INSTALLATION

Amplifier Connections

2 Speakers (stereo)

Subwoofer (mono)

Speaker Connections Connect speaker wires observing polarity. The minimum impedance load for the DA304, DA602, DA604 and DA904 is 2 ohms stereo and 4 ohms bridged. Use of loads lower than these is not recommended and may cause amplifier damage. The DA304, DA602, DA604 and DA904 can be wired for stereo, bridged or

2-8 ohms

1-8 ohms

stereo/bridged simultaneous operation.

Input Signal Connections

Low Level Input (RCA)

Low level (RCA) input signal is preferred for best performance. Typical trunk- mount amplifier installations require a 17-20 foot RCA cable. Most trucks and under-seat applications require a 6-9 foot RCA cable. Using twisted pair construction RCA cables will minimize noise.

High-Level Input (speaker cables)

High Level Input

(Speaker Wire)

High level inputs should only be used when RCA outputs are not available from the head unit. Connect the head unit speaker outputs to the high level input connector as shown below. The black wire (signal reference ground) may or may not require a connection to chassis ground

-depending on your particular installation.

Low-Level Input (RCA)

Note: Do not use both low and high level inputs at the same time - connect only one or the other. High level inputs not available on DA4001, DA6001 and DA8001.
