Overview

The Cerwin Vega IOEM88 is an 8-input/8-output line output converter that converts high-level speaker signals from factory systems into RCA-level outputs for aftermarket amplifiers, with multiple load, isolation and signal conditioning options.

Best for

  • Integrating aftermarket amplifiers with factory head units that lack RCA outputs
  • Systems where noise or grounding issues require alternate isolation settings
  • Installations needing independent gain control and clipping indication per channel pair
  • Applications requiring low-pass filtering and bass boost for subwoofer channels

Key points

  • Speaker inputs accept high-level signals up to 400 watts RMS
  • Eight RCA outputs provide channels for connecting aftermarket amplifiers
  • Load select options: 20 ohm, 60 ohm, and 20k ohm to accommodate various OEM head units
  • Ground isolation settings: GND, ISO, and 200-ohm to address ground noise
  • Gain adjustment delivers up to 9.5V RMS output with LED clip indicators
  • Low-pass filter for rear channels filters signals above 250 Hz

Fit and use

Use the IOEM88 where factory systems need conversion to RCA preamp-level outputs for external amplifiers. Select the load option that matches the OEM head unit output behavior, try different ground isolation settings if you encounter noise, and use the clip indicators while setting gain to avoid distortion. Apply the LPF and bass boost when integrating subwoofers or low-frequency channels.

What to know

The IOEM88 offers selectable load and isolation settings because OEM head units can behave differently; selecting the correct options helps ensure proper operation and minimize noise. Clip LEDs provide visual feedback while setting gain but do not replace proper level-matching practices. Compatibility depends on the v…
