It shoudln't take nearly 50 hours to install comps, deaden the doors, make / carpet a box, run wires, and... well, that's it.It took me 43 hours running wire/rca, doing the big 3, installing amps / fabricating amp stands, designing / building a 3.5 cubed ported box, installing said box, tuning amps.
And that's by myself. And I'm no professional and I had nothing but wire strippers, a flats head and phillips head screwdriver, table saw + clamp & glue, and I borrowed my Dad's air saw to cut the holes...
I expect a lot quicker install from a shop. But, odds are, they're gunna half *** the install even though they're charging a lot. Because, most shops have this mentality that once the car is out of their shop, it's not their worry. Most shops (notice most, not all) have little to no integrity. I've seen a few stories where the shop apologized, and reimbursed the person and re-did the install. But there's a plethora of stories where the shop told the person to fuck off, and it wasn't their problem.
And that's why local shops are going under. Over-pricing for shoddy work.
Yes. It's not. But why would it take 3 days to do a normal install by professional installers? They should be able to run the wires, install comps and deaden the car with in a day (8 hours).
