I know this has been gone over, but equipment gets upgraded all the time.
So, 03 Durango with Infinity sound system. Need to replace all 4 door speakers.
Infinity Reference series seem to be popular. Which current Infinity's have been making everybody happy? Or let me hear what other 2 ohm speakers sound good.

 

I replaced all 4 speakers with Infinity Reference 6032cf which are 2ohm speakers and couldn't be happier. If you are going to keep the stock Infinity system you need to get 2ohm, I initially tried some 4ohm speakers and the sound was terrible.
