About a year ago I installed a bunch of the Kicker line in my F150 crewcab. I bought a Kicker IQ series 1000.1 amp and their 6.5" QS series components. When I installed the fronts (not running any rears), I used the foam rings and put down KnoKnoise sound deadener and covered the major holes with sheet metal and more deadener. Initially I was using the passive crossovers that come with the speakers, and last week I finally got around to bypassing these and running active with the IQ series amp.
My problem is that I have to set the crossover to the point that I'm cutting out most of the lower mid range bass. I set all the gains with a DD-1 so it's not clipping, it's just like the speakers can't play very loud with any sort of lower frequency. I'm not trying to get all my bass from the fronts, as I'm running a sundown zv5 with 2500watts, BUT I would like to be able to turn down the sub at times and have a complete sound from just the front stage. If I turn down the sub now, the sound is not "tinny" but it just doesn't sound complete. I can definitely tell the bass is missing from the sound. What's sad is I can get in a new car and hear a little 6.5 "bump" better than what my truck does.
What am I doing wrong here? I feel like the door is fairly sealed but these things just don't sound right. Any help is appreciated. Just want to have a really clear and loud stereo.
