I just bought a 2004 WRX and wanted to consider my options for subwoofers and wanted to know (before I rip apart my dash) if the OEM head unit has a preamp output etc. Any pics of that bugger would be clutch.
No preamp outs. Get a sub that accepts speaker-level inputs, use a line-level converter, or replace the HU with something better (a good idea in any case).
