the amplifier. Starting with your head unit set at about the 2 o'clock position, increase the amp level control until distortion begins to occur, and reduce slightly from this point. low pass frequency control when the crossover selector switch is in "low pass" mode, this control sets the upper frequency limit for audio program sent to the speakers. high pass frequency control when the crossover selector switch is in "high pass" mode, this control sets the lower frequency limit for audio program sent to the speakers. Remote Bass Boost Plug in the Remote Bass Boost Control wire in here. bass boost level control this control permits adjustment of the bass level up to an increase of approximately 18 dB. low level inputs this amp features gold-plated RCA input jacks for high impedance input. Use these with car stereo output which uses RCA-type connector cables. high level inputs if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. power LED this indicator is illuminated when power is applied. protection LED this indicator is illuminated when built-in protection circuitry is activated. power fuse the fuse protects the amplifier and your car's electrical system from short circuit conditions. [. . . ] If this occurs, carefully inspect the system to determine the source of the problem. · If the shutdown was a result of a thermal overload condition, allow the amplifier to cool down before attempting to restart it. · If the shutdown was a result of an input overload, or speaker short circuit, be sure to correct the condition before restarting. The amplifier can be restarted by turning the remote power OFF and then ON again. Check both in-line and built-in fuses. [. . . ]
