I recently got new 500w speakers for the rear of my car. I also got a 400W amp, and replaced my old deck to a Sony Xplod. I will list everything below. My friends helped me set everything up, everything seems to work but there is literally no bass coming from my back speakers. The front seem to be normal as they were before, but it's hard to tell since they are still OEM. The new speakers i got are connected to a crossover, which is connected to the amp. Is the crossover ruining the bass? I also don't have the tweeters installed yet that came with the speakers, do they need to be connected in the crossover at the same time?
I messed with the equalizer on the deck and I can't get any more bass coming from the speakers. Maybe I don't have the positive and negative going from the crossover to the amp correct? Any help will be greatly appreciated.
