The reason they are probibally 2ohm is that they are hooked in parrallel with the tweeter,my quarts are 4 ohm but run through a crossover and they sound great.a factory system usually will not use a passive x over for there seperates just a capicator for the tweeter and run the woofer at full range.
This is a cost saving method for them.I will post pictures soon,I also added
a subwoofer volume control knob in one of the knockout plugs in front of my console it works perfect and looks stock.I can dial in the amount of bass I want.I also noticed that the rear door speakers have a 200hz bass cut off
at the factory amp,so if you replace them dont expect too much bass from the rear door speakers,just mids and highs.I had to make a tweeter bracket
for the front doors,just unbolt the existing tweeter and trace around it to make a template,I used 1/8" steel and painted it black,for the 6X9" front doors I purchased adaptor brackets from crutchfield and they work great.I used 5 1/4" speakers.,you would not believe how much better it sounds
just adding a sub with volume control.Even with the factory speakers,you probibally blew the front 6X9" because you turned the bass all the way up
on the raido to compensate for the week factory subwoofer.If you want to try this I can tell you exaxtly what to do and what to buy.I have the JBL six
disc in dash changer with rear seat wireless system.
