Entertainment systems / Audio?

Hi, I just signed up, and I will do my best not to step on rule #2 - Advertising
Way before being a truck driver, I worked for a major audio company as a prototype specialist/ special projects when I wasn't doing that, I did assembly or testing of speakers. We did car home and pro audio speaker design. We also did factory upgraded audio systems for specific cars that were factory integrated to keep a car from getting all those extra subs amps and aftermarket stereo systems etc

When I got into trucking, I realized how much money truckers spend on their rigs, and when I got into various trucks I realized one thing missing is entertainment. I personally have a 2015 Cascadia Evolution. I have had a 2012 Cascadia, and a 2007 Volvo also. Atleast between the Cascadia's I noticed everything stays the same, same speaker sizes, stereo type.
The Audio sucks! Lacking bass and imaging. When I close down for the night I imagine a 27"-32" mounted in the storage upfront and watching TV at night, or some movies. Or to just upgrade the audio so when I drive I can enjoy my music.
With my truck I swapped some speakers around and did in cab testing of sub woofers, and I was amazed what you can do with out touching the wiring - doing plug and play systems that would never void warranties, and if your a company driver, you wouldn't need to cut and splice or do anything custom, and when your done with that truck, weather quiting or switching trucks etc, you can just unplug the new speakers and pop in the old ones.
I'am looking at a Home theater kit that should be able to ran off the cigarette lighter, one for the amplifier system towards the back, and one for the TV, or a 2000+ watt inverter would be best for higher power set ups.
If I do this I would want different levels, and well, at first just for the Cascadia's, 1) because they are so popular, and 2) until I get another very popular truck to do R&D on, that's all i have to go on

So, Iam looking at 6 levels as I said, and want to see what your ideas on what would be most popular- what do YOU WANT?
This is what I came up with so far- And by the way, my friend has all this in his ship, so if I ever do feel it is possible to do this, its all on hand.

Level
1) Replace stock speakers with plug n play aftermarket speakers, a high end brand that is very respectable
2) Replacement of speakers and upgrading the stereo to an aftermarket stereo like a Kenwood/ Pioneer with Blue tooth, HD Radio, Satellite, RCA connection out puts and inputs, SD memory card and USB input.
3) Above to with a 300-500 watt subwoofer from 8" - 12" ( Custom available)
4) 1+2 and a TV wall mount with high quality side speakers, and separate subwoofer and DVD
5) In dash Double DIN - DVD player with navigation/TV Screen + 4 speakers + Wall TV mount + Subwoofer
6) Just TV wall mount + subwoofer - separate from stereo system, no key needed to turn on

I just came back from being on the road for 65 days, and I tell you, I wish I had at least a TV and dvd player (I left my laptop at home)

So, again, Iam not advertising, this is a poll, I want to see what you guys would want, if had the option

 

Well, I do not know how to fix the poll thing, but please mark what you feel would be nice to have
Thanks!

 

Those are nice trucks, Iam envious of them lol.
As far as the muddiness, let me explain how/why that is.
You most likely have 5" and 6x9" speakers in your truck, and having such a huge cabin, your speakers and ears conflict as far as what is heard and being played. Because of the such large room of a big rig, your lower frequencies lose all power- In a Ford Escort, I bet it would sound so much better due to the smaller cabin area. I know it would, physics tell me it would.
So mainly what happens you hear a song its got drums vocals, bass guitar, and your stuck changing the bass and treble settings to compensate for overall volume, you notice you cant turn it up as loud anymore because the bass was turned up- gets distorted, and muddy. The cones of those 5" and 6x9 speakers are moving a lot more now. Here is the main problem since the cones are moving a lot more, those cones also reproduce about 75% of the sound you hear (if they are coaxial - if one way drivers your screwed) the cone can not accurately produce those other sounds over the bass- the added cone movement.
So in this case, just a simple 8" added subwoofer would fix everything. You can cut way back on the bass control, maybe start to roll it back down to negative ( bass/treble middle points are usually set at 0, all the way up it may be +12, all the way down may be -12 so with bass/treble centered that is usually the flat point)
So yes you can be benefited with a good 4 channel amp to where you can crank your speakers up with less distortion - but as a company driver, that wont happen, but by replacing the factory speakers with aftermarket more efficient ones and adding a subwoofer, you would be golded.
As for the subwoofer, I have been thinking of subs that can be plugged in directly to a cigarette lighter and an amp up to 150 watts for that. Taking the low end stress from those door speakers will be night and day difference
