3 The following formula is a guide to deter mine current draw so you can choose the proper gauge power cable and fuses for your system. A 50% amplifier efficiency rating is used as an average.
4 Bef ore beginning, disconnect the negative (-) terminal of the batter y pr ior to working on the positive (+) terminal to pre v ent a shor t to ground. This is impor tant, unless you w ant to spend the rest of your lif e with a nic kname lik e "Spar ky ," or "Smok ey .

12 1. Adjust all amplifier input gain controls to just above minimum sensitivity (fully counterclockwise). 2. Using the cleanest source (CD), with music playing turn up the head unit until you can hear the music begin to distort. Now tur n it down a bit until you cannot hear the distortion.
13 For extra BOOM from your system, we’ve developed the QBASS™ bass contr ol cir cuit. The QBASS™ control is located to the left of the cr ossover switches and allows you to add up to 12dB of boost center ed at 40Hz by r otating the contr ol clockwise.
