Got some Clarion 6x9's for christmast

Those are them... I'm not a guru of audio equipment, but a friend of mine who has 2 15" subs in his car knows his stuff pretty well, and recommended these... said they sound almost like 10" subs... what do you guys think?

And do you think these: http://www.clarion.com/pwrsys/powersys09.htm would be a good compliment for the front speakers? Since the front ones crap out so easily, that even with the stock 6x9's I have to keep the sound to the back of the car mostly to keep the fronts from crapping out when it gets loud... someone told me it was the speakers themselves being underpowered... but it sounds like the enclosure that the speakers are in are vibrating or something... thoughts? suggestions?

I like bass, but I don't want to weigh down my car and take up half my trunk space for subs, so when I install these new 6x9's the next thing I'll replace is probably the headunit and the 6.5"s in the front doors... and that should probably be plenty for me as long as they're quality speakers

almost like 10's? i doubt that but you can get some good sound out of 6x9's.

honestly unless ur stock speakers are blown.......... i wouldnt spend money on other 6x9's......... our cars have awsome stock speakers to start with........

^ditto. i have been running 300 rms to my stocks for over a year and they are still pounding away.

Nah I heard these in the store, they're 3-phase and they sound MUCH cleaner and louder than the stock ones when cranked up, they probably wont be as loud in my car because of the stock headunit, but it'll be a definate improvement

you will be overdriving you factory headunit with those because GM uses 8ohm speakers in the rear and aftermarket speakers use 4 ohms

So what do you suggest I do?

And has anybody else had any problems doing this? I know I'm not the first to put in aftermarket 6x9s and keep the factory headunit
