Amps, which way to go?

First off, this is my first post, so I hope I'm not treading on ground already covered, but my attempts will be to add an amp to a Pioneer MP3 Premier 50x4 head unit, and possibly a couple of 8" subs.    This will be going into a mid '90's Ford Supercab pickup if that helps at all?

I've been watching Ebay for amps, and I'm thinking I will need a 4 channel amp, as I believe I would prefer to have additional power to all 4 speakers (which have been replaced just last week to the tune of $400.00+).    I'm thinking if they don't make them, a custom box of some sort will need to be made to put two 8" subs in to, to fit under the rear seat?  

My music tastes are more POP, some CW, a bit of dance now and again, and even the odd Mozart, so clearity is an issue as well.   As for AMP size (wattage) since I've never had an amp before, I'm not quite sure how much is not enough...and what wattage is too much?    I'm not looking at blowing my ears out, but one that can "rock" the music when needed.

I believe I'd rather spend a few extra dollars if that's what it takes, but I certainly don't want to break the bank either, so perhaps some advice on the higher end for an Amp...and what kind of money I might be looking at, and some makes/models of decent subs would be beneficial as well.

Thanks in advance, as it's much appreciated!

Ravendarat has made a good point about the second amp. I would not be looking to e-bay for an amp either, it is too easy to get burned with no recourse at all. This just happened to another customer of mine on Friday. $180.00 repair bill for a e-bay amp. Buy local, buy from an authorized dealer, always. Another good basic 4 channel is the Eclipse es3422, Concept CA604, Lightning Audio B2.300.4. All these amps should be in your price range. A good 5 channel amp is the Eclipse PA5422, or Crossfire VR705D should you want to power all speakers from the amp. These amps will easily deliver all the power you need to run all 4 speakers and 2 8" subs. I used a 5 channel for years to run the same speaker set up without fail.

Thanks alot.   Never thought about a 5 channel amp!

Most local vendors I've seen, want about $400. for a 400 watt amp, plus installation.   That is why I was thinking more of Ebay, thinking that perhaps I could find more of a top quality (perhaps even used) Phoenix Gold (or similar) for about half that cost perhaps?    I didn't realize that repairs on amps was so expensive.

Any, and all information such as this is quite valuable to me, in that this is a whole new area for me, of which I don't know alot about.   Are the other things I should pick up, such as wiring, fuses, fuse boxes or any other incidentals I may need, or just leave that up to whom I get to install it?    I did stop at one vendor, who also specializes in making custom boxes for subs, so perhaps I should just leave it up to them?

Thanks...great info!
