building box that fills trunk top to bottom bad idea?

[down_shift]

So after doing some measurements in my car, a 94 seville i found out I can fit an 18" but it would pretty much cover the trunk top to bottom.

I guess my only question is if I fill up the width as well would that block a lot of the sound\bass from entering into the car.

I'm looking at an sa 18 ported or possible an sundown x 18

Any imput is appreciated Thanks

Is the baffle area behind your seats big enough to wall it? If so, that would be your best bet (assuming you have enough volume for the box)

Can you explain exactly what the baffle area is??

Lol sorry, im guessing you mean doing something like this?

If so than yeah that should work, prolly line it up with where the rear windsheild comes down?

But I'll start researching those types of builds thanks

But if it would be best to have the board pretty much flush against my back seats i don't think I have 18" that far back

Update: Never mind that would definitely work

I was thinking something like this with sub and port firing directly into the cabin. Make sure you seal around the edges

Ahhh that makes sense, Thanks for the pic. I could possibly do something like that but it wouldnt be actually into the ca b of my car because of the caddy's awesome electrical and Bose setup.. I'll try to upload a pic

Well thats gonna **** lol. Yeah if you think you can do an 18, you most likely can only do a 15. Ports takes up a lot more space then you can gauge with your eyes.

IDMAX 18. IB that Bitch

Haha that setups ******!

But yeah I'm still trying to install a new head unit with the weird *** Bose system it blowsss lol but good to know I appreciate the feedback

that pic is kinda a close up of my trunk, its a big trunk if i did my math right I easily have 9 cf of space but if I try to do a similar setup to that DC audio I think you're definitely right with going to a 15" instead

I just found a super clean idq 15" coils perfect for 60$!!! Offered the guy 100 to ship but he won't....

But I don't want to wast anyone's time considering I haven't picked out a sub yet.. I'll likely just grab the best deal I can find and will shoot for a 15 to leave my options open.

Thanks guys

L x w x h but you will have to subtract 1.5 from each for wood thickness. Get the cubic feet then subtract the space subwoofer will take up and a rough estimate of 20 percent of the enclosure volume for the space the port takes up.
