Which way to fire the subs........???

[espguitarist91 10+ year member]

Well, im soon going to be building a sealed box for four infinity 1240's and im not sure which way to make the box. Im pretty sure i can make it firing towards the back being that its going in a 91 deville and the trunks huge. I believe it would be much easier to make the box upfiring though. Is there any advantages/disadvantages to either method. I had one 12 firing towards the back and it sounded real good, so i dont want to lose much output/sound quality if any. Thanks

don't upfire in a trunk, that's your weakest wall, most flex

push up against seatbacks, fire back, or push back to the rear of the trunk and fire forward

I plan on firing up in my hatch. I really don't see whats wrong with firing up in a trunk either. I fired down in my jetta, and up in my truck. Just curious.

I figure it may be better i can drill holes in the rear deck to allow more sound to enter the cabin. Hopefully my theory is right even though it will be sealed.

Does it have speakers mounted in the rear deck? If so just take those out.

ya i do but id rather keep them in. They were 100 bucks so id rather not waste them. Plus they add a little midbass.

Would taking out the rear 6x9's make a huge difference in bass in the cabin and/or midbass?

Thanks

DEFINITE YES, in my case that is

 

[espguitarist91 10+ year member]

meaning more bass or loss of midbass?

If you have a good front stage, it shouldn't matter. I don't like rear fill regardless, but that's personal opinion. I have my sub upfiring in my trunk now with the rear speakers out. It also gave me more headroom for the box.

Ok, well sealed i dont think it will make that much of a difference, but im not sure. I think it will be easier to make the box upfiring.

Thanks

I have tried just about every imaginable way in a 02 cavalier when I had it and it sounded the loudest facing back, even though it rattled the most that way. Sounded like shit upfiring and lost alot of dbs due to flex. Sounded the cleanist facing foward. Just my .02 cents. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Well the cars a 91 deville and the trunk is pretty deadened by itself. Never hear any rattles, but maybe ill just make it rear firing.
