SHTF said:How do the 4ohm sound?
I'm looking at the JBL's since they are 2ohm, will keep you posted on the outcome
I ordered these on ebay since they are $75 and don't have the tweeter in the center for the fronts

The Polk are 2.7!ohm. I'm running an Arc Audio amp so I can't comment on them with a factory amp.
They are 2 3/4 inch depth and fit using the modified stock basket.
