Pre-Installation Planning

Complete system planning before starting physical installation. Verify all components are compatible. Check the inventory list.

Required Tools

  • Wire strippers
  • Crimping tool
  • Digital multi-meter (DMM)
  • Heat shrink tubing
  • Heat gun
  • Socket set
  • Screwdrivers
  • Panel removal tools
  • Cable ties
  • Drill and bits

Component Inventory

Ensure the following items are present:

  1. Power amplifier
  2. Audison Bit One DSP
  3. Power cable (OFC)
  4. Ground cable (OFC)
  5. Fuse holder and fuse
  6. RCA cables
  7. Speaker wire
  8. Remote turn-on wire

Amplifier Installation Steps

Follow MECP standards for all installation tasks. Use professional techniques to ensure safety and performance.

Mounting the Amplifier

  1. Identify a mounting location with adequate ventilation.
  2. Ensure the mounting surface is structural.
  3. Avoid mounting directly to vehicle trim or plastic panels.
  4. Use self-tapping screws or machine bolts to secure the amplifier.
  5. Verify the amplifier does not move when force is applied.
  6. Ensure the amplifier does not obstruct vehicle safety systems.

Electrical Infrastructure

  1. Disconnect the negative battery terminal.
  2. Select the correct wire gauge based on current draw.
  3. Route the positive power cable from the battery to the amplifier.
  4. Use a rubber grommet when passing through the firewall.
  5. Install the main fuse within 18 inches of the battery.
  6. Size the fuse according to the wire's current-carrying capacity.
  7. Secure the power cable at 12-inch intervals using cable ties.
  8. Locate a factory ground point or create a new one on the chassis.
  9. Remove paint and debris from the grounding point to reveal bare metal.
  10. Use a star washer to ensure a low-resistance connection.
  11. Keep the ground cable as short as possible, under 18 inches.

Signal and Speaker Wiring

  1. Route RCA cables away from power cables to prevent induction noise.
  2. Connect RCA outputs from the source unit to the Audison Bit One inputs.
  3. Connect RCA outputs from the Audison Bit One to the amplifier inputs.
  4. Run speaker wire from the amplifier outputs to the speakers.
  5. Verify speaker polarity (+ and -) at both ends of the wire.
  6. Use 16-gauge wire for speakers and 12-gauge or 10-gauge for subwoofers.

Audison Bit One Configuration

The Audison Bit One is a 32-bit digital signal processor. It manages signal routing, crossovers, time alignment, and equalization.

Remote Turn-On Sequencing

  1. Connect the source unit's remote output to the Audison Bit One "Remote In" terminal.
  2. Connect the Audison Bit One "Remote Out" terminal to the amplifier's remote input.
  3. This sequence ensures the DSP boots before the amplifiers.
  4. It prevents "pop" noises during power-up.

Initial Software Setup

  1. Connect a laptop to the Audison Bit One using a USB cable.
  2. Launch the Bit One software.
  3. Use the Configuration Wizard.
  4. Define the input type (high-level or low-level).
  5. Identify the speaker configuration (Front, Rear, Sub, Center).
  6. Assign outputs to specific amplifier channels.
  7. Perform the de-equalization process if using a factory source unit.

DSP Tuning Basics

Tuning must be performed systematically. Use a Real-Time Analyzer (RTA) for accuracy.

Level Setting

  1. Set the source unit volume to 75% of maximum.
  2. Adjust the Bit One input sensitivity until the software indicators show a strong signal without clipping.
  3. Set amplifier gains to the minimum setting.
  4. Increase gains until target output levels are achieved.
  5. Use a multi-meter to verify AC voltage at the amplifier outputs if target wattage is known.

Crossover Configuration

  1. Set high-pass filters (HPF) for tweeters and mid-range speakers.
  2. Set low-pass filters (LPF) for subwoofers.
  3. Choose slopes (12dB, 24dB, etc.) based on speaker specifications.
  4. Implement a "half-octave gap" between crossovers to manage frequency overlap.

Time Alignment

  1. Measure the physical distance from the driver's head to each speaker.
  2. Input these distances into the Bit One software in centimeters or inches.
  3. The software calculates the necessary delay for each channel.
  4. This process centers the sound stage for the driver.

Equalization

  1. Use the RTA to measure the system's frequency response.
  2. Apply parametric EQ filters to reduce peaks in the response.
  3. Avoid high-gain boosts to prevent signal clipping.
  4. Use notch filters for narrow resonances.
  5. Aim for a flat or slightly downward-sloping target curve.

MECP Certified Installation Tips

  • Always use a digital multi-meter to check for 12V power and ground continuity.
  • Label all wires at both ends for identification during troubleshooting.
  • Use ferrules on wire ends before inserting them into terminal blocks.
  • Ensure all connections are mechanically sound and insulated.
  • Re-check battery voltage before and after the first power-up.
