Audio Questions, Need help planning my audio set-up Options

[Keiri]

Everyone,

So I'm tired of the stock speakers in my GT; when I got the car they sounded fine but after driving it daily and hearing them in action they aren't as clear or crisp as the Pioneers I put in my previous car. I've now decided to replace the stocks with the following:

Front: Pioneer TS-D720C
Rear: Pioneer TS-D702P

My question is since the system will, at most, output 540W of power can I use the stock amp. or should I go ahead and replace/bypass it with an aftermarket amp? The amp I'm looking at getting is the Alpine PDX-5.

PS: Overall, this is the first step towards building my carPC if that makes any difference.

Any help or experience would be greatly appreciated.

Hm, I've owned a pair of A-series 4x6 Pioneers and the audio sounded pretty good, for a set of entry level speakers, so I figured the high-end D-series would be a good choice. What products do you all use?
