The closer to the listener a speaker is, the more dominate it will sound all other factors being equal. Proper alignment of speakers in the factory locations will improve stereo image and staging. If you use 4" seperates in custom made kicks you can avoid the e-brake extreme I described earlier. You can do it yourself with a little practice and patience. Door pods are even easier and would be a great place for 6.5" midbass drivers. If you let the pros do it you will pay around $350 for a set of kicks if QForms does not make a model for your vehicle. I made kicks for several friends for the cost of supplies and a case of Corona (proof of a Divine presence) because it is easy and fun.
