Overview
7-Band Parametric EQ with Auxiliary Input
Take full control of your vehicle’s sound system with the Cerwin-Vega EQ780 7-Band Parametric Equalizer with Auxiliary Input, a powerful audio tuning solution designed for car audio enthusiasts and professional installers who demand precise sound shaping and maximum system performance. Built to enhance both factory and aftermarket systems, this 7-band car audio equalizer allows you to fine-tune your music for optimal clarity, balance, and impact.
The Cerwin-Vega EQ780 parametric EQ features seven adjustable frequency bands, giving you detailed control over key audio ranges including bass, mid-bass, midrange, and treble. This level of customization allows you to correct acoustic imperfections inside the vehicle cabin and tailor the sound profile to match your personal listening preferences.
Designed for high-performance systems, the EQ780 provides up to 7 volts RMS output, delivering a strong, clean signal to your amplifiers. This higher voltage output helps reduce noise and improves overall signal clarity, allowing your amplifiers and speakers to perform at their full potential.
The equalizer also includes high-level input compatibility, making it an ideal solution for integrating aftermarket amplifiers into OEM factory head unit systems. Whether you're upgrading a factory stereo or building a custom car audio setup, the EQ780 makes integration simple and effective.
For enhanced bass control, the EQ780 features a dedicated subwoofer level adjustment and selectable low-pass filter, allowing you to precisely manage low-frequency output. This ensures your subwoofer receives only the desired bass frequencies while maintaining balanced sound across the entire system.
The built-in auxiliary input allows you to easily connect portable audio devices such as smartphones or MP3 players, while the Aux/Mains select switch provides quick switching between input sources.

Crossover, Digital Sound Processors, Signal Converter, Bluetooth Receivers - FAQ
Q1: When do I need a line‑output converter (LOC)? How should I choose between IOEM‑series LOC and compact SLMLOCT series?
A: You need a LOC when your factory head‑unit lacks RCA pre‑amp outputs, and you plan to add external amplifiers. It converts high‑level speaker‑level signals into low‑level RCA signals. IOEM models are active units with ground‑isolation and load‑select switches, ideal for complex installations prone to noise. The compact SLMLOCT series fits tight spaces for basic upgrades. Match channel count to your system: pick 2‑in‑2‑out for two‑channel builds, or 4‑in‑4‑out for multi‑amplifier setups.
Q2: What are the main differences between DSP, analogue EQ equaliser, and LOC? Can they be used together?
A: A LOC only converts signal voltage level without tone adjustment. An analogue graphic EQ lets you manually adjust frequency bands as an analogue pre‑stage. Digital DSP offers crossovers, time‑alignment, phase adjustment and parametric EQ via tuning software. They can be combined properly: the factory signal feeds a LOC, then passes to DSP and onwards to amplifiers. Avoid cascading multiple analogue EQ units, as this will raise the noise floor and degrade sound quality.
Q3: Can BTR‑series Bluetooth receivers work without a factory head‑unit? What vehicles are they suitable for?
A: BTR Bluetooth receivers operate standalone without an OEM radio, outputting RCA audio to amplifiers. They work great for UTVs, jet‑skis, motorcycles and off‑road vehicles with no stock head‑unit. They can also add wireless streaming to existing car‑audio systems. Check model specs; select water‑resistant variants for rough outdoor and wet environments.
Q4: Will the CHGLIRCA ground‑loop isolator definitely fix alternator whine noise?
A: The CHGLIRCA isolator suppresses ground‑loop noise, yet it is not a universal fix. When you hear engine‑speed‑dependent whine, first verify all devices are grounded to bare chassis metal, route RCA cables away from power wires, and set the correct load‑select switches on your LOC. Add the isolator only after proper wiring has been completed. It cannot eliminate noise originating from a contaminated vehicle power supply.
Q5: What installation tips apply to DSP processors? Will a DSP drain my car battery?
A: DSP units require 12V constant power, ground and a REM turn‑on signal. Use ACC‑switched power so the unit sleeps automatically at ignition‑off to prevent battery drain. Mount away from heat and moisture. Physical installation is not complete without tuning: configure crossovers, time‑alignment and EQ with official software. Keep input/output gain moderate to prevent signal clipping. Professional shop tuning is recommended if you are unfamiliar with DSP tuning workflows.
