Okay I have a mild sound set up in my 91, and i can't get a good sound from the 6x9's. i've used 3 different sets, and they all seemed to sound crappy. (boston's, Pioneers, and Eclipse) I put the pioneers in my girlfriends Olds, and they sound great on a factory deck. I know it's prolly because of the trunk acting as an enclosure. So my question is how can I get my pillar mounted speakers to sound like that? Poly fill, take out the baffles...what? Please help.

 

ive got sony X plods and they sound great.

 

you could try spraying expanding foam in the cabaty <-- spelling just don't use the super expanding stuff or you'll have foam takeing over your car.Seal up everthing inside put some polyfill and hook up a small amp and that should be a good start

 

i use infinity 6X9's

 

I also have the infinity 6x9's and the highs sound great, but acoustics of the car just arent gonna allow the speaker to sound that much better, i've tried a lot of stuff, i just stuffed an old t-shirt behind the speakers, and it helped some, but isnt the speakers, its the location

 

i'm thinking about taking ABS and cutting it to fit a mid bass 6.5, and a tweeter, and filling it with poly fill. Anyone tried this?

 

Dude, if you can find Memphis 6x9's, get them. I use them, and I wouldn't trade them for any other type. You might also want to try running a 60 watt rms amp to them.

 

Buy 6X9 Boxes and place them in your rear tire well. They sound 10 times better than when they are in the normal location. I have been fooling around with the location for months, and it doesnt get any better unless you have a custom instalation. I have Sounstream tarantulas in my hatch and they sound pretty good.

 

Okay, i think you missed the point. If I wanted boxes in my trunk I'd add a sub. So I'm trying to figure the best possible sound from the least amount of weight. Thats why I am considering the Custom 1/4" abs plastic plates for a component set on that location. Sound deaden the location and add poly fill. Since a 6.5 can sound excelent in a door, hopfully it will sound good there to. I had a big system in my Iroc I sold, and it was too much. And i got sick of chasing rattles thru a 17 year old car.
