WARNING  
High-powered car audio  
systems may produce sound  
pressure levels that exceed the  
threshold at which hearing loss may  
result.  
They may also impair a driver’s ability to  
hear traffic sounds or emergency vehi-  
cles. Use common sense and practice  
safe listening habits when listening to or  
adjusting your audio system.  
INSTALLATION GUIDELINES  
1. Please read this owner’s manual  
carefully before installing this ampli-  
fier.  
4. Pick a mounting location that will  
provide adequate access and venti-  
lation and protect the amplifier  
from heat, moisture, and dirt.  
2. Disconnect the battery ground  
terminal prior to making any elec-  
trical connections.  
5. Avoid sharp metal areas when  
routing cables to the amplifier, and  
run RCA cables away from the  
power cables and other potentially  
noisy car harnesses.  
3. Check for any hazards or obstruc-  
tions such as gas tanks, fuel or  
brake lines, and wiring harnesses  
before mounting the amplifier.

6. The amplifier should be grounded  
with a short, heavy gauge wire  
connected directly to the car at a  
bare metal surface, preferably  
scraped body sheet metal. Do not  
use factory ground locations, seat  
bolts, or brackets that are  
spotwelded.  
not current limited by the power  
and ground supply wires.  
8. This amplifier is designed to drive a  
speaker load that measures from 2  
to 8 ohms. Keep in mind that heat  
is the long-term enemy of automo-  
tive electronics and the lower your  
speaker load, the more heat is  
generated. For low impedance  
speaker applications or restricted  
ventilation installations, an external  
cooling fan may be advisable.  
7. Always fuse your power connection  
within 8 to 10 inches of the battery  
terminal. Use a fuse or circuit  
breaker rated slightly more than the  
on-board fuse(s) of the  
amplifier(s). The gauge of power  
wire used should take into account  
the total current draw of the  
system, and the length of wire  
used. IASCA and other auto sound  
competition organizations have  
charts available for this; you can  
also find a chart in the MECP study  
guide. Minimum wire gauge recom-  
mendations for the individual ampli-  
fiers are listed on the specification  
page. Always use the same gauge  
wire for the amplifier ground that  
you use for the power wire. Be sure  
to examine the battery ground  
cable of the vehicle, and if neces-  
sary, upgrade it by adding an addi-  
tional ground wire that is the same  
gauge as the amplifier power wire.  
Remember, the amplifier can only  
deliver its rated output when it is  
9. Battery and ground connections to  
the vehicle should be made with  
crimped ring terminals of the appro-  
priate size (surface area is what  
counts); soldering the terminals  
after crimping is also recom-  
mended.  
10. Due to the high-frequency MOSFET  
switching power supply, filtering the  
power cable is not generally  
required (remember that the amp  
can’t deliver full output if the power  
supply is restricted). Proper  
grounding of the signal source is  
mandatory for the amplifier to  
reach its performance peak. If the  
RCA inputs are not grounded  
adequately via the signal source,  
electrical noise from the vehicle  
may be picked up in the system.

HPF attenuates low frequencies and

frequencies and is used for  
subwoofers speakers.  
The 1500X amplifier will cycle off and automati-  
cally turn back on when the fault condition clears.  
The amplifier should be inspected for proper venti-  
lation clearance on all sides of the amplifier (2-  
inches). The speaker wiring should be inspected  
for any shorts.  
NOTE:  
The 1500X and 2300X amplifiers have one  
combined Power/Protection (BLUE/RED) LED,  
the 4600X amplifier has separate Power (BLUE)  
and Protection (RED) LEDs.

CROSSOVER SETTINGS AND GAIN ADJUSTMENT  
Your Xtreme Series power amplifier by Directed Audio needs to be adjusted carefully to  
achieve maximum performance. These are some guidelines to follow when fine-tuning  
the amplifier.  
For full-range and simultaneous stereo/mono bass applications, the crossover selec-  
tion switch should be set to FLAT. If the amplifier is driving your subwoofers, set the  
switch to LPF, and for mid-bass/midrange output, set to HPF.  
The crossover frequency control needs to be adjusted to suit your particular system.  
For subwoofer applications, try to keep the setting low enough to prevent the  
image smearing (you should not be able to hear male voices from the subwoofer)  
but not so low as to create a gap between the subwoofer and the mid-  
bass/midrange speakers. For mid-bass/midrange settings, try to keep the setting  
low enough to keep your sound stage in front of you, without overdriving the  
speaker. It will be to your advantage to spend some extra time with this adjust-  
ment, listening to familiar music or system set-up discs to achieve the kind of  
musical reproduction that you prefer.  
The gain adjustment allows you to set proper signal match for clean, quiet ampli-  
fier operation. For full-range and simultaneous stereo/mono bass applications,  
start by playing some music you are familiar with. With the gain adjustment on  
the amplifier in the middle of its rotation, bring up the volume on your head unit  
to the 3/4 volume setting or until you start to hear distortion or clipping. If you  
hear distortion before you reach the 3/4 volume setting of your head unit, reduce  
the gain setting on the amplifier and start to raise the head unit volume again.  
When you can listen to the music at or slightly above 3/4 on your head unit  
without audible distortion, slowly raise the gain of the amplifier until distortion is  
heard, then back off the gain until the distortion is not audible. This setting will  
allow you to reach full output with all but the quietest of source material, while  
avoiding excessive noise in the system.  
The same procedure should be used for adjusting the amplifier when the on-board  
crossover is set to LPF or HPF, but you will also have to take into consideration the  
effect that gain adjustment has on system frequency response and imaging.  
Again, plan on spending some time with music that you know, getting the gain  
and crossover settings the way you like. Test discs and analyzers may help with this  
process, but in the end it's your ears that count - listen to the music!
