Default Audio install question (XSVI-2004)

So I've wired everything up per the provided instructions, but I've got an "extra" plug/harness from the OEM loom and basically non existent bass.

Any insight on what this plug is for and where it goes?

There's definitely something wrong. Have you checked if the 8-inch door subwoofers are working? By your description, it seems they are not.

Make sure 9-pin connector from interface is plugged to connector C4 from OEM radio harness. Also, take a look at Fuse 28 and Relay 45.

OEM Connector C3 is not used.

Let us know what you find.

What I found is I am a total idiot....by adjusting the gain on the 4 channel box, I magically discovered my lost bass. Now that the gain issue is ironed out...it sounds much better.

Just ordered the JBL speakers for the doors and hatch, so hopefully it'll sound even better shortly!!!!
