Quadratec Sony plug n play problem/solution

Maybe you guys already figured this out - took me almost a year. I got a Sony Plug N Play setup from Quadratec. Great idea - comes with the dash adapter, prewired harness, and radio (Sony CDX-GT570UP). Easy install, but the subwoofer didn't work. I messed around with it a few times pulling everything apart and putting it all back together, checking continuity, pulling apart the console to get to the subwoofer, checking and rechecking that the blue wire went to the blue wire to run the subwoofer, checked the fuse, etc. Finally took a close look at the Quadratec wiring harness and compared it to the unused Sony harness in the box. The Q harness has the blue wire (antenna/subwoofer) in the 4th from the left position on the BOTTOM row. The Sony harness has the blue wire in the 4th from the left position on TOP row. I build a little jumper wire on the Q harness to connect the 4th top row position to the blue wire in the bottom position, and now I have a working subwoofer (such as it is). Not thumping bass, but a much much richer sound.


02 TJ Sahara 4.0 5 spd, 3.73, Dana 44 rear, 2.5" lift w/ Bilstein shocks, 33x12.50

Greetings from a 2002 TJ owner in Kalispell! Just installing this tonight. . . . and before I put my dash back together, thought I'd check the old forum to see if I was missing anything. . . I am game to try anything myself, but I know what I don't know, which is a lot . . . is the subwoofer you are refering too in your console? My 2002 is a mid year build, as I actually have a 2003 color. . . well low and behold, when I start installing I don't have the braided ground wire, mine is the "2003" ground built into the harness set up. . . just wondering if I have everything hooked up correctly before I put the dash back together. It plays, but I thought the sound was a bit "less robust" than the original unit. . . My heep is completely stock so I know nothing else has been messed with as far as the stero goes. . . thanks.

There was a wire harness revision a while back. I found this out when I swapped my KDC-X591 for a newer, better KDC-X993 & received another wire harness adapter. I created a thread documenting it, but it seems to have disappeared...

Anyway, it could be that the OP of this thread received a plug & play harness that was the first run harness (dark grey plug pictured below), which had everyone hooking up the trigger wires by matching the color coating (which was wrong). Unfortunately, that left a lot of people who only had a working subwoofer when the radio was the selected source (no CD/USB/AUX functionality). This is because the first run of harness adapters had a blue wire, which is usually used for the power antenna trigger on most (but not all) aftermarket head units, instead of a blue wire with a white trace (blue/white).








Pictured below is the pinout for a 2005 TJ. While the wire colors might have changed, I'm pretty sure the pinouts have not. If your OEM harness has the 22 pin plug, confirm that your new head unit's amp trigger wire (probably labeled remote turn on/amp turn on/amp) is connected to the cavity 13 location of the factory harness.

For some people (depending on brand of head unit), the first wire harness adapter would have a blue (harness adapter) to blue/white (radio harness) connection.








If you post up what make/model head unit you're installing, I can look it up to confirm the trigger wire for the amp.


Hope this helps.
