Stereo Door Speakers

Recommended Posts

Posted (edited)

Doing some small fixes on 99 boxster base after finally correcting a CEL issue. My door speakers don't work (yes w fader full to rear) I tested the door speakers on their own and they work so not the speaks. I then used jumpers between output plug and head unit to troubleshoot head. The dash worked as they should door didnt  so I jumped dash output from head to door speakers and dash speakers were sounding ..... now on the pinout I'm assuming front means dash and rear is door OR I'm totally incorrect and the fronts are in series and door and dash are considered front and rear speakers are only included in some sort of upgrade cause I don't have speakers in the storage bin behind the seats. There is a poweramp in the frunck. thanks v....OK They do work as faint sudo-subs....awful. So I assume the rear fader is for an additional set of speakers.

Your door speakers are NOT rear speakers.  They are woofers, and your auxiliary amp contains a crossover so they receive only bass frequencies.  For rear speakers, you install the rear shelf system and connect those speakers to the actual rear speaker outputs that already exist on your radio.  Better yet, obtain a 6X40 auxiliary amp from a 996/911 Cabrio, and wire the rear speakers to that.  When you do either, you will then have expected fader operation.

I wound up figuring that out by putting my ear up to the doors. I'm not sure if I have 2 extra channels on that amp. I tried to jump the rear outs from the amp(by looking on the schematic) to the dash speakers reading from the pin out but didn't get anything. V

You don't.

 

Two solutions ...

 

1.  Radio has speaker out connectors as well as amp out connectors.  You can use  the direct to speaker outputs for your rear speakers.

 

2.  Find a 6X40 amp from a 996/911 ... it will have working rear speaker outputs, and FYI your radio to amp wiring already has the rear outputs in the harness and connector.  Note:  there are 2 versions of the 911 amp ... coupe and cabrio.  Cabrio is better for Boxster.
