Has anyone done this? I hear alot of people say throw away your 6x9's. Anyway, there is this guy around here that is doing this, sounds intresting. The reason for doing this, im guessing, is better mid-base, any opinions, fact or poo.

It's do-able, but you have to bust out the power tools and cut away some of the sheet metal back there. Most people take the easy route and put 6" components in there. They will work very well as mid-bass with a good EQ.

Must agree, It would take too much time and fabrication to do that. That's my 2cents.

Unless your going to make some sort of sealed box to fit in the pillars, you'll be limited to 8" free airs, which are a waste of time and money.

6x9? 6x9? You guys have 6x9's in the sailpanels??

Hehe, just kidding... but my 86 (or 88? 89? we don't know ) SC came with 6 1/2's in the sail panels. Looked like they were stock, too, because the plastic panels had a round hole and the speakers were at least a decade old (and blown). Anyhow, that's at least evidence that it's not always a huge deal to put in a different size speaker!

:lala:

I did it in my firebird. I didn't have to modify the sheetmetal on the car at all. I removed the 6x9 bracket that was bolted to the chassis, and did all of the modifications to that. I had to widen the hole for the 8" frame to fit, then I had to build an adapter to fill the holes where the 8" sub couldn't cover. I did it in a free-air application and ran them from 60-300hz. It worked out pretty well as a midbass, but I don't think I'd waste my time trying to get low frequencies out of it unless you want to fiberglass an enclosure in there.

I like the idea of having hidden bass but i have infinity kappa 6x9s and they sound really good. The only way to get your spekers to sound good is to get an amp. I think a decent amp sounds better that the power output from any head-unit.

Jim85, have any pics of that install? Sounds interesting as I'm not into the whole assymetric speaker idea. I prefer symetric speakers because the sound field is usually better.

Nah, I never took pics of it.


What do you mean symetric speakers? Are you talking about round vs. oval shaped? Most quality oval shaped speakers use a cone that's rigid enough for it not to be a big problem. The biggest issue is that oval shaped speakers don't have a smooth dispersion pattern, but that's not really a problem as long as they are both oriented the same way. If you had one mounted vertically and one mounted horizontally, and listened off-axis, it might be an issue, but as long as they're both mounted in the same orientation, it's more or less a non-issue.

That's not to say that a 6x9 will have superior sound to a 6.5" round driver, but the added cone size of a 6x9 can sometimes offset the advantages of a round driver. It boils down to each individual speaker design more than its shape. Listen to everything and base your decision on the sound quality... not the shape.

definitely do it outside the car.

it's actually not that hard to refit another size speaker in there. the best way to do it is to go down to home depot any just buy some 10" square (or whatever size the original steel panels are) x 1/8" aluminum or steel sheet stock, and just cut a new hole. it's not too tough with a drill and a dremel or a decent jigsaw.

i made new adapters with my rotozip and some mdf you can easily install an 8in speaker in there personally i noticed a nice difference when i switched to 6.5's
