sub box
 

hey i'm looking for some help with a sub box, sub is in a box too small right now, so need something bigger, i was looking at ported, i can't really find the exact specs for my sub, these are the specs for the same make 15 inch at "2000" rms but mine is "rated" 5000 its impedance is 1.5 ohms, but I would assume the mounting depth should be same or shouldnt change much

Diameter: 15 Inch
Impedance: 2 Ohm
Sensitivity: 90.6dB @ 1w/1m
Mounting Depth: 9 3/8"
Mounting Diameter: 14.2"
Vented Box: 5 cu/ft
Port: 48 sq/in 13.0" Long
Sealed Box: 2-2.5 cu/ft
Weight: 57 lbs.

What brand of sub is this and your vehicle?

this is actually as specific for my sub as I will find

5 Cubic Foot Optimum Enclosure: Vented 40Hz - (2) 5" round x 9.5" deep or slotted 10" x 5" x 9.5" 50Hz - (2) 8" round x 7"

its in a 2001 camry

i just found those specific dimensions, pretty much 1 minute ago

Measure your trunk and see your maximum dimensions, factoring in you will need to slide the box through the trunk opening. To make it easy to build I would suggest using a 6" aeroport which can be purchased here: Creative Sound - Product Details

You essentially build a square box and make 2 round circle cuts for the port and subwoofer. I can help you with tuning once you figure out your dimensions.

cool thanks man I appreciate it, I was kind of thinking of going with this design just for the looks https://www.caraudioforumz.com/attac...ine=1401983226
but I suppose a square box would be easiest to build?

I have about 19.5 inches height (max) anything higher won't fit,
so I'm thinking 19.5 height, 30 width, 15 inch depth, will give me 5 cubic feet, does that sound about right? or am I way off
for a ported box

19height x 30 width x 15 length gives you about 3.9 cubes net for a sealed box not factoring in port. It seems 2 10" woofers would be ideal in your trunk.

how did you get that? I plugged the numbers in two of those online subwoofer box designs
