Before you start your installation, please take all steps into consideration. If in doubt, please go to www.b2audio.com for authorized distributors / dealers that will be able to configure your set up & ensure the warranty of your amplifier. Preparation Disconnect the negative (-) battery cable before mounting or making any connection. Check the battery & alternator ground (-) connection. Make sure they are properly connected / dimensioned & free of corrosion. Before selecting a mounting location for the amplifier, please take cooling & safety into consideration. Avoid areas with excessive vibration & up side down installation which can damage the amplifier. Our amplifiers have been designed with a good heat dissipation heatsink. In order to avoid excessive heat from the amplifier, it is recommended to find a mounting location that allows for vertical positioning of the heatsink fins. For safety purposes, install the amplifier in a dry and well ventilated location and make sure no cables or other harness of the car is interfaced with the mounting location or will present a hazard to the car’s cables, control cables, fuel lines / tanks, hydraulic lines or other components of the vechicle. Power connectors 12V (Power connection) Before mounting the amplifier, disconnect the negative (-) wire from the battery to protect any accidental damage to the amplifier or the audio system. The amplifier is equipped with 4 AWG power & ground terminals. It is crucial that all terminals are used with the adequate cable to ensure correct operation. Connect the power cables to the power terminal labeled as +12V. The Quattro is equipped with fuses, but the power cable still has to be fused at the battery. Connect one end of the fuse holder to the power cable and the other end of the fuse holder to the positive battery terminal within 20 cm / 8’’ 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. Make sure that the fuses and the fuse holder is adequate for the desired application. Once all cables (pos & neg) are connected to the amplifier, then reattach the negative wire to the battery (final step). GND (Ground connection) Locate a secure grounding connection as close as possible to the amplifier. Make sure the location is clean and provides a direct electrical connection to the chassis of the vehicle. Connect one end of an equal sized cable as the positive cable to the location of ground. It is important that the ground cable is as short as possible, but no longer than 50 cm / 20’’ at maximum. Run one end of the cable to the grounding point. Run the other end of the cable to the mounting location. Connect the ground cable to the terminal labeled as GND. REM ( REMOTE CONNECTION ) Run a remote turn on cable from the switched +12V source. This may be a toggle switch, a relay, the source unit's remote ouput cable or power antenna trigger cable. Connect the remote turn on cable to the power terminal labeled as REM. 6 Wiring layout Quattro CH1 CH2 HPF TLA SWEET LIKE DANISH CH3 4V 0.2V 4V 0.2V FULL TLA HPF CH1/2 LPF CH4 REMOTE (CH 3 + 4) Remote control (optional) Head unit Speaker connection CH2 4 ch stereo CH1 CH2 CH1 Speaker impedance 2 ~ 8 Ohm CH4 CH3 CH3 CH4 7 Speaker connection CH2 2 ch stereo + 1 ch mono CH1 CH2 CH1 CH4 CH3 Speaker impedance 2 ~ 8 Ohm Speaker impedance 4 ~ 8 Ohm Speaker connection 2 ch bridged CH2 CH1 CH4 CH3 8 CH1 Speaker impedance 4 ~ 8 Ohm CH2 Speaker impedance 4 ~ 8 Ohm Wiring layout Active Mode (tla) CH1 CH2 HPF TLA SWEET LIKE DANISH CH3 4V 0.2V 4V 0.2V FULL TLA HPF CH1/2 LPF CH4 REMOTE (CH 3 + 4) ACTIVE MODE (TLA) CH1 & CH2 RCA input only.

The protection indicatior will switch on due to short circuit connection & speaker overload, thus the amplifier will be turned off. Prior to inspecting the occurred problem, turn all levels down & all power off, then carefully check the installation for wiring mistakes, shorts or faulty ground (GND). If the amplifier shuts down due to excessive heat, the protection indicator will light up; please allow time for the unit to be cooled off. Before removing your amplifier, refer to the list below and follow the suggested procedures step by step. If not at ease, contact an authorized installer which can assist you. AMPLIFIER DOESN’T TURN ON Measure voltage on the +12V terminal. Ensure that the remote terminal has min. 13.8 V DC remote connection. Recheck the ground (GND) connection. Inspect the in-line fuses. Check the protection LED is not on. . PROTECTION LED IS LIT ONCE THE AMPLIFIER IS TURNED ON Check shorts on speaker wires & the connected load / impedance. Check power cables & GND. Disconnect the speaker cables and reset the amplifier. High / Low voltage, operation voltage is 10 V ~ 15.5 V. Voltages beyond this will cause the amplifier to go into protect. FUSE BLOWING Measure the speaker impedance & that it is in accordance with the configuration. Inspect the power cable for shorts along with vehicle chassis. OVERHEATING Measure the speaker impedance & that it is in accordance with the configuration. Check speaker shorts. Ensure airflow around the amplifier is sufficient & that the amplifier is not installed in areas of excessive vibration & upside down! AUDIO OUTPUT INSUFFICIENT - DISTORTED SOUND Ensure that the gain settings on the amplifier is matched with the output level of the head unit. Adjust the head unit volume. Check speaker shorts. Adjust the crossover frequencies in accordance with the setup. If no output at all, check the RCA connections & the cable itself. TURN ON THUMP Disconnect the signal input to the amplifier, then turn it on and off. a) If the noise is cancelled, then connect a delay turn on module on the REM wire running from the source unit to the amplifier. b) Use another 12V source for REM lead to the amplifier. If the noise is cancelled, use a relay to isolate the amplifier from the turn on thump. HIGH HISS-ENGINE NOISE IN SPEAKERS Ensure that all signal transferring wires (RCA, speaker cables etc) are kept seperately / away from the power and the ground wires. Bypass all electrical components between the Head unit and the amplifier. Connect the Head unit directly to the amplifier’s input. If the noise is eliminated, the unit bypassed is the one causing the noise. Remove the existing ground wires for all electrical components installed. Ensure that the point of ground is 100% metal which has been grinded free of rust, paint etc. Replace the ground cable from the OEM battery / alternator and ensure it is grounded accordingly. Test the battery and alternator load (can be carried out by a professional). Ensure that the vehichle’s electrical system is in a good condition, this includes distributor, alternator, spark plugs / wires, voltage regulators etc. Feel free to visit us at: www.b2audio.com & www.facebook.com/b2audio 10 LIMITED WARRANTY INFORMATION B2 audio offers a limited warranty under the following terms: The product is to be free of defects in material & workmanship under normal use for a period of 1 year from the date of the original purchase, when installed by an authorized dealer.
