Quick question, extreme flex/sound deadening

Efficient box vs a less efficient box that draws more current?

I dunno man. Box science is something i know very little about. Alls i know is my last build, was a single 12 Rockford T2 and it also was pulling wayyy more power.

This box, obviously something is up. Only thing we did yesterday was hook up a different sub in a different box, and back and forth. The power output was drastically different on my friends other box. So i don't know. Thats why i asked

That would have absolutely no effect on what you'd be clamping I don't think. You clamp before the box so....

Wowwwww....

Impedance rise affects what you clamp.

Seriously.............

By that logic, it wouldn't matter if his subs are wired to 1 or 8 ohms, because they're after where he clamps, right?

I' am saying the reading he's getting on how much his amp is putting out wouldn't have anything to do with the box. You do understand what clamping is right bro?

No hes right man. Clamping off the speaker wire is the power flowing thru said wire,which is connected to the woofers. While power is applied, the box in which the woofers are in then... i dont know how to say it... "absorbs" the power. Obviously if im getting ridiculous impedance rise, the only thing that can contribute to that is a box. Boxes and poor connections cause rise...

Did you put your friends sub/box in your truck with your electrical or put the amp in his? If so what's his electrical?

In your pic the speaker wire looks small, what gauge wire is it? Could have an effect on box rise.

For the back wall vibrations, I would take the plywood off, fill any voids with deadener until your flush with the metal frame. Then apply liquid nails to the metal frame. Then reapply your plywood. I bet right now the plywood is hitting your back wall and creating vibrations.

yea sure whatever

You are an absolute idiot. Do you know what clamping is?

Let me spell it out for you...

voltage x amperage = watts

You put leads on the output of the amp and set one meter to volts a/c.

clamp the a/c amp meter on one of the wires coming out of the amp.

Set both to peak/hold and play your music or test tone

Multiply the results to get wattage.

In order to have amperage, current must be flowing through wire. Less resistance equates to more current. More resistance equates to less current.

You know why wiring your amps lower makes more power? Less resistance allows more current to flow. When your amplifier's output stays the same, more current yields more power.

You know why you can't wire amps too low? Internal components can only handle so much current.

PS. Your avatar pisses me off

Yeah whatever he should keep listening to you because that's obviously working. Please go troll the Thunderdome. Talk to us when you actually have a working sound system btw.
