Volume of under seat sub enclosures

[wheela]

Not sure if anybody here gives a flying frog about car stereos, but thought I'd share this for the greater community.

Background:
I'm planning on sealing these up and running different speakers in this location as mid-bass (actual subs will go in the hatch). For my application, I needed to know the internal volume.

Method:
Results will vary depending how you seal them up - details how I measured volume are in the pictures. To measure volume, I bought a shit ton of 0.55" diameter marbles and a 1000mL graduated cylinder. I filled the enclosure up with marbles, then dumped them out and measured the volume of dumped out marbles with the graduated cylinder.

Results:
3.3 Liters
(filled to 1000mL 3 times + another 300mL)

Enjoy!!

Which amp will you use? Been thinking about doing something similar to you Plan and installing the subs into my rear seat delete thingy

I'll be running the underseat mid bass with 2 channels from a JL HD600/4 amp (4 x 150 watts). I got some Morel TiCW-634ND to run down there I'll be using a Mobridge DA-G2 PRO MOST25 for interfacing the amps to the head unit

How far along are your system plans? Do you have any components selected yet?

Looking forward to the write up…I went with Audiotec Fischer Match 1k with their MOST bridge …I suspect the underfloor subwoofer volume on your car is about the same as the subwoofer mounted on the rear bulkhead on E89s..

I literally didn't do anything since coming up with the idea . My turbos just broke and while changing them I also upgraded the in and Outlets and intercooler and what not, so I hadn't had any chance nor money to start this project. I hope to get to the subwoofer project around Christmas time next year
