Re: 6.5" midbass vs 8" midbass, options?
To get real midbass out of an 8" driver you may need to get a subwoofer. Then you start to want to build an enclosure in the door to control the response. Otherwise you can step down to the ~7" diameter and open up your options. A 3" or 4" midrange would work really well with that size of midbass, then that could be topped off with a 1" tweeter. I have options for these scenarios and I can make this work with a 4-channel amplifier and 2 passive crossovers or a 6-channel amplifier and a DSP. The latter option is much more expensive but it will allow for more control. I prefer to keep all the drivers close together on each side, but if you want to use factory tweeter locations that limits you.
