Can I charge a 12v battery from my cars 12v plug?

I'm building a cooler stereo (cooler that has a car stereo and speakers in it) which is powered by a deep cycle battery.

The thing will spend most of it's time in the back of my car (when not in use) and there's a ciggarrette lighter socket in the back and I was wondering if I had a male to make plug, could I charge the battery in the cooler from it? The battery is actually bigger in size than the battery in my vehicle. (Ford edge)

Ford KA speaker not working?

My drivers side speaker doesn't seem to be working on my 97 KA, I've managed to get the door card off and have gotten to the actual speaker but that's as far as my knowledge takes me.
What should I be testing? I have a multimeter handy but I have no ides what the wires are and where they lead.

Any advice?

How early can i trade in my leased car for another lease?

About a year ago i got into a ford focus 3 year lease. I'm unhappy with the car and the problems it has, etc. I'm really interested in getting a f150 or edge or even explorer, something bigger with more room. I still have two years left but i've heard that its easy to drop that lease if i lease something else. Anyone have any ideas or opinions?

Why are my breaks squealing?

I have a 98 Mustang GT. Recently I had a blown caliper on the rear braking system, fixed it about 3 weeks ago now I have a squeal coming from (sounds like) the front. It happens when I lightly touch the brake pedal, if I depress it more aggressively it doesn't make noise. I have pulled it apart because I originally thought it was the squealers on the front pads making contact with the rotor, that's when I found out that the pads don't have squealers and they also have plenty left on them. My rotors don't look or feel warped and I even re-checked my rear brakes and everything seems normal. I've pretty well exhausted my knowledge at this point so any input is greatly appreciated (unless it's a joke about Fords) :)!

Thanks

For being 18yo, do I have any chance at becoming a salesman for this retailer?

I live in a small town, and there's a Ford car dealership about 10 minutes away. I just turned 18 and I need a job.

For all my life, as far back as I can remember, I have always been excellent at economics, especially marketing, and the born-ability to change the perception of the customer to (make) them believe that "… Our product is of the highest quality than any other you may find, and our company has a specialty in this criteria."

Anyway, back to the car retailer. I know that for every great market strategy, in my experiences and foremost opinion, gathering information is the best way to base and plan a good strategy. By that, I mean, I'm trying to create a plan of "This is why you need me!". I have driven by the past half year (I was in school) and I had noticed that the same cars were always in the parking lot every time I drove past. And once, I was interested in one of the cars they owned. And I had to wait seriously 5 minutes until a salesman came out to talk to me. And what a god awful sales pitch he gave to. Also, I have been looking, and I have never seen a single advertisement anywhere.

From what I hear, the owners are older people, own a dozen businesses, extremely rich, and has so much money & are so old, that they could care less what happens to there business. But that's only rumor.

I failed at school, mostly because I was extremely busy increasing my knowledge on learning the "physics" of Wall Street… Instead of learning how atoms worked.

I've been test driving a few cars and can't find anything I love?

I currently have a Ford Edge AWD and want something smaller. I love how high I'm sitting and prefer SUVs or hatchbacks to sedans, also need AWD. I driven the Buick Encore and it's comfortable and drives so smoothly BUT it's just not powerful enough for me. I want to keep my cost under 35k and still keep my goodies. I'm looking at the Nissan Juke (haven't driven yet) but am I too old? I'll be 33.

Can i trade in a leased vehicle early?

I have a 2013 Ford Edge and I'm about a year and a half into a 3 year lease. We're expecting our first child later this year and are trying to cut back on as much as possible. Currently we're paying $280/month for the Edge and would like to trade it in for a vehicle with a much lower monthly payment.

The vehicle is leased through Ford. Am I able to trade it in this early without penalties? Is there a different option that may be the smarter route?
