no sound

Ok I rewired my truck for new speakers and when I plugged my head unit back in a got power and all functions on the unit work cd even spins and everything but I get no sound out of the speakers im positive everything is wired up right does anyone have any idea what's wrong and what I can do about it

make sure none of the speakers are grounded out. Like i put panel speakers in my b2200 and found out they was grounding to the metal and causing no sound. So i had to take them out.

Lol man out of all the stuff I checked that was the one thing I didn't check

like if you installed panel speakers in your side panels other wise known as MIDs. If its like mine, my sides are metal.
thats problly the problem,even if you cover the back with black tape yea it well work for awhile but then it wont. Its just aggravating to me.

the speaker output on the deck could have gone out make sure the harness is plugged in all the way
