A. Install a noise kit in the main power to the music source. If the music source
has a dimmer lead, install a noise kit there also. Check all grounding points for
corrosion, paint, ECT. Scrape clean, and retighten if necessary. If noise
continues to persist, refer to note C.
B. Re-route the main power ground to a different location in the vehicle. Listen
carefully to the amount of engine noise through the system each time the ground
is changed. If relocation of the power ground has little or no effect, obtain a high
current choke (coil) with a current rating of at least one and one half times the
maximum current rating of the amplifier and splice inline with amp main power
wire. IMPORTANT: SOLDER AND INSULATE ALL CONNECTIONS. If the
noise still persists mount the amp in a different location farther away from the
engine compartment. Be sure all main power wires to the amp are routed away
from existing wiring in the vehicle.
C. Touch the center pin of the music source male plug to the center hole of the
amplifier female jack so that the music is heard. Prevent the outer ground contact
from touching the female jack on amp. If this procedure causes noise to
disappear modify the input cables by carefully removing 1-2 of the outer
insulation exposing the ground braid. Cut the braid and fold back Strip 2-3 of
insulation off a scrap piece of wire and wrap around the ground braid next to the
plug closest to the amp and wrap the entire connection with electrical tape. Try
grounding this signal ground at several different locations in the vehicle while
carefully listening to the amount of engine noise at each location. Attach this
signal ground wire to the location, which causes the least amount of engine
noise. Only one input plug needs the signal ground wire attached, the other input
need only have its ground braid broken.
