my Hyundai car need to upgrade

[megancheung]

I want to upgrade my Hyundai car with car DVD player, but don't know much about it or where to start. I think I would want a new radio, new speakers, an amplifier, and subwoofers. Also what brands and models should I get? I want both good quality and loudness, but definitely more interested in the quality.
Here are what I found on the website:
Hyundai Sonata dvd player 1
Hyundai Sonata dvd player 2
How do I know which ones will fit in my car?
Sorry for the long question, and thanks in advance for any help/ insight you can give!

subs would sound better in a box in the trunk but im sure you wouldnt sacrifice much bass just goin with two 6 1/2" subs to replace the 6x9's in the back.kicker and jl audio makes 6 1/2 inch subs or you could have the hole upsized and use 8" subs. the 6 1/2 arent gonna fit perfectly into a 6x9 hole but ive done it b4 and you will b able to mount them in the back.

To me they are the same just in different colours.
You don't need to go back to hyundai to get a new radio. There are many in car entertainment (ICE) websites out there.
In the write up it says 2Din. This is the fitment size. Most cars have 1Din fitments, or can be made into 1Din with an aftermarket bezel which you could find on ebay or an ICE suppler.

This would mean you could fit any aftermarket radio on the available

Only your budget is what stops you from the total power of the stereo
