INSTALLATION GUIDELINES

1.Please read this owner’s manual carefully before installing this ampli- fier.

2.Disconnect the battery ground terminal prior to making any elec- trical connections.

3.Check for any hazards or obstruc- tions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier.

4.Pick a mounting location that will provide adequate access and venti- lation and protect the amplifier from heat, moisture, and dirt.

5.Avoid sharp metal areas when routing cables to the amplifier, and run RCA cables away from the power cables and other potentially noisy car harnesses.

6.The amplifier should be grounded with a short, heavy gauge wire connected directly to the car at a bare metal surface, preferably scraped body sheet metal. Do not use factory ground locations, seat bolts, or brackets that are spot welded.

7.Always fuse your power connection within 8 to 10 inches of the battery

terminal. Use a fuse or circuit breaker rated slightly more than the

on-board fuse(s) of the amplifier(s). The gauge of power wire used should take into account the total current draw of the system, and the length of wire used. IASCA and other auto sound competition organizations have charts available for this; you can also find a chart in the MECP study guide. Minimum wire gauge recom- mendations for the individual ampli- fiers are listed on the specification page. Always use the same gauge wire for the amplifier ground that you use for the power wire. Be sure to examine the battery ground cable of the vehicle, and if neces- sary, upgrade it by adding an addi- tional ground wire that is the same gauge as the amplifier’s power wire. Remember, the amplifier can only deliver its rated output when it is not current limited by the power and ground supply wires.

8.This amplifier is designed to drive a speaker load that measures from 2 to 8 ohms. Keep in mind that heat is the long-term enemy of automo- tive electronics and the lower your
