Need to know how to bypass a Bose amp? Large speakers can be wired to bypass a smaller Bose amp to provide a great sound effect, especially when listening to low music. For such a purpose, subwoofers work very well. However, subwoofers need a better signal strength compared to other types of speakers installed in your vehicle. This makes it important to have some kind of amplification to get the best performance and sound from the subs. This can be done by bypassing the way the subwoofer was installed in the vehicle by getting powered-subwoofer. These subs have amps pre-built into them, which enables you to connect them directly with the stereo inside your vehicle instead of using a Bose amp.
To bypass a Bose amp, you will need:
- A powered subwoofer
- A wiring kit for the amplifier
- Pliers or a wrench
- A wiring harness adapter
- To bypass your Bose amp, first, using pliers or a wrench, take off the bolts of each of the battery terminals. Take off the negative battery clamp by disconnecting it from the negative battery post. Keep it away until it is required again.
- Take the ring terminal of the wiring kit and attach it to the lead post of the positive battery. Attach it with the positive cable clamp and tighten using the wrench. Take out the fuse of the ring terminal kept in the fuse holder.
- Connect the electrical supply with the ring terminal and circuit the power supply cable through the firewall inside the vehicle cabin. Once done, the cable should come out from the footwell. Route the cable out of the footwell and to the back of your vehicle, towards the cargo area (or the trunk in the case of cars).
- Take out the stereo from its dashboard dock. Make sure you check your instruction manual for the proper steps to carry this out. Disconnect the wiring of the stereo from the back panel. Attach the lead connectors of the wiring harness to the outlets placed on the back panel of the stereo.
- Connect the wiring of the stereo with the wiring harness lead connectors. Connect the lead connectors of the turn-on and the signal to the wiring harness adapter. Check the instruction manual for the exact locations for connecting the wiring. The harness may also have color-coding to indicate the exact locations.
- Route the turn-on lead wires and the signal from the rear down towards the floor. In case there is an option, run the cables in a manner such that they come out from the passenger side.
- Run the turn-on lead wires and the signal from the back of your vehicle to the side opposite to that of the power supply cable. This is to avoid the interference emitted by the electrical supply which generally affects the signal when run simultaneously.
- Keep the powered subwoofer inside the back cargo area or the trunk of your vehicle. Connect the powered subwoofer to the power supply. Connect the turn-on lead wire and the signal cable as indicated on the subwoofer.
- Attach the grounding cable of the amplifier wiring kit with the subwoofer using screws or a bolt in the back of your vehicle. Use a bolt which directly connects to the frame of the vehicle for better grip.
- Keep the grounding wire back towards the negative battery lead. Attach the cable with the post using the wrench. Keep the fuse inside the fuse holder of the ring terminal, and close the lid.
These steps will allow you to bypass your Bose amp and get the most out of your car's sound system.
