Yes; any head unit with pre-amp outputs can be wired to drive the OEM speakers. If you search this forum you can find how to make an adapter cable harness (more typically process is to go from OEM head to after-market amps, but process is essentially the same, just with the appropriate wiring changes. I have made both)Originally Posted by midlifecrisis
Yes, get a head unit with pre-amp outs (most do these days). If you have a head without pre-amps and only speaker outs, you can still use it but must add an attenuating device (see PacAudio or PIE or similar)As I understand it, the amps are in the speaker units, and therefore I assume they would need a line-level (un-amplified) signal.
No - absolutely none, nada, zippo!Also, are there aftermarket head units that don't require modifying the OEM console?
See my post in your other thread to check if you really have a problem with your OEM head unit or the amps.
