I gave up trying to adjust my HU and amp. I have sound coming from my components in the doors but all I'm hearing are the highs coming from the tweets and no mid bass at all. I have an old school Alpine 7864 and the Soundstream Van Gogh. There are a lot of adjustments and not sure where to begin. I can adjust many levels on the HU and no matter what I tried, I could not get any mid bass. Any tips on how to adjust the system?

 

What speakers do you have? Components? Only use one crossover, either deck or amp. On my Alpine, i disabled the crossovers and Im using the one off the amps.
