2000 Ford Focus Car Stereo

I'm buying a double din stereo for my 2000 Ford Focus, and before I order it I want to consult some others about the parts that I will need to do the install of it. This is what I have so far:

This is the deck i'm getting:

This is the housing for the sides to mount it in the dash:

Wire Harness:

Antenna Adapter:

Then I have the key already to remove the current stereo. So my question is, what else do I need? What advice do you have? Any and all help is appreciated.

Can a High-End Mechanic fix normal cars, for example, a Ford Focus?

I'm inspired by cars and I want to know if a High-End Mechanic can fix a normal car on the street like a Ford Focus. I promised my grandpa to go to college and learn to be a mechanic ( by the way he told me he would give me 1 acre of land to build my own shop, if I became a mechanic ) and i want to be a mechanic that can fix any type cars. For example, I want to know how to fix a Ford Focus, Toyota Camry, and Kia Optima all the way to Lamborghini Huracan, Ferrari California, etc etc. If a High-End Mechanic can't do all that, then my question is, what type of mechanic can do that?

Loud roaring type noise accelerating between 40 and 50mph?

Ford Focus recently serviced but after a week began making a roaring type of loud engine (?) noise accelerating between around 45-50mph. Plus some window vibration. After 55 and cruising at 70 no more noise. Yet it returns when the speed goes back down to 50 and then disappears in the low gears and low speeds.

Exhaust? Bearings? Seals? Wheels?

What's that thing called when young boy racers put on there car to make it sound loud?

Is it the exaughst? And where can I put this on my car (ford focus 04 three door 1.6) I want that cool loud sound on mine, so where do they get this these young kids? And how do I go to a garage and explain this to them? And will I look stupid asking the question to the garage worker?

Bought a used car that was in an accident. Terrible idea?

I mean for what its worth I have already purchased the vehicle… So… No going back now. A 2013 kia optima w. Low mileage (24k) and in brand new condition, full manufacturers warranty still w. The car. Anyway, the autocheck revealed the accident and the dealer was extremely honest about it (he mentioned it when i asked if it had any dirt on it… Which is why I bought the report). There's no trace of it having been repaired… It looks brand new inside & out. I didn't really think twice about buying it… Perhaps bc I've been in some very major accidents in all my cars and drove them around long after lol. (one time i had a brand new ford focus and a tow truck literally ROLLED OVER IT, the airbags were faulty and only deployed when the mechanics drove it around 11 weeks after they finished fixing it - that hunk of metal would have been totaled for sure if it weren't brand new lol) Anyway, this car was in a decent accident - passenger side collision where the airbags deployed. But no frame damage… Clean title. Should I be very concerned? I mentioned it to a few friends and googled it and everyone seems to think it is the worst idea ever. I don't know. Was i foolish? I bought the car outright and have no plans to resell… I don't really know what to look out for since I'm stuck with it now I guess.

This was really long winded! Sorry. I'd love to hear any concerns or experiences w. Buying a used car w. Accident history.

Why does my Ford focus take a while to get started?

Details: 2007 Ford Focus SES 4dr hatchback ( 2.3 liter I believe), mileage 107, 588.

I've been having some issues when trying to start it up some days. It takes a few times of turning it over before it starts. It now progressively seems to be taking a bit longer to finally turn over. I'm trying to figure it out and see if it's something I could fix personally or just bring in to get it done by a professional. Luckily a buddy of mine works at a pretty respectable auto shop.

I have a like new battery in my car as well.

Any thoughts?

2009 Ford Focus power steering problem?

I have a 2009 ford focus and my power steering is leaking for the reservoir cap. I will fill it up to the max level and go for a drive and when i shut the car off a bunch of fluid comes out from the cap. The fluid is a dark brownish color so i don't know if i just have to do a flush or if the power steering pump is going bad

Is it illegal to use coloured tape on Car?

Is it illegal to use coloured tape on your fog lights in Ontario? I drive a Ford focus and take transparent blue tape and cover my fog lights rather than my headlights. I understand I'm more likely to be pulled over for drawing attention to myself but don't want to deal with a ticket. Would tape on your fog lights be an "illegal mod?" Thanks in advance!
