Galaxy tab 2 install-Need help with getting audio from tab to speakers/amp

Trying to do a galaxy tab 2 install on my Dodge Magnum.

Have my basics for the galaxy tab install.
Tablet
Dash Trim/Bezel
Double din kit(really cheap)
Volume Controller(Really cheap)

But need help with audio from tablet to speaker/amp. Ive been doing as much research as possible and it looks like im going to need a mini amp and a noise filter. These go from anywhere between $20 and couple hundred bucks. Looking to get a decent sound, but not trying to spend alot of money. Would it be easier to hook up a single din unit, and plug tablet through radio? I can find a 4x50 watt radio for cheap. Any help would be appreciated.



Right now im running a old pioneer Double din DVD player(5incher). Had someone else do the initial install to my car. I have a single 15 in a ported box with a amp but its nothing special.

All my research is pointing me to a Clarion EQS746.

It comes down to this or a cheaper head unit.
