Caution!

This symbol warns the user of a potential risk or hazard if instructions are not followed.

⇒ This arrow symbol points to a specific instruction for avoiding a potential hazard.

1. Installation

1.1 Installation- Mounting the Amplifier

Step 1- Disconnect the negative (-) battery cable before mounting the amplifier or making any connections. Check the battery and alternator ground (-) connections. Make sure they are properly connected and free of corrosion

Step 2- Choose a mounting location for your amplifier. Find a location on a flat surface away from heat and moisture. Be sure the mounting location and the drilling of pilot holes for mounting will not present a hazard to any wires, control cables, fuel lines, fuel tanks, hydraulic lines, or other vehicle systems or components. Common mounting locations are under the front passenger seat, or in the trunk area. Choose a location with unimpaired air circulation. The amplifier will dissipate heat more efficiently if mounted vertically.

Step 3- Use the supplied screws. Place the amplifier in the mounting location, and mark the positions of the holes with a marker, pen or pencil. Carefully drill the mounting holes in the marked positions.

Caution!

⇒ Check carefully before drilling any pilot holes.

Step 4- Use the supplied mounting screws to securely fasten the amplifier to the mounting surface.

1.2 Installation- Power Connections

Step 1- Run a power cable from the battery to the amplifier mounting location. Use rubber grommets to protect the cable anywhere it has to go through metal.

T3 4600,T3 4320,T3 2700,T3 2600,T3 2300,T3 5600,T3 1000 Use #8 AWG or larger power and ground cable.

T3 2160 - Use #10 AWG or larger power and ground cable.

Step 2- Connect one end of an in-line fuse holder to the power cable.

Connect the other end of the fuse holder to the positive battery post with 20 cm (or less) of the same cable. This fuse location will protect the system and the vehicle against the possibility of a short circuit in the power cable. Be sure to use a fuse and fuse holder adequate for the application. Do not place a fuse in the holder at this time.

The maximum fuse rating for each amplifier in the T3 series is:

T3 4600 -2 X 30 A. T3 4320 -30 A T3 2700 -2 X 30 A.

T3 2600 -2 X 25 A. T3 2300 - 30 A. T3 2160 -15 A.

T3 5600 -3 X 25 A. T3 1000 -2 X 20 A.

Caution!

⇒ Bridging fuses or replacing a fuse with one of a higher rating may cause damage to the amplifier and the vehicle's electrical system.

Step 3- Run a remote turn on cable from the switched +12V source you will be using to turn on the system components. This may be a toggle switch, a relay, or your source unit's remote trigger wire, or power antenna trigger wire. Run this lead to the amplifier mounting location. Use #18 AWG wire ____ or larger.

Step 4- Locate a secure grounding connection as close to the amplifier as possible. Make sure the location is clean and provides a direct electrical connection to the frame of the vehicle. Connect one end of a short piece of the same size cable as

the power cable to the grounding point. Run the other end of the cable to the amplifier mounting location.

Step 5- connect the ground cable to the screw terminal labeled "POWER, GND".

Step 6- Connect the power cable to the amplifier at the screw terminal labeled "POWER, +12V".

Step 7- Connect the remote turn on cable to the screw terminal labeled "POWER, RMT".

1.3 Installation- Speaker Connections

Step 1- Run #16 AWG or larger connecting wire from your speakers to the amplifier mounting location. Keep speaker wires away from power cables and amplifier input cables. Use grommets anywhere the wires have to pass through holes in the metal frame or sheet metal. Connect to the speakers according to the type of terminals on each speaker.

Step 2- Strip 3/8" of insulation from the end of each wire and twist the wire strands together tightly. Make sure there are no stray strands that might touch other wires or terminals and cause a short circuit.

Step 3- Crimp spade lugs over the wire ends or tin the ends with solder to provide a secure termination.

Step 4- Connect the wire ends to your amplifier as follows:

SPEAKER TERMINALS

Follow the (A/B/C/D+) (A/B/C/D-), channel and polarity markings, making sure they match the channel and polarity of the connections at the speakers.

MULTIPLE SPEAKER CONNECTION

PARALLEL- Each additional speaker decreases the load impedance for the amplifier. The amplifier delivers more current and works harder.

Caution : impedances lower than 2 ohms may cause damage to your amplifier and is not recommended.

PARALLEL CONNECTION USING 4 OHM SPEAKERS

SERIES- Each additional speaker increases the load impedance for the amplifier. Impedances higher than 8 ohms are rarely used for car audio.

SERIES CONNECTION USING 4 OHM SPEAKERS

1.4 Installation- Self-Bridging, 2+1 Mode

BRIDGED MONO-

Connect a 4Ω ohm speaker to the terminals marked “(+), BRIDGE, (-)”, making sure they match the polarity of the connections at the speakers.

Caution!

⇒ Speaker or multiple speaker loads totaling less than 4 ohms are not recommended for “Bridged” or “2+1 Mode”, and may damage the amplifier.

T3 4600, T3 4320-

Set the “MODE” switch to “2CH, 3CH”, or “4CH” and connect the speakers accordingly. For “3CH” operation, bridge the “C” and “D” channels.

2+1 MODE- (TRI-MODE)

Simultaneous stereo and mono operation, "2+1 Mode", requires a passive crossover to send low frequencies to the mono speaker and higher frequencies to the stereo speakers. The following table lists the component values for a 6 dB/Octave crossover at common frequencies using 4 ohm speakers for stereo and an 8 speaker for mono(subwoofer):

FREQUENCY	INDUCTOR	CAPACTTOR
80 Hz	16 mH 470 uF
100 Hz	7.5 mH 330 uF
120 Hz	7.5mH 330 uF
150 Hz	7.5 mH 220 uF

2+1 MODE WIRING DIAGRAM-

Use 100 Volt, non-polar capacitors, and connect them in series with the stereo speakers as shown in the diagram. Connect the inductor in series with

the mono speaker as shown in the diagram. Be sure the inductor is rated to handle the power of your amplifier.

Recheck all connections before reconnecting the negative(-) battery cable. Insert the correct value fuse in the fuse holder at the battery before attempting to turn on the system.

2. Operation

2.1 Operation- Input Level adjustments

MIN MAX

Adjust the input level for the marked channel(s) with a small screwdriver through the opening marked "LEVEL". Turn CW(clockwise) to increase the level, CCW(counterclockwise) to decrease. Amplifiers will run cooler and produce less system noise at lower level settings.

Consult an experienced installation specialist for assistance in balancing the levels in multi-amplifier systems, or systems with signal processing accessories.

2.2 Operation- Built-in Crossovers CROSSOVER FILTER SELECTION

The T3 series amplifiers have built-in low-pass and high-pass crossover filters for bi-amplifying your system. Select "LPF, FULL or HPF" by moving the position of the slide switch for each pair of channels. "LPF" selects the low pass filter. "HPF" selects the high pass filter. Selecting "FULL" defeats the crossover functions

FREQUENCY ADJUSTMENT

After selecting the crossover function, adjust the low pass or high pass frequency control with a small screwdriver through the opening marked "LP/FREQ." or "HP/FREQ.". Turn CW to set to a higher frequency, CCW to set to a lower frequency.

Turning the "BASS BOOST" switch to "ON" increases the level of frequencies around 45Hz by 12dB.

2.3 Operation- Protection Circuits and L.E.D. Indicators

"POWER." L.E.D. INDICATOR- Provides a visual indication that the amplifier is turned on.

"PROTECT" L.E.D. INDICATOR- Provides a visual indication that a problem exists and the protection circuitry has protected the PROTECT amplifier by shutting it down. Turn the system off and correct the problem before turning the system on.

THERMAL PROTECTION- The amplifier will shut down if its temperature exceeds a safe operating level. The amplifier will remain off until it cools to a safe operating temperature. Exercise care, the exterior of the amplifier may get uncomfortably hot to the touch before shutting down.

OVERLOAD AND SHORT CIRCUIT PROTECTION- The amplifier will shut down if a short circuit condition exists, or if electrical current demands exceed safe levels.

FUSE 15 A

FUSE PROTECTION- A blown fuse indicates a problem that should be corrected before the fuse is replaced. Always replace with the same value fuse. Never substitute a larger value fuse.
