Introduction We thank you for purchasing our amplifiers. Your decision to be part of something different is what we strive for. Our products reflects who we are, going to the extent to deliver you our finest comes natural. to upgrade the stock electrical system. Ensure the system is in accordance with the full performance of the amplifier. Better Bass Better Bass is our philosophy of adding something extra. Keep in mind that continious exposure to SPL above 100 dB can seriously damage your hearing.
Design features Mono Circuit Configuration: Frequency Response: Signal to Noise Ratio: Input Sensitivity: Crossover Circuit: Low Pass Crossover: Subsonic Crossover: Damping Factor: Bass Boost Frequency: Bass Boost: Remote Control: Power Terminal Gauge: Fuse Rating: Dimensions: HI-EF Class D 15 Hz ~ 250 Hz > 100 dB 6 V ~ 0.2 V 24 dB / Octave 35 Hz ~ 250 Hz 35 Hz > 300 0 dB ~ 9 dB 35 Hz ~ 100 Hz Included 0 GA x 1 150A 9.84’’ x 2.52’’ x 13.
Panel layout Mono INPUT BASS BOOST POWER & PROTECTION INDICATOR LPF (LOW PASS FILTER 35 Hz ~250 Hz, 24 dB/oct) RCA signal input for Left & Right channel. A minimum of 0.2 v input signal is required for correct operation. Variable signal boost of the BASS FREQ chosen with 0 dB ~ 9 dB. Power LED, blue light shows correct operation, Protect LED, red light shows general malfunction, faulty connection or thermal protection. Adjusts the cut off point for the low pass crossover at the frequency chosen.
Panel layout Head unit Mono GROUND* 150A (External fuse) * Keep ground as short as possible, no longer than 20” (50 cm). BATTERY GND (GROUND CONNECTION) + 12V (POWER CONNECTION) Connects to the vehicle’s chassis. Keep as short as possible (< 20” / 50 cm) Use minimum 0 Ga cable for optimal conditions. REM (REMOTE) Connects to switched +12V from the headunit. speaker (speaker output) Connects to the speaker(s) leads. Ensure polarity is correct on the speaker and connect to the corresponding output.
Installation Installation considerations If you choose to install the amplifier by yourself, please read the entire owner’s manual carefully. 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.
Wiring layout +12V, GND, REM connection, Speaker connection Head unit Mono GROUND* 150A (External fuse) * Keep ground as short as possible, no longer than 20” (50 cm). BATTERY We recommend to use minumum12 Ga speaker cables to acquire the intended performance. Run the speaker cables from your speakers to the amplifier’s mounting location. Ensure these are ran separately and away from high current cables and if possible the RCA cables as well.
Speaker Wiring Diagram - single amplifier Mono Speaker impedance 1 Ohm ~ 8 Ohm Loads under what is specified will cause excessive heat & the amplifier will reach thermal at a faster rate & will eventually go into protect. Impedance load under 1 ohm is not warranted! Speaker Impedance 1~ 8 ohm Strapped speaker wiring - Master / slave Linking or strapping makes 2 amplifiers work as a single amplifier. This configuration will near double the rated output power.
Strapped speaker wiring - Master / slave 1 Linking or strapping makes 2 amplifiers work as a single amplifier. This configuration will near double the rated output power. Follow the instructions carefully as it can cause harm to your system if done incorrect. Speaker impedance 2 Ohm ~ 16 Ohm Loads under what is specified will cause excessive heat & the amplifier will reach thermal at a faster rate & will eventually go into protect.
Strapped Control panel setting Master / slave 1 Head unit L master slave 1 To link the master and slave 1 amplifier RCA connection follow the steps below. Keep in mind amplifiers needs to be switched off, linking the amplifiers when switched on may cause harm and can void your warranty! Step 1. Connect RCA from Head Unit / output source into master amplifier RCA input. If only one output is available, then use a Y-split to connect both L & R. Step 2.
Control panel setting Master / slave 2 / SLave 2 Head unit L master slave 2 slave 2 To link the master and slave 2 amplifiers in daisy chain mode follow the steps below. Each slave 2 will be controlled by the master’s control panel, but the speakers must be connected individually to each amp. The daisy chain is a true benefit when you have multiple speakers and amps. Step 1. Connect RCA from Head Unit / output source into master amplifier RCA input.
Crossover - boost settings Mono . Low pass, Bass freq, Bass Boost The low pass crossover is 24 dB / oct. Setting it at 80 Hz will then have the signal cut off with 24 dB at 40 Hz (1 octave). To ensure accuracy for the individual crossover frequency the pot feature 41 clicks, each with a corresponding frequency. The same is valid for the Bass frequency and Bass boost settings, which also features 41 clicks. CLick settings for LPF - Bass Boost - Bass Frequency LPF 1. 35 Hz 2. 35,06 Hz 3. 35,06 Hz 4.
Troubleshooting The protection circuits of the amplifier prevents severe damages from faulty conditions & improper use. 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).
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. Items not installed by authorized dealers will be warrantied for 30 days from the original purchase. Original sales receips must be accompanied with all returns.
