  1. 2009 chevy cobalt LT with full kenwood system. Double din kenwood mutimedia receiver, 6.5″ 3-way speakers and 6″ x 9″ 3-way speakers, (2) MTX 5500 10-inch subwoofers powered by a kenwood 8105d amplifier!! thanks for the diagrams.

  2. I used your diagram to repin my harness and everyhting works great, except my factory sub. How is the sub wired to get power? or do i need to run RCA wires from the sub to my new stereo. If it matters i have an 05 cobalt ss pioneer sound system factory with pioneer headunit deh p6000ub

  3. this diagram should work for all chevrolet Cobalt models due to standardizing the company back in the ’90’s. LOVE CHEVROLET!
