my friend bought this sub that he is putting in his car when he gets one but he said i can have it til he gets his car its a interfire, i have never heard of them before. im pretty sure its a interfire IFB-15D. i wired it up and listened to it free air and it was real quite and didnt move much. would a box make it alot louder? also i need a box design if anyone wants to draw me up one

it next to alpine type r 10

Subwoofer's work in essence by moving air. Obviously you need power for the speaker to work, but without a box it will always be quite. I understand you may be new to this, but in simple terms, drop it in a box, and you will be surprised at how easy your question is answered. This applies to all speakers.

ok thank you everyone for clearing that up for me. i knew it would make it louder but i didnt know by how much. but i need a box and i can build it if i know how big to make the pieces. can some one make me a box design? i would like it to be about 3 to 3.5 cubic feet sealed. i will have measurements up tomorrow of my trunk but this is the space i have to work with

I like that you answer questions and try to help people put.

Shows that you aren't all about business and want to help the little people.

Very cool
