Hmmm...what to get.

Well, I'm confused once again.
Now when even if I say I have decided on a sound upgrade, doesn't mean it's final.
Thus why I jump from performance to sound I guess.
I'm THINKING, just thinking about doing an upgrade in the future on the sound aspect of my car.

My friend works for bestbuy and gets deals. So, I'm thinking of what to get.
He says he can hook me up with whatever is in the store for cost price (what the item cost best buy)

They carry Sony Explodes, Rockford Fosgates, MTX Punch Eichei 2's (I think) and some other subs can't remeber.
Now I can either get that, or buy a PS2 with an LCD screen and have that in my car (both around same price in the end)
What do you people think I should get.
I only have a Kenwood deck in my car so far.
