altima 2ohm speakers?

while wiring my amp a midnight i noticed the rear speakers are labeled 2ohm, i am wondering if the front speakers are also 2 ohm and what effect this will have on my new head unit that i have not installed yet. it is a jvc kameleon, also will i need to replace all stock speakers? if so whats reccomended?

Lots of car companies are running 2 ohm speakers these days, especially in "premium" audio systems.  Your JVC head unit will not like this, as it is rated at 4 ohms.  (the actual rating on the KD X111 "El Kameleon" deck is 19 watts RMS per channel X4 into 4-ohms.)

I highly recomend you replace the factory speakers.  HERE is a good web site to help you remove and replace them.  Watch out, if you have the "Active Sound System" there are factory amps you will also have to remove and/or bypass.

i do believe the rear speakers have "NDSS" written on them is that the active speaker system? if so does that mean the front speakers are 2 ohm and if i bypass the amp all that will be needed to be replaced is the rear speakers?

where would the amp be located?
