INSTALLATION GUIDELINES

High-powered car audiosystems may produce sound

pressure levels that exceed thethreshold at which hearing loss mayresult.

They may also impair a driver’s ability tohear traffic sounds or emergency vehi-cles. Use common sense and practicesafe listening habits when listening to oradjusting your audio system.

1. Please read this owner’s manualcarefully before installing this ampli-fier.

2. Disconnect the battery groundterminal prior to making any elec-

trical connections.3. Check for any hazards or obstruc-

tions such as gas tanks, fuel orbrake lines, and wiring harnessesbefore mounting the amplifier.

4. Pick a mounting location that willprovide adequate access and venti-lation and protect the amplifierfrom heat, moisture, and dirt.

5. Avoid sharp metal areas when

routing cables to the amplifier, andrun RCA cables away from thepower cables and other potentiallynoisy car harnesses.




6. The amplifier should be groundedwith a short, heavy gauge wireconnected directly to the car at abare metal surface, preferably

scraped body sheet metal. Do not use factory ground locations, seat bolts, or brackets that arespotwelded.

7. Always fuse your power connectionwithin 8 to 10 inches of the batteryterminal. Use a fuse or circuit breaker rated slightly more than theon-board fuse(s) of theamplifier(s). The gauge of powerwire used should take into account the total current draw of thesystem, and the length of wireused. IASCA and other auto soundcompetition organizations havecharts available for this; you can

also find a chart in the MECP studyguide. Minimum wire gauge recom-mendations for the individual ampli-fiers are listed on the specificationpage. Always use the same gaugewire for the amplifier ground that you use for the power wire. Be sureto examine the battery ground

cable of the vehicle, and if neces-sary, upgrade it by adding an addi-tional ground wire that is the samegauge as the amplifier power wire.Remember, the amplifier can onlydeliver its rated output when it is

not current limited by the powerand ground supply wires.

8. This amplifier is designed to drive a

speaker load that measures from 2to 4 ohms. Keep in mind that heat is the long-term enemy of automo-tive electronics and the lower yourspeaker load, the more heat isgenerated. For low impedancespeaker applications or restrictedventilation installations, an externalcooling fan may be advisable.

9. Battery and ground connections tothe vehicle should be made withcrimped ring terminals of the appro-priate size (surface area is what counts); soldering the terminalsafter crimping is also recom-mended.

10. Due to the high-frequency MOSFETswitching power supply, filtering thepower cable is not generallyrequired (remember that the ampcan’t deliver full output if the powersupply is restricted). Propergrounding of the signal source ismandatory for the amplifier to

reach its performance peak. If theRCA inputs are not groundedadequately via the signal source,electrical noise from the vehiclemay be picked up in the system.

condition has cleared after approxi-mately 10-seconds the amplifierwill automatically recover.

10. Speaker Connections - Note that thetwo speakers & four speakers havebeen connected to the four terminalfollowing the (+) and (-) graphic.Your speaker terminal may bemarked (+) and (-) or there maybe red dot by one terminal whichmeans the same as (+).

Connecting the speakers in thismanner assures that the twospeaker cones will move in and out together according to the originalrecording. If one of the twospeakers is reversed, stereoimaging and bass response will bedegraded.

Refer to the specifications for thewire size to be used with youramplifier.

11. ATC Fuses - protects the amplifierfrom over current situations. Seespecification for fuse size for youramplifier. Note: The XA-3002 hasonly one fuse.

12. (+) 12 Volt Power - Connect thisterminal through a FUSE or CIRCUITBREAKER to the positive terminal ofthe vehicle battery or the positiveterminal of an isolated audio

system battery. Refer to the specifi-cations for the wire size to be usedwith your amplifier.

WARNING: Always protect this power wire by installing a fuseor circuit breaker of the appropriate size within12 inches of the battery terminal connection.

Remote Turn On - This terminalturns on the amplifier when (+) 12

volt is applied to it. Connect it tothe remote turn on lead of the headunit or signal source. If a (+) 12volt remote turn lead is not avail-able, a Remote Power Adapter(P/N #55000) can be used tosupply a remote turn on signal. DONOT connect this terminal toconstant (+) 12 volt.

Ground - Connect this terminaldirectly to the sheet metal chassisof the vehicle using the shortest wire necessary to make thisconnection. Always use wire of thesame gauge or larger than the (+)12 volt power wire. The chassisconnection point should be scrapedfree of paint and dirt. Use only

quality crimped and/or solderedconnectors at both ends of thiswire. DO NOT connect this terminaldirectly to the vehicle batteryground terminal or any otherfactory ground points.

The XA-5001, and XA-8001 amplifiers offer two positive and two negative output termi-nals for ease of connecting the speakers to the amplifier. Since these are mono amplifiers,

the speaker connectors are paralleled internally. Each amplifier is stable to 2 ohms.

NOTE! The XA-5001 and XA-8001 are not designed to work in a bridged or strappedconfiguration. Attempting to apply these configurations will damage the amplifier and

will not be covered under warranty.




CROSSOVER SETTINGS AND GAIN ADJUSTMENT

Your Xtreme Series power amplifier by Directed Audio needs to be adjusted carefully toachieve 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 theswitch 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 theimage 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 settinglow enough to keep your sound stage in front of you, without overdriving thespeaker. 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 ofmusical 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 youhear distortion before you reach the 3/4 volume setting of your head unit, reducethe 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 isheard, then back off the gain until the distortion is not audible. This setting willallow you to reach full output with all but the quietest of source material, whileavoiding excessive noise in the system.

The same procedure should be used for adjusting the amplifier when the on-boardcrossover is set to LPF or HPF, but you will also have to take into consideration theeffect that gain adjustment has on system frequency response and imaging.Again, plan on spending some time with music that you know, getting the gainand crossover settings the way you like. Test discs and analyzers may help with thisprocess, but in the end it's your ears that count - listen to the music!
