you have to be more specific. what products are you getting? subs? amps? cd player?
figure this for a cd player (canadian dollars btw): cd player $200, wiring harness (so you can just unplug the cd player and put the stock deck back in/when you sell the car) around $16, and around $20 for a bezel around the cd player (also includes a pocket to go below the cd player, to hold CDs, etc)
for the install alone for a CD player, i would never pay more than $50, becuase all they are doing is taking off one panel (around the cd player), hooking up the harness (shouldnt take more than 15 min for a professional installer) and installing the bezel/pocket (5 min max) and then putting it all back together. should be a 30 minute job, or not much more.
if they are putting in door speakers, or subs in the back, then it starts to get expensive. they have to take the door panels off, run wire to the hatch for the amps, put in grommets at the firewall, etc. so if that $255 is for all of that, with $85 for the harness, RCA cables, and power wire for the amp, i would say its a decent deal.
