HIFONICS BRX5016.5 (01) PDF Document

Many new and factory radios require a reset code when disconnected from battery power. This is an anti-theft feature. Before unplugging power, you must determine if your radio/source unit requires a reset code. Check the operation manual for your vehicle or contact the dealer. Be prepared to disarm your vehicle’s alarm and to enter your radio/source unit code after re-connecting the battery.

It is critical to use the proper power and ground cable and fuse size for your HIFONICS BRX5016.5 amplifier. The recommended sizes are as follows:

Always use high quality copper cable. This model requires an external fuse.

Follow these steps to install your HIFONICS BRX5016.5 amplifier:

Step 1. Disconnect negative battery terminal: Place the terminal in a secure position so that it won’t accidentally contact the negative battery post.

Step 2. Run Cables: Properly route power, speaker, and RCA cables through the vehicle.

Step 3. Mount Amplifier: Choose a mounting location that will provide adequate air ventilation. Mount the amplifier to a secure surface. Do not mount the amplifier upside down.

Step 4. Chassis Ground: The chassis ground connection is critical. Choose a location close to the amplifier. Completely scrape away paint from the area to expose bare metal. Use a nut and bolt if possible. DO NOT USE AN EXISTING FACTORY BOLT.

Step 5. Negative Power Connection: Attach the chassis ground cable to the amplifier negative terminal. It is important to make sure this connection is very tight.

Step 6. Remote Turn-on Connection: Attach the remote turn-on wire to the amplifier remote output of the source unit.

Step 7. Positive Power Connection: Attach the main power cable to the amplifier +12V terminal. The cable must run directly to the battery and be properly fused and very tight.

Step 8. Signal Input Connection: Connect the RCA cables to the INPUT connectors. The OUTPUT can be used to provide input for a second amplifier.

Step 9. Level Control: Before initial power-up, turn the LEVEL control completely counter-clockwise to its minimum setting.

Step 10. Speaker Connections: Connect the speaker cables to the speaker output connectors. Follow the speaker configuration diagram that best fits your system (Stereo, Bridged, Monoblock).

Step 11. Positive Battery Connection: Connect the power cable to the positive battery terminal. The power cable must be fused within 18 inches of the battery terminal.

Step 12. Re-connect Negative Battery Terminal: Re-connect the negative battery terminal, making sure it is securely tightened.

Connect the speaker cables to the speaker output connectors on the HIFONICS BRX5016.5 based on your desired configuration.

Stereo: Connect the left speaker’s positive (+) wire to the LEFT + terminal and its negative (-) wire to the LEFT – terminal. Connect the right speaker’s positive (+) wire to the RIGHT + terminal and its negative (-) wire to the RIGHT – terminal.

Bridged: To bridge two channels for a single speaker, connect the speaker’s positive (+) wire to the LEFT + terminal and the speaker’s negative (-) wire to the RIGHT – terminal. The terminals used for bridging are typically marked on the amplifier.

Monoblock (single woofer): Connect the woofer’s positive (+) wire to one of the positive (+) SPEAKER OUTPUT terminals and the negative (-) wire to one of the negative (-) SPEAKER OUTPUT terminals.

Monoblock (multiple woofers): Connect the woofers according to their wiring configuration (series or parallel) to the positive (+) and negative (-) SPEAKER OUTPUT terminals.

Setting the level is a critical step to ensure your HIFONICS BRX5016.5 is properly adjusted to match the signal output level of your source unit. This is not a volume control. Follow these steps:

1. If possible, with the source unit off, confirm that the primary volume control is turned down (counter clockwise).

2. Turn on the source unit (CD or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “0” adjustment. Make sure that the green LED on the end of the amplifier is illuminated.

3. Play a clean musical selection of which you are very familiar. A CD is preferred. Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.

4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.

5. Increase the amplifier level (clockwise) until distortion is heard, then back the level down (counter clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple amplifiers.

A – Input Mode: This switch will “sum” or combine the right and left channel signals in the MONO position to improve bass performance. Select MONO only when the amp is being used for subwoofers. Otherwise, use STEREO.

B – Xover Mode: This switch sets the type of crossover that will be active (FULL, HP, LP). 4-channel models will have two switches, one for each set of channels.

C – High Pass Adjustment (HPF): This control will limit the output below the selected frequency (60Hz to 1.3kHz). This is typically used to protect midrange and high frequency speakers from damage and to allow a smooth transition from a subwoofer.

D – Low Pass Adjustment (LPF): This control will limit the output above the selected frequency (35Hz to 250Hz). This is used to allow a smooth transition to the higher frequency speakers.

E – Bass Boost: This control will increase the power output at 45Hz (from 0 to 10dB) for more pronounced bass. Exercise caution when using this control. Increase the level in small amounts until distortion is noticed, then back off a little.

F – Remote Level Control: Some models include a bass remote. Avoid adjusting the bass remote while operating the vehicle.

G – Level Setting: This control matches the amplifier’s input sensitivity to the source unit’s output voltage (from 9V to 0.2V). It is not a volume control and must be set correctly to prevent distortion and damage.
