There comes a time when you surpass the standard 4 speakers, a stereo and an amplifier. Or maybe you’ve surpassed your factory system and you’d like to go straight to a DSP system setup. But, Should you use a DSP with your factory head unit or upgrade to an aftermarket head unit? Let’s take a look at the pros and cons of each option.
Using a DSP with a factory head unit
Pros:
- Cost-effective: You can still get improved audio quality without having to purchase an aftermarket head unit, which can be more expensive.
- Retains factory appearance: If you’re concerned about maintaining the original look of your car’s interior, adding a DSP to the factory head unit can help achieve that.
- No need to rewire: You won’t need to rewire your car’s audio system, which can save time and effort.
Cons:
- Limited processing power: Factory head units often have limited processing power, which can limit the potential improvements from a DSP.
- Limited compatibility: Not all factory head units are compatible with DSPs, which can limit your options.
- More complex installation: Installation may be more complex and require additional wiring and customization.

Using a DSP with an aftermarket head unit
Pros:
- More processing power: Aftermarket head units typically have more processing power, which can allow for more advanced audio processing.
- Greater compatibility: Aftermarket head units are often designed to work with DSPs, making compatibility less of an issue.
- Greater audio customization: With an aftermarket head unit and a DSP, you can have greater control over audio customization, including crossover settings and time alignment.
Cons:
- More expensive: Upgrading to an aftermarket head unit can be more expensive than adding a DSP to a factory head unit.
- May require rewiring: Installation of an aftermarket head unit and DSP may require rewiring of the audio system, which can be time-consuming and may require professional installation.
- Changes the appearance of the dashboard: If maintaining the factory look of the dashboard is important, an aftermarket head unit may not be the best option.
Frequently asked questions:
Q: Can a DSP improve the audio quality of a factory head unit?
A: Yes, a DSP can improve the audio quality of a factory head unit, but the level of improvement may be limited by the processing power of the head unit.
Q: Can I use the same DSP with a factory head unit and an aftermarket head unit?
A: Yes, DSPs are often designed to be compatible with both factory and aftermarket head units.
Q: Do I need an aftermarket head unit to use a DSP?
A: No, you can still use a DSP with a factory head unit, but the level of improvement may be limited.

Installing A DSP into a Factory system Vs an Aftermarket System
When it comes to installation needs, using a DSP with a factory head unit may be simpler as you won’t need to rewire the system. However, adding a DSP to an aftermarket head unit may provide more flexibility and customization options, but may require rewiring the system. Additionally, if you’re not familiar with car audio installation, it’s recommended to seek professional help to ensure the installation is done correctly and safely.
In conclusion, both options have their pros and cons, and the decision to use a DSP with a factory or aftermarket head unit will depend on your individual needs and preferences. Keep in mind that regardless of which option you choose, proper installation and calibration are crucial to ensure optimal performance and sound quality.
