undefined Hello, i was just finishing my installation in my 03 accord and when i finally wrap thigns up w\ the amp setup and go back to reconnect the negative terminal and test out everything, the HU turns on, but i get no sound

. ive checked all connections and i know the speakers and amps work (tested them seperately). i even get no sound from the stock tweeters up in the dash that i have not tampered with at all. any help would be greatly appreciated as im really frusturated right now.
thanks
