Question about power, and impedance.

[ford302redneck 15]

Play 10 Hz. at maximum mechanical limits, then play 40 Hz. at 75% xmax, which do you think is more loud?

Your problem has far too many variables to answer correctly...

I know there is a lot of variables, not really looking for a exact answer either.

More along the lines so I could come up with the conclusion.

I may try what you said, can you explain more though?

[ford302redneck 15]

Hmm, since its rated not rated for 1 ohm its feeding dirty power, causing the coils to heat, causing impedance to rise dramatically, decreasing power. just a thought dont knock me if im way off.

How do you know its dirty? I cleaned everything before I installed it. And the wire I have is suppose to wash all the dirtiness away just incase I missed some.

Just kidding man. I do hate the word "dirty" power though, but this is because the local idiots use to say it all the time and had no clue WTF it meant. And claimed a highend amp as dirty power, and a cheap POS as good "clean" power.

I meant slutty power

[ford302redneck 15]

Oh I like slutty power, that's the best kind to have.

hmm try taking your dustcap off maybe at 1ohm your just pushing to much air for it to be loud .................only thing that makes sense

Damn, why didn't I think of that?

Will try this later and report back. Who needs a dustcap? That can be another port for my box. Heck the cone will act as a flare for the port and help move the air in and out. Great thinking!

Joking aside, I am kinda curious on seeing a video.

[ford302redneck 15]

Will do Tomorrow. I changed it back to series and now its playing normal.

At one point I thought I lost a coil because I messured the impedance at the amp and got 1.4. Then took the sub out and both read 1.4, so I tried at the amp again and got .8. So I assume I check it to quickly or something.

I'll be sure to try it again tomorrow and video it this time.

[duanebrow 6]

I'd guess the amp doesn't like the one ohm load!

[Beandip 3]

Bump for video?

[ford302redneck 15]

I totally forgot all about it. If you really want one, I can do it in the next few days.

I haven't even messed with it after this thread.

[Beandip 3]

Up to you. I was just curious to see what it was doing.

If your bored, go for it, if your busy then forget about it.

[ford302redneck 15]

I'll see what I can do.

Sounds similar to a problem I had before with my old MTX 5500s in a sealed box off of an Alpine MRP-M500. I would play this song: -go to 2:45

Let's say my max volume was 25... at volume 18, the sub would move an okay amount and played at a decent volume. If I put the volume around 25, it actually seemed to get a little quieter but it moved a ton more.

To me, it just sounds like a good case of clipping. Clipping we all know increases the coils temperature, and that increases impedance. So say you are wired to 2.8, you may see 4 ohms final for whatever frequency. If you are wired to .7, you might see 12 ohms final if you are clipping. I know first hand the problem you are having, but I'm just taking a guess at why because I always wondered myself.

And why are you wired to .7 when the amp is only rated at being 2 ohms stable?
