What brand of speakers should i get for my car?

I am getting a new stereo and speakers for my 91 Mazda miata. My car guy told me to go to crutchfield.com and find some i like and he will put them in. So I looked a bit and found these http://www.crutchfield.com/p_777P65C/Sound-Ordnance-P-65C.html?tp=105 has anyone had them or know if they are nice or not? I do not want to spend to much money on these and to much is around 150 or above. The stock speakers are still in there and they are lame. If you have suggestions for stereos that would be great as well. The one that caught my eye was this one. http://www.crutchfield.com/p_070XHD6420/Dual-XHD6420.html?tp=5684&tab=detailed_info#tabs
