FS: JL Audio CleanSweep CL441dsp

4-channel in / 4-channel output high-end car audio OEM integration processor. High-level and low-level signal inputs. Automatic 30-band DSP equalization. This is a current model in the JL Audio product line-up.

Moderator's note: OEM integration processors are helpful for owners of newer cars who want to improve sound quality but at the same time keep their OEM head units due to their integration with cars' HVAC controls / navigation systems and also aesthetics.

What the CleanSweep does, apart from bringing the speaker-level signals down to line-level, is to automatically equalize the OEM head unit's signal output to provide a flat frequency response, through the automatic 30-band DSP equalization. The clean output signals could then be fed to high-end power amps and speaker systems/component drivers.

This is a used item.
Price:  S$200

FS: Rockford Fosgate 3sixty.2

6-channel in / 6-channel output high-end car audio OEM integration processor. High-level and low-level signal inputs. Additional 2-channel AUX input. Individual 31-band (FL/FR), 27-band (RL/RR/C) and 10-band (sub) EQs, and individual high/low/band/by-pass filters.

Moderator's note: OEM integration processors are helpful for owners of newer cars who want to improve sound quality but at the same time keep their OEM head units due to their integration with cars' HVAC controls / navigation systems and also aesthetics.  You need an Android phone (or if you still have Palm OS phone) to do initial configuration.

What the 3sixty.2 does, apart from bringing the speaker-level signals down to line-level, is to allow a high degree of customization through individual input channel levels, EQs and filters.

The unit also provides Time Alignment, with individual channel adjustable Delay. The clean output signals could then be fed to high-end power amps and speaker systems/component drivers.

This is an older model, so clearing space to make room at a low price.  I have new-old-stock (NOS, meaning item inside the open box is still shrink-wrapped) as well as used one.

Price:  NOS S$250, used S$200
