Frequently Asked Questions

• Can I install the DEQ-2000A without removing my factory stereo? Absolutely! The DEQ-2000A is specifically designed to work with your factory head unit using speaker-level inputs. It processes the signal from your existing stereo and upgrades the sound quality without requiring any replacement of factory components. Optional speaker line input cables make installation even easier.
• Do I need professional installation, or can I install it myself? While professional installation ensures optimal results, the DEQ-2000A is designed for ease of installation with its compact size (fits under most seats) and flexible input options. Basic car audio installation experience is helpful, but the included documentation and online resources make DIY installation achievable for enthusiasts with moderate technical skills.
• How do I tune the DSP - is it complicated? Not at all! The free DSP Controller app provides an intuitive visual interface on your smartphone (iOS or Android) that makes tuning straightforward. You can use pre-set EQ curves matched to common vehicle types, then fine-tune while listening. For more detailed control, the PC software displays all functions on one screen for professional-level adjustments.
• Will this work with my Apple CarPlay or Android Auto? Yes! The DEQ-2000A is fully compatible with both Apple CarPlay and Android Auto systems. It processes audio from these sources seamlessly while maintaining factory navigation audio mixing, so GPS voice guidance automatically attenuates music without interrupting your connection.
• Can I add a subwoofer to my factory system with this DSP? Definitely! The channel summing feature allows you to create a dedicated subwoofer output by combining channels, even from a factory stereo signal. With 6 RCA pre-outs, you can easily connect a subwoofer amplifier and integrate bass into your system with proper crossover settings and time alignment.
• What's the difference between this and just adding an amplifier? A standard amplifier only increases power. The DEQ-2000A is a complete audio processor that corrects acoustic problems in your vehicle through time alignment (compensates for speaker positioning), equalizer (corrects frequency response), and crossover management - PLUS it includes 160W of amplification. It's the "brain" that makes your entire system sound dramatically better.
• How much power does the built-in amplifier provide? The DEQ-2000A delivers 160W nominal power (4 x 40W per channel) with 320W maximum power output. This is sufficient to drive factory or aftermarket speakers directly, or you can use the 6 pre-outs to connect external amplifiers for higher power applications while still benefiting from the DSP processing.
