GT5-A3001 CAR AUDIO SUBWOOFER AMPLIFIER OWNER'S MANUAL
Installation Warnings and Tips · Disconnect the negative () lead from your vehicle's battery. · At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas. · Choose a safe mounting location away from moisture. · Make sure there is sufficient air circulation at the mounting location for the amplifier to cool itself. · Mount the amplifier, using the supplied hardware. Specifications · 175W RMS x 1 channel @ 4 ohms and 1% THD + N* · 225W RMS x 1 channel @ 2 ohms, 14.4V supply and 1% THD + N* · 300W RMS x 1 channel @ 1 ohm, 14.4V supply and 1% THD + N* · THD + N: 0.05% (rated power @ 4 ohms)* · Signal-to-noise ratio: 95dBA (reference 1W into 4 ohms)* · Signal-to-noise ratio: 120dBA (reference rated power into 4 ohms) · Frequency response: 10Hz 300Hz (3dB)* · Total peak power: 600 watts * CEA-2006A-compliant 0 Speaker Output Connectors · Connect the subwoofer to these terminals, observing proper polarity. Either + or terminal may be used. Minimum total impedance is 1 ohm. 1 Fuses · Replace only with the same type and rating. 2 Power Input Connectors · +12V: Connect to the positive terminal of the vehicle's battery. 8 AWG wire is recommended. Install an appropriate fuse holder and fuse (40A minimum) within 18 inches of the battery. Make sure the wire is not damaged or pinched during installation. Install protective grommets when routing wires through the firewall or other sheet metal. · GND: Connect to the vehicle's chassis. Refer to the picture below. Factory Bolt Ring Connector Ground Wire 4 Input Connectors (RCA) · Connect to the RCA outputs from the source unit or signal processor. 5 Input-Level Control · Used to match the input level of the amplifier to the output level of the source unit. · See 9 for the adjustment procedure. 6 Protect LED · Illuminated under any of the following fault conditions: battery over/under voltage, short circuit in speaker wires, amplifier is too hot, amplifier's output circuit has failed (DC voltage is present in the amplifier's output). 7 Low-Pass Filter Frequency Control · 12dB/octave low-pass filter, variable from 32Hz to 320Hz. · See A for the adjustment procedure. 8 Power On LED · Illuminated when the amplifier is on. 9 Setting Input Level A Turn Input Level control counterclockwise to 6V (minimim). B With a dynamic music track playing, turn the head unit's volume control to the 3/4 position. C Turn Input Level control clockwise until the bass output is proportionate to the output of the high-frequency speakers, according to your preference. D Input level is now adjusted correctly. A Setting the Crossover A Crossover setting for subwoofers. Note: Acceptable frequency ranges are indicated in gray.
Note: Remove any paint below ring connector.
Star Washer
· REM: Connect to the "Remote Out" lead from the source unit or to a source of switched 12V+ (ACC). 3 Aux Output Connectors (RCA) · Nonfiltered pass-through output. Connect to the input of an additional amplifier.

Amplifier Troubleshooting Guide
1. Status LED on Amplifier not Lit - Head Unit (Source) Turned ON Verify: A. Remote turn-on wire from source to amplifier has proper voltage B. Power (B+) connections at amplifier, terminal blocks, and battery are secure C. Ground (GND) connections at amplifier and vehicle chassis are secure D. Battery B+ fuse (if used) is OK E. Amplifier fuse is OK F. B+ at battery and B+ at amplifier has proper voltage
2. Status LED's Lit, No Output from Speakers in Normal Operating Condition Verify: A. RCA cables from amplifier to source are securely connected B. Volume adjustment on amplifier is correctly adjusted C. Source is ON and playing
3. Engine Noise From Speaker(s) Turn source OFF, Disconnect RCA cables at amplifier. If noise stops, check equipment & cables leading to amplifier. Verify: A. RCA cables are of good quality with no breakage to internal shields B. RCA cables from source to amplifier are not run alongside any power cables
4. Amplifier Output Distorted Music Verify: A. Source output music to amplifier is not distorted B. Source output sensitivity is correctly adjusted
5. Amplifier Shuts Down, Green LED's are Lit - Amplifier is in Thermal Protection Mode Verify: A. Amplifier is mounted with adequate air circulation around heatsinks or vents B. Amplifier is not mounted under carpet or sealed enclosure C. Speakers meet correct impedance for application (mono or stereo hookup)
6. Amplifier Does Not Turn ON, and Red LED is Lit Amplifier (and not Connected to a Shorted Speaker) Verify: A. Speaker crossover (if used) is not defective
