Was the old radio the Infinity version?

 

if you got no sound from the replacement radio, double check the fader & balance settings. Its output might be damaged or you have bad spkr connections....or 4 bad spkrs. in addition to the 1st radio that died.

If your truck was originally equipped w/Mopar radio, new 2-wire spkrs are PNP.

If originally equipped w/Infinity radio, its 4-wire speakers have external amps attached; therefore, new 2-wire spkrs are not PNP. An amp & crossover are required unless you replace the radio with one having an internal amp, say...27 or 52 watts x4 channels (your recent replacement?)

Recently, there was a similar thread from another forum member here with Infinity, though the OP hasn't provided a conclusion>>:

Another member, Spillage (a "Record Breaker"), contributed the following to that thread:
This post covers the Infinity speaker wiring in my 98, and how I rewired aftermarket speakers.
Maybe that will help.
