Factory system is not bose, just regular.

The factory rear speakers sounded GREAT but were blown. Got new aftermarket ones that had over 900 great reviews and they sound like crap.



The old ones, which i think were a 2 way 6x9, (new are 3 way) made it sound like you had a subwoofer. Old speakers are 2 ohm, and new are 4 ohm. Any ideas????

 

You stated what the problem is. You matched the physical size of the speakers but you did not match the electrical characteristics of the speakers. Getting the ohms to match is very important in the world of speakers, in fact, it is more than very important.

You will never get any brand of speakers to work correctly if you do not match the ohm value needed by the head unit. The 2 ohm value is not the aftermarket standard, it is proprietary to car stereos. You can try to find 2 ohm speakers, but unless you go through the dealer, you probably won't.

Maybe and it's a big maybe, you can find an impedance matching device called and L-pad. I don't know how available they are. Try crutchfield.com, maybe they can tell you. Or maybe pac-audio.com

Maybe you can find a car in the junkyard with the 2 ohm speakers. Otherwise it is replace the head unit and the front speakers as well.
