Just wondering what the advantages/disadvantages were if i upfired (2) 15" subs n the trunk of my maxima. I don't have the clearance under the rear deck to fit a 15" unless i cut my torsion bars, which i'm willing to do, but didn't know how an upfiring sub would be compared to a rear firing. All of ur opinions would b greatly appreciated.

i bet the difference would be minimal... has been done lots... go for it

(also, i have a blazer, wait for someone who has a trunk to comment)

****** in my max. bes output was rear facing. Never had dual 15s firing up. THe subs i did upfire were

2-10l7s sealed
1- 12l7 ported
2-1500spls sealed
1-1500spl ported
3 1500 spls ported
1 polk momo 10

with the box on all of those the best was firing to the rear or all the way at the back firing into the lid. That was the best in car response. my max is a 98 dont know if you have a 4th gen.

Yea I have a 4th gen...mine is a '96. ***** to hear that they didn't perform well up-firing :(. I guess I need to cut the torsion bars, and do an in trunk build.

my subs fire rear but my ports fire up and I actually get louder to the dash then when I had the ports firing to the rear. direct shot to the old 6x9 holes to the cab of the car, I bet speakers firing up would have the same effect as long as you give them room to breathe.

Make sure teh box is the width of the port away from the trunk lid when facing em up. Its less cancellation that way(so i hear).

i have 2 15''s Alphasoniks and they are firing up in a 87 Regal...its the loudest system ive owned..but i also have alot more room in the trunk then you do so i imagine this plays a big role in it

Do subs up, port side (towards the pass or drivers side).

Has worked well in alot of applications.

You have any pics of this setup? Seems like I have read about this setup n another post about a Maxima. U know cubes the enclosure is? I was thinking I may be able to fit 7^ft, but only if it was built n the trunk, and I don't have enough experience to take on that task.

In my BMW had the Sub rear to Trunk lid, with ports firing up, through rear deck.....the pressure almost killed me....literally. With the seat down....amazing.

I too heard about ports through an armrest, but was in a BMW.
