The MTX Thunder 1004 will give you 125 watts RMS per channel @ 4 ohms;  also so will the Precision Power PCX-4125.  They say the   Audiobahn A4801t will do 250 watts RMS per channel @ 4 ohms but I think that's a little inflated.  Still any of those amps will definitely give you more than enough power to push your speakers.

It'd probably be less expensive to just use two 2-channel amplifiers, especially considering you already have one of them, but it's gonna be harder to get everything to sound integrated and matched if you're using two separate amps than if you just had a single 4-channel amp.  That's not to say it's not possible to make it sound as good, just that it'd require a little more effort and planning ahead as far as the installation is concerned.

Actually I have already purchased the other 2 channel amp. I really wanted some tips for later use and those look pretty close to what I am looking for. Thanks for your reply.

The interesting thing though is the Bostons claim Nominal Impedance of 3 ohms. But the JBL are 4ohm. what kind of effect do you think that will have?

Are the JBL's for the rear and the Bostons for the fronts?  Or the other way around?

I do want perfect sound. But as how to get it. I am clueless. Besides stock systems this is my first system. I put it all in myself (which I am very happy about..) I am going to try to hit a competition so I can hear a good system and see what I can do to mine. This is great fun. And a lot of work., I appreciate all on this site for the advice and technical help. This hobby has shot up to Number 1 on my list. Thanks again.
