Side firing or back firing?

[NMLegend19 10+ year member]

Building a 5.5 cu ft box and sticking it in my Acura Legend coupe trunk. lol don't ask it'll fit. well the front wall will be like 2 inches away from the very back of the trunk. should I still make the port facing backwards or should I make the port firing sideways into the side of the trunk?

usually u want back and want the same clarance as port opening so if you have 4" you want 4" from trunk wall to port or it can choke it. ive seen a few guys that have been doing side ports and doing high numbers but ive never done them this way.

You should be able to make more than 2 boxes that size with 200 dollars.

I can build a 5.5 cuft box with one sheet of mdf, 25$

2 boxes = 2 sheets = 50$

Where is the other 150 coming from?

where are you getting 3/4" mdf for 25 bucks?!?

and my dimensions are 12x35x36 and I worked out a cut sheet and I'm gonna need about 1.75 sheets per box. double baffle on the top piece.

Why would you carpet if youre building test boxes?

Sure you'd need 2 sheets a box?

I have a 6.2 cuft box after port displacement and only used a sheet and a quarter sheet.

I say back unless the box is too big for your trunk.
