I'm upgrading the system in my taurus and want to replace the crappy stock speakers I currently have. I'll be using the stock headunit, but I'm buying a mach amp that'll bump the output from 13 watts to 80 watts. I'm not going to go with a sub. Both the front and the back speakers are 5x7/6x8. I'd like to keep my speaker budget under $200, preferably under $150. Any brands/models to avoid? I'm open to any and all recommendations.

So far I've found these speakers
