Processors
If you have HiFi, you are well on your way to upgrading!
If you have Base/Stereo, Logic7/Harman Kardon/Top-Hifi, or EPS/Individual, you probably have work to do if you want to start with a clean signal. The latter systems are tapped at the speaker level which means you will need to either:
- Recode your head-unit to Hifi (More links in Base Audio, above)
- Clean/sum the signal
- Use a MOST (proprietary fiber optic) compatible pre-amp. (Logic 7 or EPS only)
Even if you pick option 1, there are still many reasons to add a processor. Here are all the benefits:
- Clean / De-EQ the factory signal
- Sum the factory signal from multiple channels to get a full-range signal
- Time-alignment of individual channels (including for each seating position)
- Automatic level matching/calibration/EQ
- Road Noise Compensation
- Compressed media (i.e. MP3) compensation
Not all processors have every capability, again know your goals. Some of the options:
