volume of sub box
Does it make a difference what shape your subwoofer box is in, as long as it
has the appropriate volume of air/space? To limit the amount of space taken up in my trunk, i'm looking to go from 2-12's to 1 and would like to custom build a box that is the width and height of my trunk, but only as deep as it needs to be. Does this make sense? Side note: how much bass will i lose going from 2-12's to 1? I'm running an old old alpine v12, 2 channel. Can anyone give me details on how to hook my amp up to the one sub? I believe now it is bridged to both subs. It's just been so long since i was into this stuff. Maybe you could point me in the direction of a website that will tell me the best way to hook the amp up? Thanks. Sorry for the stupid questions. Cut |

A wide and shallow box will need a lot of cross bracing to keep the frequency response smooth. Large top and bottom panels can move a lot of air with just a little vibration. Hardwood or even metal would save you the most trunk space. Particle board will have to be pretty thick. Whether or not the 1 speaker box looses bass depends on the tuning. You might loose nothing if the new box is tuned better than the old one. You could loose it all if it's tuned worse. I built some extremely quiet subwoofers when I was a kid and not using speaker enclosure calculators. I don't know about the wiring without more info. |

Thaks kevin.
Are you suggesting it might be better to go with a standard "cubed" size box and just throw it in the corner instead of a "long and shallow box"? Also, here are the specs of my amp, per the manual. model: alpine mrv-t500, 2 channel rms power per channel into 4 ohms: 50w rms pwer per channel into 2 ohms: 100w rms pwer per channel bridged: 200w I "think" it is bridged now but, to be honest, i wouldn't know how to tell. The amp is running 2 kicker 12 inch competition subs and i "believe" they are 8 ohms each. I guess i really need to check all of this before asking questions or just take to a shop and have them do it. I just can't see spending much money to do this. Then again, i don't want to screw anything up. Thanks for the input though. Cut "Kevin McMurtrie" wrote in message ...
