Just picked up a 94 Rodeo a few days ago. It had the stock radio in it and it worked fine along with all the speakers. however i do not own any cassette tapes so i got a new pioneer headunit. whent to go hardwire it in and got it all hooked up and installed. headunit turns on no problem and functions fine, however no sound at all from the speakers! i re-checked my wiring and even took a AA battery and touched it to a set of the wires that were from a speaker on the stock harness and the speaker popped like it should. Sooooo why wont i get any sound when i have the head unit on???
