Amplifier Connections - Dual DA1000D Installation & Owner's Manual

Speaker Connections
Connect speaker wires
observing polarity. The
minimum impedance load
for the DA1504D is 2 ohms
stereo and 2 ohms bridged.
Use of loads lower than
these is not recommended
and may cause amplifier
damage. The DA1504D can be
wired for stereo,
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 Wire)
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 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.
