These parts were received on a replacement quarter panel we got for a vehicle we were repairing. The car we are repairing does not have them so there was no need in using these. We have not tested to see if they work. YOU GET WHAT YOU PAY FOR! NO GUARANTEE IF THEY WORK! NO REFUNDS. From my understanding the box is the most sought after piece because the subwoofer in the box can be replaced. However all 3 items will need to go together. |
