[QUOTE="breier, post: 7208201, member: 630281"] Alright, so i'm helping a friend install 2 sets of component speakers with passive crossovers, a 4 channel amp to power them, as well as a double din nav unit. Everything went in just fine, but when i went to turn it on, only the tweeters are playing sound (and it sounds like a full range rather than just the highs). So i took one of the stock speakers i just removed, attached some speaker wire to it, and it plays just fine coming out of the crossover, and even when i put it on the terminals of the new speaker i just hooked up. This led me to believe the new woofers were pooched. But then i took woofer lead out of the crossover and hooked it right to the speaker leads on the nav unit, and it played just fine. Then i also tried taking the woofer and putting it right to the amp (so bypassing the crossover) and it didnt play anything. The amp is set to flat (even tried putting it to hpf and lpf) and ive adjusted the gain and frequencies, i've also tried changed the settings on the nav unit too with no avail... please heeeeelp! I should also add, that when the volume is low or even at 0, you can hear a hum type of noise from the tweeters. [/QUOTE]
