subs louder with trunk open


Recommended Posts

i'm running 6 10's in a 6cube ported box in the trunk of a chrysler LHS. the trunk is a total of about 11-12ubes. box is ported through rear seat armrest. the problem i'm having is that when i play music there isn't as much bass as there should be, but when i open my trunk, i gain alot. i'm a noob so i'm not sure what could be causing this. could it be that there isn't enough airspace in the trunk for the 6 10's, or somethig else? i was running 2 15's in a 9cube ported through the armrest and it hit harder when the trunk was closed, that's why i'm not sure if the airspace is a problem. please help with this problem. thanks

i had this once. had to do with vortex theory

essentially with the trunk open the subs had more air to move and created a louder score. however this was because of a mistake of mine and it probably would have been louder if i had done the box correctly

show me how everything is setup in your trunk

sorry, i can't get pics right now, but the subs are 3 firing up and 3 firing back. i was just outside playing it, and a few of the subs were getting hot and a few were staying cool. what could cause that?

Having them like that is probably the reason, have them all facing the same way.

I'll admit, half way through sanding that fiberglass in the rain and cold while I was all itchy I was definitely starting to question why i was doing this haha

out of phase?

might have to do with 3 firing up and 3 firing back (being in a trunk), thats prolly where your cancelation is coming from

so just rebuild my box for them to all fire up and that should fix my problem? does anyone think the airspace could cause another problem after i do that? asking cuz i know 6 10's moves more air than 2 15's

out of phase?

You have around 11in^2 of port area per foot. You might want a little more if possible, but that shouldnt cause your problem that your having now.... Do you have a DMM?
