The amount of time it took me to install was considerably bumped as I ended up getting into a bunch of "As long as", installing a secondary fuse panel to the right hand side battery for the radio, amp, sub, and A/C so that I wasn't tapping off the main panel with ugly inline fuses. Installing more sound deadening and then upgrading the stereo with better speakers and doors, fixing the rust I found on the floor pan.

Also as I have a '71 I had to mount the condenser in the back. I'd guess it could be done in a solid weekend at home with tools, so I'd say 8 hours for most home mechanics. An experienced mechanic who's done one before could likely do it in 4-5 in a later car I'd say no problem.

For me it took me more like 15 hours with everything else I was doing.
