[. . . ] This is recommended because the current delivery of the factory electrical system was designed only to accommodate electronics supplied by the auto manufacturer. The Orion 2500D has two separate four-gauge power and ground inputs. Both pairs of connections must use 4 AWG power wire for proper operation. Failure to do this may damage the amplifier and is not covered under warranty. The 2500D cannot be operated in a bridge or strapped configuration, attempting to do so will damage the amplifier. ©2004 Directed Electronics, Inc. NOTE: WARNING! 12 Speaker Connections The Orion 300D, 600D, 1200D, and 2500D amplifiers offer two positive and two negative output terminals for ease of connecting the speakers to the amplifier. Since these are mono amplifiers, the speaker connectors are paralleled internally. Each amplifier is stable to 1W. Bridging For bridging into a single speaker load, the Orion 600D and 1200D have the ability to be bridged with another amplifier of the same model. To do this you must utilize the COPY/GAIN/MASTER switch settings. For the MASTER amplifier, set the switch setting to MASTER. This will route the signal through RCA to the other (slave) amplifier. Refer to Auxiliary Output Configuration section of this guide. To set the PHASE switch on the (slave) amp, move the phase switch from 0 to 180, exactly opposite of the master amp. Refer to the Phase Switches section of this guide. On the (slave) amplifier be sure to turn off all crossovers. For the speaker connections, connect the positive (+) speaker lead from the speaker to the positive (+) speaker terminal of the master amplifier. On the negative (-) speaker connection, take the negative (-) speaker terminal of the master amplifier and connect it directly to the negative (-) speaker terminal of the (slave) amplifier. The remaining positive (+) speaker terminal of the (slave) amplifier must be connected to the negative (-) speaker lead from the speaker. The impedance of the speaker must not exceed 2W. NOTE: NOTE: There is no Copy/Gain/Master switch on the 300D. For best results, connect both negative speaker terminals on the master amp to both negative terminals on the slave amp using at least 12 AWG cable. The Orion 2500D is not designed to work in a bridged or strapped configuration. Attempting to apply these configurations will damage the amplifier and will not be covered under warranty. WARNING! ©2004 Directed Electronics, Inc. 13 AMPLIFIER INSTALLATION Choosing Mounting Locations The location of your amplifier will depend on several important issues. [. . . ] Refer to the Internal Crossover Configuration section of this guide for detailed instructions. Check system with known work ing speakers and fix or replace as needed. Speakers are blown Poor bass response Speakers wired with wrong Check speaker polarity and fix polarity causing cancellation as needed. at low frequencies Crossover set incorrectly Reset crossovers. Refer to the Internal Crossover Configuration section of this guide for detailed instructions. Impedance load at amplifier Check speaker impedance load, is too low if below 1W, rewire speakers to achieve higher impedance. [. . . ]
