GPL Series Connections Connecting the GPL Series to your system is easy. The rear panel includes two (2) parallel NL4 and a barrier strip connector. Run your speaker wires from your ampli er to the speaker; you can use either input connector. Use the correct gauge of stranded insulated speaker cable according to the power handling ability of your GPL Series cabinet.
