I've got a kicker 12 cvr dvc and just a generic box that i hate and will burn when i build my new one, but til then i have to use it, should i have the sub facing into the box with the magnet on the outside or on magnet on the inside?

I was going to make a thread about this same topic. I think most of the time people put the sub facing out, so that the magnet is inside the box, but my head unit has a sub option to pick if your sub is facing in or out, and I was going to ask what the difference is and how choosing either one changes the signal. It definately sounds different when I choose reverse (sub facing in), but I guess it sounds weird because my sub isn't mounted like that. At any rate, sub facing out takes up less room.

yea but with this pos-i mean box i lost my trunk n e ways so either way doesn't really matter

How big is your box and sub?

 
Rep Power: 312

it's a 12 inch kicker cvr and the box is aboot 1.1 cubic feet

having the sub facing in or our does 2 things and 2 things only.
1.) Changes the internal volume of the box. your 1.1 cf box with the sub facing in is actually like .85 or so because you have to subtract the volume of the sub. and it would be just slightly bigger with the sub facing in. You'd have to add the small amount of gain from where the face of the box would be compared to the curvature of the cone. There is much less of a gain in box size this way than the loss the other way cuz you have to subtract the whole sub volume the one way.
2.) Changes the phase so you'd have to reverse it on your deck or switch the wires around, NOT BOTH.

i have mine facing up...is that bad? or how does that affect the sound

he's tlaking about the sub facing into the box or out of the box not what direction the box itself is facing.

if you've got room face it in to be a little different and get more internal volume.

What does "phase" mean, as in, "reverse the phase?"

 
Rep Power: 310

Real simply, In-phase means that the voltage rises and drops of two signals occur exactly in time with eachother. Reverse phase means that the phase is reversed 180 degrees from what it was. So the drops occur when the rises where previously occuring. Basically your speaker pushes out when it previously pulled in.

Speakin' of phase J187, my speakers are faced out wit magnets inside the box...and i switched the Phase on my amp to 180*...what im askin is do u think it will do damage to the sub kuz it seems to hit alot harder in that mode for some reason...let me know man....

PaCiFiKbAllA it wont damage anything. And it will probably look really dumb just having a square box with your sub magnet facing out. It will probably make it fall over as well.

thaz good to know...thanks man...

Phase refers to how a speaker is powered and moves according to that power. Essentially a speaker moves in and out. A speaker moves out when power is applied from the + to -, and then moves in when power is applied from - to the +. Amps move speakers by actually swapping this power back and forth very fast.

What this means is there really is no wrong way to wire a speaker. But what happens when you have more than one speaker is you want them to both move in and out together at the same time. This way the bass from both speakers "adds" up together. When speakers are both moving together they are considered to be "in phase" w/ one another.

Ideally you want all the speakers in a system in phase w/ one another. Occasionally due to funny waves and acoustics in certain cars subs may sound better out of phase w/ the rest of the system.

thanks regularjoe...good info to have so i can pass it on....u da man!

Basically the only thing that is going to change by fliping your subs is that it will give you a diiferent display when you open the truck to show off. Unless you have some exterme dollars invested and are going to compations then truning around your subs in a cosmetic desion. But the best thing to do is just try it and see if you can even tell a difference. you have to make that call.

I run my sub in reverse mode with the
magnet inside the boxe because it sound
way louder. You will not damage anything.

my amp doesn't have a phase switch, any way to change it or am i screwed in that department?

 
Rep Power: 346

A lot of head Units have a phase switch too.

i doubt mine would, i hate it, blaupunkt orlando cd72
