Mopar Installation Notes

This installation is for installating a 2001 Mopar Subwoofer in a 2001 PT Cruiser. The 2001 Mopar Subwoofer can not be installed in a 2002 PT Cruiser without modifying the wiring. See the modification procedure near the bottom of this page.

Webmaster Note, Sept 2003 - When this guide was prepared two years ago DC had just released the 2002 model year Cruiser, however there were changes to the OEM audio wiring system. Many 2002 owners were unaware of the wiring change and assumed that Mopars previously designed subwoofer, which was compatible with the 2001 PT, would also work with the 2002 model year PT. New (2002) PT owners purchased this sub, only to discover that the subwoofer installation instructions did not match what they found in their vehicles. Some owners decided not to wait for Mopar to redesign the sub for the 2002 PT, so they designed a "work around" to make the current sub functional in their 2002 Cruisers. We have provided one such remedy near the bottom of this page.

Currently DC manufactures specific model year subwoofers; there's one model for the 2001 PT and one model that works with the 2002-2004 model year Cruisers. The basic installation outlined below is the same for each model year, plus or minus a few variations within the OEM subwoofer installation instructions.

Install parts as shown on illustrations.

To avoid damage to the wiring harness, ensure no contact with sharp edges.

Re-fit panels, ensure components and wiring harness are neatly and securely located.

Use provided torque value for fastening seat belts, and other safety items, or refer to service manual.

Mine came with instructions which made it quite simple. Believe I had it done in just over an hour.

Here are some instructions:

The one difference with mine is reusing the rear panel. You have to grind/drill off the heat welds that holds the pocket.
