Signal Connections
POWER CONNECTIONS:
prevent any damage to the audio components. Leave the ground wire disconnected until all components
are hooked up and the stereo is ready to play. Remove the power terminal from the AX202P / AX303P
before fastening the wires into the correct slots as a precaution. Make sure you are looking at the terminal
with the set screws facing upwards while following the instructions.
Before connecting anything, be sure to disconnect the ground terminal from your battery to
B+:
positive (+) 12V lead using the same source that powers your amplifiers. This should eliminate any
chance of picking up noise due to voltage differences. If you decide to run power wire for the crossover
directly to the battery, be sure to add an in-line fuse within a recommended 18 inches of the battery post.
This will protect both the system and the vehicle from possibly dangerous electric shock. Use a minimum
of 16 AWG stranded copper wire for this application and be sure to apply grommets whenever the power
wire is run through any metal wall.
The first slot from the left is the B+ or positive (+) 12V terminal. Connect this terminal to a
GROUND:
locate a solid metal area close to the crossover that is a good source of ground (preferable the floor). Your
best ground will come from a grounding point attached directly to the frame of the vehicle. Investigate the
area you wish to use for electrical wires. Do not try to move vacuum, break or fuel lines. Using either a
wire brush or sandpaper to eliminate unwanted paint to supply a better contact when grounding. Use the
same gauge wire for ground as you did for the power wire. Terminate your ground wire using the correct
size ring terminal and attach it to bare metal using a #8 sheet metal screw. It is important for this
connection to be solid. To complete the job, spread silicon over the screw and bare metal to prevent rust
and/or water from entering.
The second slot from the left is the ground or B- terminal. To ground your AX202P / AX303P,
REMOTE:
switched +12V source. Typically, remote turn-on leads are located by the source unit, which are used to
turn on and off all processors in correspondence with the source unit. If a radio does not have a remote
turn-on, then a power antenna wire may be used.
The third terminal from the left is the remote turn-on. This terminal must be connected to a

Warning / Disclaimer
WARNING
Investigate the layout of your automobile thoroughly before drilling or cutting any holes.
Take care when you work near the gas tanks, gas lines, hydraulic lines, and electrical wiring.
Attach the system securely to the automobile to prevent damage, particularly in the event
of an accident. Do not mount the system so that the wire connections are unprotected
or are subject to pinching or damage from nearby objects.
The +12V DC power wire must be fused at the battery positive terminal connection.
Before making or breaking power connections at the system power terminals,
disconnect the +12V wire at the battery end. Confirm your radio/head unit and/or other
equipment is turned off while connecting the input jacks and speaker terminals.
If you need to replace the power fuse, replace it only with a fuse identical to that
supplied with the system. Using a fuse of different type or rating may result in damage to
