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 (1 ohm on D2205 Sub Output). Keep in mind that heat is the long-term enemy of automotive electronics and the lower your speaker load, the more heat is generated. For low impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable.

9.Battery and ground connections to the vehicle should be made with crimped ring terminals of the appro- priate size (surface area is what counts); soldering the terminals after crimping is also recommended.

10.Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can't deliver full output if the power supply is restricted). Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system.

FRONT PANEL CONNECTIONS/STATUS LED

1.ESP® Port - connection port for Bitwriter® or ESP2 security system.

2.ESP® Status LED - indicates ESP® functionality and is used to diag- nose ESP® features.

3.RCA Input Jacks - accepts line level outputs from head units or signal

processors at voltages between 250 mV and 7.5 volts. (A1004 and D2205 also have a Rear Input.)

4.RCA Output Jacks - these pass through RCA jacks can be used to send a signal to a second amplifier.
