Hello and welcome to the forum.

Those look like some fine speakers. I'm sure someone here who has changed out their speakers will chime in soon with an opinion. I know that since there is not much room clearance can be a problem, particularly with the window glass.

If your going to keep the stock radio and not add a amplifier you want speakers designed to do that. JBL has some great speakers that give max power from a low power stock radio. These speakers are great if you have power though.

I will be putting in a new LCD navigation unit eventually.
The Alpine speakers will have more than enough power to support.
This is the speaker pack I am looking at putting into my car.

Yes the speakers will be able to handle a lot of power, but without the proper power into the speakers their performance won't be as good as a speaker designed to work off headunit power.

The stock mirage headunit puts out 140w max x4= 35w max each channel. Normally rms (continuous power) is around 1/3 of max, so probably around 13w rms per channel.

With a aftermarket they are normally 200w max x4= 50w max per channel. This will give about 15-18w rms

Those speakers your showing are probably 40-60w rms which a headunit will only power them 25-40% of their potential.

Having a JBL speaker that is designed for headunits will give you closer to 50% potential with their lower ohm resistance.

Infinity also are high powered speakers but they also work well with head units, you will loose some base with the infinities but they are very good.

I ran JBL components against these and they were almost as good without the amp, very good headunit speakers.

Some prefer infinity and I agree they are also an excellent choice
