I got to say, I'm in complete disbelief that a 1997 nissan product is still on the road today. They usually fall apart as soon as the warranty expires around here.

That head unit probably is 2v. You should look at getting a better one with at least two sets of 4v preouts.

The speaker issue shouldn't be too hard to figure out.

How can I test the front speakers since I am using a harness and factory harness is still there? Lady at audio store just said if I switch the 2 rca around and front still doesn’t work then it’s probably my speakers not the stereo?

With a multimeter.
