Critique my upcoming setup.

[IsLNdbOi]

Yes, I know I have a similar thread on this page from over a year ago, but I have a new Yaris and need a new setup.

I'm suprised at how "good" the stock speakers on this 5-door '09LB sounds so not sure if I even need to replace the ones in the rear. I want to replace the ones up front because I want tweeters.

Here's what I'm planning on picking up so far:

HU: Pioneer FH-P8000BT
Amp.: Alpine PDX-5
Front Speakers: Alpine SPS-600C
Sub.: Pioneer 10" shallow mount sub. w/ custom sub box that fits in / on-top spare tire

Maybe Rear Speakers: Pioneer TS-A1628R




I'd like to keep prices around what I have right now for each component. If you've got suggestions, please don't hesitate to add them here.

Oh and I contacted this guy on eBay:

He's going to try making a spare tire sub box for me.

Thanks!
