?'s before Sealed Q 18's

[WrenchGuy 10+ year member]

Gonna build a sealed enclosure for 2 Q 18's.

2004 Tahoe. Subs back or up? I'm thinking back but I get close to the lift gate that way. 21 inches high keeps the amps under the headrest.

I was going to start at 8 cubes per and let displacements knock it down from there. That keeps me the best distance from the lift gate.

I'll pretty much have the amp rack right on top of it.

In for the answer, but I suggest you build 2 boxes and let us know... lol

After all displacements I have 15.3 cubes and 7.65 cubes per.

Thats with subs back. I might go and get some wood tomorrow but I wish had some clamps close by.

Looks like I get to use the high end of the enclosure.

wow that's big. Doesn't Fi recommand these size for ht only? you could runs yours ported.

I did try one at 7ft sealed and it was sounding great. The box was ported prior

I have them ported right now. Thats in a 16 cube at 33. I want to seal em.

At a little better than a sheet I think it would be worth doing anyway. I'm just going with the room I have.

It takes 3 more inches off the gate where the port is now going sealed subs back.

Alright, before I go get some wood does anyone else suggest I shrink my chambers?

I think having the room and getting the low end out of the subs is a plus.

I didn't E- Mail Nick but recommended is 4-8 cubes. Nothing stated about what application.

why dont you just shove your port full of shit with the box you have now and see what it sounds like?

Subs would be up. I don't want to tamper with it either.

subs back will just rattle your car regardless of how well you dynamat IMO subs up at the back corner would sound just as good as not give you the extra rattling which can hurt bass performance

Looks like I'm gonna have to experiment.

 

[WrenchGuy 10+ year member]

Well I got some wood. Time to build.
