It's funny, but when I measured the hole in my '00 SVT, it was exactly 5 1/2". What gives?

I think people refer to it as a 6.5" hole because that was the intended speaker size, not the hole size.

Arg... I guess I don't get this...

I take an 8" woofer, and mount it on a piece of MDF with an opening of 8". Then I take that whole 'assembly' and mount it to a 5 1/4" hole? What's the use? Won't the small diameter of the deck hole cause most of the bass from the 8" to get bounced around back into the woofer, not into the cabin? If anyone has done this (and I know some of you have), please please please post a pic of it.

actually, if you measure most 8" subs, the actual cone area that moves is only about 6.5". The hole will block some of the sounds but not all.

I measured 6.5" exactly because a 6.5" speaker will fall through on my 2000 SVT. But now it's covered up so I'll never be able to measure again. That's the metal, right?

So, I have no idea what i'm talking about...it's not the first time.

APT CSVT,
How'd you mount your 8 to the deck? do you have any pics? I think Jazz would appreciate them.

Jazzman,

I just called my brother that works in my building to have him bring his digital camera to work. So, I should get some pictures posted either today or tomorrow. I'm not taking it down though.

So far, what Dave has said is what I've done with great sucess. The 3/4" MDF board looks like a spacer, but was done because the particular woofer I got has a large excursion (Xmax) and might have hit the metal a little. However, the metal itself will not block too much sound because bass is less directional and doesn't reflect, as stated is some earlier posts. In the same respect, though, the glass right above the package tray will not reflect it much either so it is heard from outside the car. (The insulation in the Contour isn't great because I hear most of the frequency band outside my car at moderate sound levels.)

I think this is how the woofer/MDF/deck is attached. My brother worked on this mostly as I was working on running the wires/replacing the head unit. From bottom to top installation. He used silicone seal between the woofer and the MDF board. Then just drilled pilot holes in the metal deck for some metal screws (with points) through the woofer mounting holes, through the MDF board, into the deck. I think there were eight screws used. Oh, I think a piece of foam was placed between the wood and metal for vibration as well.

I'll go take the pictures at lunch time today if my brother brings the camera in. If he brings the cable to copy to the PC, I can post them today, other wise, tomorrow. When we go take the pictures, I'll verify the procedure above, and post amendments as required.

Not true. You've been very helpful to a lot of people on the board, including Jazzman. He just wanted some more details that only are thought about if you actually do it.

Note above was work in progress. I'll expedite pictures. so they are posted either today or tomorrow.

If only he lived in Detroit...

No no...i was just making fun of myself.

Hey guys...

THanks for all the help you're providing and have provided. Pics of your deck install would be very appreciated, APT.

Oh -- I'm in talks with someone about the new sony mp3 deck that might be coming to market soon -- waiting on an email reply, I will make an announcement when I hear something concrete. Shh... Keep it quiet! :-)
