So I put in new speakers today in the dash and no sound. So I checked the wires to at least see if they were connect to the head unit and yes they are. Is there a voltage reading or something that I can check to see if the front channel is bad?

Make sure the fader is set right, if you are checking for sound from FM make sure the Ant. is plugged in too or you will get no sound.
Did your old speakers put out any sound?

Rear speakers work but sound like crap and I have a set for those as well. Front did not work but were heavily damaged so I assumed that was the issue. Fader is set properly.

You can plug in the front speakers to the back channel, and visa versa to test.

That was my next step, but I wonder if there was some technical stuff I could check.

The front channel is toast front speakers worked in back. They are 4 ohm so sound is really low. Looks like I need to do some shopping I just didn't want to do that yet.

Sounds like the whole radio is toast. 4 ohm shouldn't make the sound lower as amplifiers make more power the lower the ohm load they are presented with. For instance a radio making 10 watts at 8 ohms should make closer to 20 watts at 4 ohms. The drawback is that the lower the ohm the closer you come to a dead short and the more likely you are to blow the amp. However, the stock radio should be okay with 4 ohm speakers, but I wouldn't go lower. What this all means is that the radio just isn't "putting out" as 4 ohm speakers should be just as loud or louder than 8 ohm (assuming your not trying to push a 18" sub off your stock headunits amp...
