I just installed some pheonix gold 6" mids and tweets in the front doors of a 2000 ford taurus where the stock 6x8's were. Made my own baffles out of 1/4" mdf. I also installed some 5" mids and tweets in the rear doors. I used the 1/4" mdf initially just to get everything in place. The midbass was a little weak.
When i made my baffles out of 3/4" mdf, about a month later,everything improved dramitically!Now i have strong midbass, and the woofers are not moving as much as before, even though i now have more midbass, and everything sounds cleaner. Although i had to make some modifications to make everything fit, in the end it was worth it! Bottom line, if you need more midbass, and have the patience, find a way to mount your door speakers in 3/4" mdf! It is well worth your time and effort!

 

hmmm, i guess theres something to be said about mass huh? Try some modeling clay around the speaker too, i hear it does wonders with the clarity also. Is your door deadened with something like dynamat (eww) or any sort of sound deadener? You'll hear a huge improvement on the midbass and clarity from doing that too.

 

ROCK GUARD lmao cheap and works to take out the tin sound of the door hahahah thats if you dont have cash for the good stuff. 20$ and your good

 

, i think i used two cans in one door once - WOW that stuff worked when built up a quarter inch ha ha. but seriously, it works a little bit for what its worth.

 

of course lol im not rich so i have to do with the little ive got. just by doing that in my doors it did work. didnt seal up the holes in the door of course but ya lol

for a few bux it helps. AND a solid baffle

energy speakers dont have much midbass and i got them banging down to 50hz now. with nice SQ
