High-Level Input
(speaker cables)
Low-Level Input
(RCA)
Speaker Connections
Connect speaker wires observing polarity.
The minimum impedance load for the
DA301L and DA704L is 2 ohms. Use of loads
lower than these is not recommended and
may cause amplifier damage.
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 t wisted 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.

Note: Do not use both low and high level inputs
at the same time - connect only one or the other.
