Miswiring subs

[Scarenius 10+ year member]

Until today, I have had the impression that at 8 ohms, my peticular subs are 4 times louder than at 2 ohms.

Then, I had some insight.

If I miswired my subs, amp + to vc + to vc -, and amp - to vc- to vc +, will I basically get no sound, soft sound, or will it have no effect?

if you miswired the impedance so that it was lower than what your amp can do safely, you will get no sound. If you wired it higher, you will get very little or reduced output...

I've done my amp 1 ohm bridged before. It works, impedance has nothing to do with it. I think one of the pos/neg voice coil markers could be mis-marked on each of my subs. I personally would not be surprised, considering where I bought them. Tomorrow I'll try wiring them against the marked polarity and see what happens.

haha just start connecting wires where you wish and see what happens!

+ and - doesn't matter as long as you do all of the subs the same... if you wire two subs the opposite ways they will cancel each other almost completely out.

i did that before and was like wtf?

Ok, ok. I think I didn't state this one right. I know all about wiring 2 seperate subs against each other, and the results. I'm talking about wiring a single DVC sub against itself.

I figure, if anything, it'll put out no sound, or be really quiet. I am going to attach it to my JXP460 amp, since I don't think horrific miswiring would hurt at such a low power input (40 watts, maybe..).

It'll only be hurting the amp if you mismatch impendance.

Those are you only wireing options for 1 sub.

This is one DVC woofer. dual 4 ohms. Its simple buddy.

If you wire a single subs coils out of polarity with each other, the result should be no sound (since one coil is trying to go forward by the same amount that the other coil is trying to go bacwards). If you get sound, any sound, then you should be worried because that means that one coil is "stronger" than the other for some reason.......and for all intents and purposes, it shouldn't be.

The exact answer I wanted.

I tried this, earlier today. The sub didn't do anything. Pure silence. This does, however, hurt the sub. The sub got hot pretty quick. I didn't let it stay that way long. I put them back at 8 ohm, their loudest impedance, again, and called it good.

I need some new subs.

So are you saying you think one terminal is mislabeled, or no? I'm assuming dual 4 ohm subs? If so, and the amp can handle the impedance, how are you figuring 8 ohm is the loudest?

 

[Scarenius 10+ year member]

I *thought* one VC one each sub was mis-labeled. I figure my subs are louder at 8 ohm because I wired them at 8 ohm, tested them, rewired them at 2 ohm, and tested them again. They are noticably louder at 8 ohm.
