[. . . ] Arrange wiring and cables in compliance with the manual to prevent obstructions when driving. When drilling holes in the chassis for installation, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring. Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc. [. . . ] ⷠIf you add an optional noise suppressor, connect it as far away from the unit as possible.

Be sure to observe correct channel connections; Left to Left and Right to Right. Be sure to observe correct speaker output connections and phasing in relation to the other speakers in the system. 3 Battery Lead (Yellow) (Sold Separately) Be sure to add a 80 amp fuse as close as possible to the battery's positive (+) terminal. This fuse will protect your vehicle's electrical system in case of a short circuit. If you need to extend this lead, only use 21mm2 - 13mm2 (the wire gauge) for this connection. 4 Remote Turn-On Lead (Blue/White) (Sold Separately) Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of your head unit. 5 Ground Lead (Black) (Sold Separately) Connect this lead securely to a clean, bare metal spot on the vehicle's chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (­) terminal of the vehicle's battery. Ground all your audio components to the same point on the chassis to prevent ground loops. 6 Power Supply Terminal 7 Speaker Input Leads These leads are input leads for use with head units not equipped with preamp outputs.
