Well with a 12 inch sub, and 5.25 mids, i have a distinct lack of midbass.
I have 2 8 inch woofers (not subs) that i thought would fill it in nicely. The only question is where i could possibly mount them. Of course I want them up front somewhere.... I was thinking about kickpanels but I'm not sure they would fit.
Do you think if i mounted them next to the rear seats in the huge panels that it would sound wierd having the mid bass behind me?
Assume I have them bandpass crossovered and amplified nicely.
I was thinkin 70Hz to around 250Hz.
Any opinions?

You might be able to get by with the 8" in the doors but you will have to do some fabricating and you will also have to watch your depth.. i have 6.5 in my doors right now (3" depth) and the window barely squeaks by. If you do fabricate something in the kickpanels it will take away your already limited footspace not to mention your left footrest when taking those sharp corners!

Custom make lower door panels out of fiberglass, it's a great project to do, you learn a lot. The speakers are not going to fit without major modification. In the kick panels it is 99.9% impossible! The crossovering sounds like a good a good start, but remeber tune until you get your favorite sound.

You could put them in the doors and that would be a challange. but then you'd have to find a place for your 5.25's. I wanted to make kicks but decided that that'd be very hard to keep my foot space and make them sound ok. You could possibly try and mount them in the center console under the radio. Kinda like this with the purple being the drivers:

well i would be willing to sacrifice some foot space for midbass, but this is not making me optomistic.
I've never done fiberglass and my geuss is that i would make my doors look like crap. that would suck.
i dunno what to do.
thanks for the help

know you want them in the front, but worse comes to worse you can probably get them to fit in the back, where the rear speakers are.
ears are more directional to higher frequencies anyways

yeah im pretty sure i could fit them behind the front seats near the rear speakers.
I think that even mid bass frequencies are too directional to have behind you in the soundstage.
I went out today and dug my car out of a pile of snow and looked at the situation and it appears that 8's in the kick would require quite a loss of space -- too much.
I think maybe i'll buy some relatively low depth 6.5's and try it with them.
and then still put the 8's in the back. :)
that'll be cool.
now i just have to figure out how to amplify everything with the 6 channels i'll have.
it'll work. it has to.

With a single 12" sub you should not have a lack of midbass with 5 1/4" mids. Are you sure you haven't overlooked the phasing of the mids? If the two are out of phase then mid bass will frequencies will get cancelled out.

My 5.25's are infinitys that the manufacturer only spec'd as playing down to 80 something hz, which is probably where they're down about 3db from anything close to flat. From what i can tell they dont really like to play anything below 150 anyway.
I cant stand anything over 70-75 hz in my sub because its aimed up at the rear glass and sounds horrible, plus i lose power to the real low notes anyway.
this leaves me with a small hole in my frquency range.
I'll admit its not a huge problem.
btw I'm sure the 5.25's arent out of phase.
