wasn't too bad. Prob took around 3 hrs. wires are all hidden and carpet tucks away perfectly in everything. You have to have them spaced off the metal cuz the speakers were too deep. I used these spacers from lowes to prop it off the metal and give it proper clearance. They are basically spacers with threads in them. This allowed me to drill holes and mount the spacers then mount the speakers to them. tighten it to the spacers with bolts.hardest part was being at the awkward angles. no rattling and sounds awesome.
