its all in the install. for $120 you are getting fresh 16 guage wire ran from the deck, to the xover which stay in the passenger compartment, thru the grommets to the speakers, mdf speaker plates, and some basic FG or colormatched tweeter mounts.
any other shop in san antonio including audio concepts, audio express, and quite a few other who i also know personally do not do this. they use stock wiring, mount the speaker to the metal door, mount the xovers in the doors, and run a hole saw in a door to mount a tweeter.
quality over quantity...if you dont understand a quality install, GTFO
