I wanna replace all four speakers, I know they are 61/2 and 2inches deep.

Any recommendations? I'm willing to spend up to $200 for 4.

Questions:
-Whats a good brand?
-More channels = better? (i.e 3 way is better than 2 way.)

As far as amp goes I want to spend the least while getting the most out of it.
What do I require? Looking not to spend so much on this. >_<

Im looking for a small 10in one subwoofer in the back that wouldn't take up space. Any recommendations?

 

I like my Polks, but they are heavy on highs/mids. You would need to run a sub. Maybe this will help: http://m.fitfreaks.net/forums/showthread.php?p=1036630

Rear speakers;

Both in your budget.

As for an amp, you will have to go above your quoted budget, trying to buy 4 speakers that don't suck and an amp to power them with all the wiring and accessories needed isn't feasible. Unless you are gonna hit a flea market and buy no name brand speakers which won't sound any better than your factory ones.

Decent 5 channel amp to run everything, all 4 speakers and a sub.

Now the only thing about adding this amp is that your factory head unit does NOT have RCA outputs, which means you either have to use a line output converter, bad option IMO. Or you need to replace the factory head unit, this is the better option IMO.

The total at this point is $431.75, with free shipping on all of this.

As for a head unit, you need to decide keep factory or not. If you decide not to then I would look at do you want a double din or a single din unit. You can pick up a nice double din for around $350 for the mildly featured units and upwards of $900 for a top of the line model. Here are two examples;

Pioneer AVH-P2400BT DVD receiver at Crutchfield.com

Pioneer AVH-P8400BH DVD receiver at Crutchfield.com

By ordering your head unit from crutchfield you get all the necessary installation accessories for free, kit/harness/antenna adapter and instructions.

This all may be a bit much so maybe if you are wanting to keep it low budget you might wanna check out a bestbuy/walmart they usually have pioneer speakers pretty cheap. It's all about how good you want it to sound and how much you are wanting to spend. Yes you can get a lot for little but you cannot get good sound for nothing.

 

Great post Fit4Spl

 

For amps, check out the Rockford Fosgate PBR300 series. I use the 1 channel for my sub and it's really nice. Fits perfectly mounted to the cross bar under the passenger seat.
