2013 chevy malibu, rear speaker wiring

I want ot put in rear deck speakers on my new 2013 malibu. others in this forum talk about just patching into the rear door speakers. will that give me the same quality and is that probably the best way to go about it? my car is new so i really dont want to be digging under the dash for all the wiring b.s.involved. should i just patch into the rear door speakers? thanks a lot.

Don't patch, disconnect the rear door speakers other wise you will get impedance problems affecting the amp and distortion.

thanks. ill do exactly what you suggest.
