I recently had a dead battery in my 2000 civic ex from the cold weather. I had the battery replaced today, and now my subs and amp dont seem to be working. Its an audiobahn amp. When i turn the head unit on the amp turns on, but the digital voltage meter on the amp doesnt come on. THe amp has power and everyhting is connected. Any idea what this could be. Its a sony mp70 cd/mp3 player. if anyone has any ideas id really appreciate it, ive already tried reseting the deck.
