recently departed from the bb install dept - i can tell you that the free install only applies to radios priced over 99.00, labor is free.... but, you must pay for shop material fees.. $5.00 and of course parts, dash kit 18.49, wire harness 18.49, antenna adapter , 12.49 .ect... they do not make any money on the free deck installs but.... parts whey clean up on (cost on dash kits & wire harnewss is 3.50) ... there amp wire kits in my opion are very expensive... and they will typically sell you the $99.00 only
speaker install $37.99 a pair
2 channel amp $64.99
4 channel amp $74.99
get this - screw subs in a box $12.00 each
sat radio hard wire - $59.00
deck install $ 49.00

remeber you also have to pay the $5.00 shop material fee each time you have something done
