8" mids in 97-03 grand prix

Has anyone run 8" mids in the stock door location in a 97-03 grand prix? I was thinking of adding another pair of silver flute 6.5's to the doors, but that would require a fair bit of cutting and glassing. Was wondering if I could fit an 8" silver flute mid in there.
 


Hey somebody else that runs silver flutes! I love mine. I'm running 6.5's in my impala. I'm going with 3 8" of them in each door in a few months. You're gonna have to do some serious fab work to the speaker pod to get an 8" to fit behind the door panel and not rub it. And even that they're definately not shallow so you may have problems with the window. That said, I would totally give it a try
 
Yeah I love the silver flutes for the price. I've already cut a round hole in the door panel where the 6.5 is and have black speaker mesh wrapped over the hole. Looks alright. I could just cut that hole bigger for the 8". I had the door panels off the other day so I kind of answered my own question. It can work.But the only reason I want bigger mids up front is the 15" fi bl is tuned to 31hz, doesn't like the high notes too much. One day I will do a sq oriented substage with 2 15's or 2 12's sealed. For now I will enjoy the low lows. :o
 
I know exactly what you mean. I have a 15" eclipse titanium tuned at 28 hz and it gets the killer lows but the 2 12" Boston g5's sealed I have in the gp just sound so good. I'm not sure what I'm willing to sacrifice at this point, the low lows or the sq. I'm wanting the 8's for partly the same reason, but the other reason is that given their sensitivity and power rating, they should almost be twice as loud as the 6.5's. I've been considering trying to make their recommended ported enclosure into the door. Although if anything they will at least be in a sealed enclosure. I think with what you've got on the door panel, getting an 8" grill may be easy to mod the door panel with. Then just cutting out several mdf spacers to set the speaker out from the door, should work fine. What do you have for tweets?

yeah I think I should be able to get it to work. I've been running these tweeter for the last few months :

Vifa NE25VTS-04 1" Silk Dome Tweeter 264-1034
 


i have them crossed at 3k i think it's 3.125 or something like that at -12db. They are off axis mounted up high in the door panel. I wanted to mount them in the a pillars, but I have a triple gauge pod so it doesn't work there. I really like them, I haven't had a lot of tweeters to compare them too, mostly ones that come with components sets. But imo, they are really smooth and laid back. Which is what I like. I don't like bright tweeters
 
I don't like bright at all either. Can you post a pic of your door? In my impala I'm making a pod to go on the dash in the corners of the dash as window.
I've also found that the mids sound a lot better on axis as much as possible to me. Mine aren't angled up towards me enough, the sound seems to be able a foot too low
 
i have them mounted on a flat 3/4" birch baffle right now. so it's a fair bit off axis. I've been thinking about making an angled baffled, like 1-1/2" angled down to 1/4". to get the woofer more on axis. That way the flutes will play smoother to 4k, and I could cross the tweets higher and not split the vocals between two drivers
 
You should definately angle them but idk if I'd cross the 8 that high. Seems to have a pretty big peak. Idk how low you can cross those tweets without breakup but I'd maybe try 3k on the flutes and 3.5k on the tweets and with the 12db roll off it should still cover the gap nicely

that would be for the 6.5's, haven't bought the 8's yet. just thought I'd try them more on axis since the door panels are off and doesn't really cost anything other than the time to cut the baffle.

edit- I'm almost leaning towards holding off on the 8's for now. Kind of want to try a 3 way active setup down the road.
