unpacking
Adjust the gain of the subwoofer amplifier to blend in with the midrange and high frequency speakers.
Ideally the amplifier powering the ie subwoofer has an electronic crossover, If it does adjust it for the
best sound quality, the crossover setting should be between 50-100 Hz. If the amplifier does not have
an electronic crossover, a 5 mH coil in series with the enclosure is acceptable. If the system is lacking
mid-bass response reverse the speaker wires to the ie subwoofer and listen again. If the mid-bass
response improves leave it alone, if not return the wires to the original position.
These subwoofers are heavy. Rather than lifting the unit out of the shipping carton, turn the open
carton over, and lift it off the subwoofer. Then remove the packing corners from the subwoofer and
then remove it from the plastic bag.
placement
1. First turn factory radio to 3/4 volume.
Unlike high frequency sound, our ears have difficulty locating the source of deep bass sounds.
Consequently, you have a fair amount of flexibility in where you place the subwoofer in your vehicle.
Typically the subwoofer is mounted in rear of the vehicle, either in the trunk, hatchback, or rear cargo
area. For proper performance the port must not be closer than 3" from any walls, this will cause the
performance to suffer. The enclosure can stand up or lie it on its side.
2. Turn up/down gain to blend with mid and high speakers.
3. Adjust crossover of amplifier for best sound.
mounting locations
Brackets are supplied for mounting the enclosure either vertically or horizontally. Remove the proper
screws from the enclosure and replace the screws through the bracket and then into the enclosure.
Repeat for the other side. Screw the enclosure into the floor of the vehicle being careful to note where
brake and fuel lines run on the other side. Do not mount the enclosure directly against a hard surface
with out first putting down a piece of felt or cloth to prevent buzzes and rattles. Check to make sure
that the enclosure screws are tightened properly, failure to do so may cause unwanted air leaks. Check
to make sure that the screws mounting the enclosure to the floor are secure and tight.
4. Repeat steps 2 and 3 until desired sound is achieved.
warnings and tips
Always disconnect the battery ground wire before doing any work on your vehicle. Reconnect the cable
only after the installation is complete and the wiring has been checked to make sure that there are no
problems. If your radio features a code type security system, be sure you know the code before
disconnecting the battery!

system configurations
speaker connections
The ie series subwoofers are designed to integrate with a wide variety of full range speakers. A typical
installation consists of a factory stereo system driving an external amplifier powering the ie series
subwoofer. A more advanced system utilizes separate midrange and hi frequency speakers and multi-
channel amplification, such as an a/d/s/ PH30 amplifier powering 346is speakers front and rear along
with an ie series subwoofer.
The ie series subwoofers have a terminal cup mounted on one end of the speaker enclosure. One
terminal is labeled + (red) and the other one is – (black). Connect the positive (+) wire of the amplifier
to the positive (+) wire of the speaker enclosure. Then connect the negative (-) wire of the amplifier to
the negative (-) wire of the speaker enclosure.
factory upgrade
maintenance
Normal maintenance of the subwoofer consists of keeping the unit clean and dust-free. Use a soft
cloth or brush to remove dust without scratching or marring the finish. Do not use strong cleaners or
solvents of any kind. Avoid spray cleaners or waxes, they can produce spotty glossy areas.

troubleshooting
No sound
Check the speaker cables connected to the inputs of the
subwoofer.
Buzzes and rattles
Locate the source of the noise and secure it. Place carpet,
or felt under the subwoofer then securely mount it down.
