kenwood radio in my truck wont work

[Mr.Atc]

Im fixing up my 72 chevy luv right now and I got a nice kenwood radio for 10 bucks its model kdc132. I wired the radio all up and it lights up and turns on good but wont play sound out of the speakers. I rechecked my wiring the antenna is plugged in. I tried different speakers. Have the manual and wiring schematic so I know its hooked up right. Im thinking the radio is probably junk. What you guys think?

[trike savior]

yeah if you are confident in your wiring then the internal amp on the head unit is probably bad

I'd take it back to the store for a refund.

The only radio I used in my car is a Pioneer. JVC and Kenwood is junk.
I bought the cheapest (100$) Pioneer CD Player 10 years ago, put it in 3 different car and it still like new.
