(RCA)

Speaker Connections

Connect speaker wires

observing polarity.The

minimum impedance load

for the DA604D and DA954D

is 2 ohms stereo and 2

ohms bridged. Use of loads

lower than these is not

recommended and may

cause amplifier damage.The

DA604D and DA954D can be

wired for stereo,bridged or

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 6-9foot RCA cable. Using twisted pair

construction RCA cables will minimize noise.

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.
