【Wiring Routing Changes for Switching an Existing Car Audio to DSP Connection / Trunk Extension Work】

If you want to add a DSP to a car audio system that was already installed by another shop, simply preparing the equipment may not be enough.

To change from a connection that uses the existing passive network to a system that uses DSP, you need to check the current wiring and connection method and, if necessary, rewire. If you are installing the DSP in the trunk, we will also perform wiring extension work from the front of the cabin to the trunk.

Using a DSP makes it easier to adjust the volume balance and the way speakers interact to match the interior of the vehicle. However, which wiring should be kept, where it should be rewired from, and what to do with the existing passive network will vary depending on the vehicle and the current installation details.

Even for vehicles installed by another shop, we first confirm the current system configuration and the wiring condition. After checking the processing and connection methods in parts that you can’t see, we will work together to determine whether it’s necessary to redo everything or to make only the required changes while taking advantage of the parts that can still be used.

When extending the wiring to the trunk, it’s important not just to make it longer, but to perform the work with consideration for how the vehicle will be used and for future maintenance. If you want to add a DSP but don’t know how much of the current system needs to be changed, please consult us while we look at the actual vehicle.

Let’s review the installation details once and consider a realistic connection method that fits your current vehicle. If it were me, I would avoid guidance that could change later; I would first properly confirm the current wiring and system configuration before moving forward.
