DPA250 INSTALLATION
Amplifier Connections
Speaker Connections
Connect speaker wires observing
polarity. The minimum impedance
load is 2 ohms stereo and 4 ohms
bridged. Use of loads lower than
these is not recommended and
may cause amplifier damage.
The DPA250 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. If your head unit does not
include low level (RCA) outputs, an optional high-to-low adapter may be required (sold
separately). 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.
