The phone jack type connector labeled “LPL” is for connection of an optional remote Low Pass Level control. Phoenix Gold’s LPL44 provides remote control of the bass level from the front dash and is connected to the amp by a 20 foot cable (included). The LPL does not increase bass output, but allows 20dB of attenuation. The LPL44 will not affect frequency as this is controlled by the crossover frequency setting on the amplifier.
