From the first time we talked to the delivery of my order

Excellent!

I was looking to replace my Ground Zero sub but could not find a local shop that had any in stock. I did a search and came across TDS Car Audio. I found the exact subwoofer I was looking for and received it fast ( even though I am out of state). My husband installed it and it sounds great. Thanks TDS!!
