The other day I noticed that my rear doors sound quality was not that good. I wasn't sure if thats how they all sound or just mine. Any thoughts ? If I have to get new speakers that's fine, I just want to know if anyone else had or is having this issue

 

They are bandwidth limited - I would not expect much from them on the factory system. Most "audio peeps" will forego rear door speakers and focus on the front stage (my rear doors are still connected - but faded off on the aftermarket system) - but the factory system won't get you far w/o a bunch of work and add-ons (DSP and amps). Replacing factory speakers while retaining the factory system and DSP (and un-modifiable DSP tune) is a crap shoot at best...
