This listing is for a set of new Delco car speakers (part # 16197665).  These come in the factory box and each set contains 2 4x6 speakers.  Each set of speakers will also come with a short wiring harness that plugs into the 2 speaker and combines the for one plug-in.  This harness will not be attached to the speakers but will be loose in the box for you to use if desired. The mounting depth of these speakers is 2 7/16" (this is the distance from the back of the magnet to the front of the face).These are genuine Delco parts so you can be assured of their quality.  The shipping on this auction will be $8.49 for Priority Mail.  If you purchase more that 1 set of speakers, the shipping will be as follows: 2 set-$14.49,  3 set-$18.48, 4 set-$22.00, 5 set-$25.00, and $3 for each additional set after five.  If you purchase multiple sets, please wait to pay until I send you and invoice reflecting the correct shipping cost.  If you would rather pay at the time of purchase,  I will refund you the difference in shipping.  I am not sure what vehicles the speakers are for, but feel free to contact me with any other questions you may have.  Thanks for looking and have a great day.
