an idea, check your tensil leads one coud be broken

I said it once... Ill say it again... if the voice coil is SHORTED... it means its still connected... and once you get it hot enough (turning up the voulme giving the sub some more juice) the coil shorts out again...

Happened to a friend of mine. Take the sub out and use a DMM and messaure the coils... and check the tensel leads. They are still connected but just check them for dark spots.

That makes zero sense. But whatever.

If the coil was shorted the amp would never turn on because it would sense a dead short. (no resistance, "OL" on the DVOM)

A dead short, is like taking a paperclip and putting one side in the positive end of the output stage of the amp, and the other in the negative, and turning it on.

The coils read 1.5ohms per side (quad .7 in series = dual 1.4-1.5ohm), it's not blown. The tinsels are fine, because they both read the proper resistance.

Sorry - it's not the sub. Audioholic is right, it's electrical issues.

i have dual 2 ohm sub, should it read 1.5? i wired it in parrallel

 

[NDMstang65 10+ year member]

each coil should read 1.5...they use a quad .7 coil in series for a dual "2" nominal....

225 pixels man, not 264 //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Yes, I'm anal like that //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thank You.

Sorry to thread jack but ****... I thought I was the only one having these popping problems . I recently installed my XXX 12" w/ a Soundstream VanGogh 1600w in a ported box. Everything's wired up properly w/ zero gage wiring and a 2 farad cap. Also, my stock BMW battery is pretty big and sits in the back of the trunk. I don't know what's the problem //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I have the exact same set up and my s hit rocks. No popping noises what so ever, just amazingly loud clarity. How is it sounding otherwise?

I would check all the wiring and you will have to upgrade your electrical system as well. How many amps is your stock Alternator. And this may sound like a dumb question but you did use both the power inputs correct? I've known people on thos board who have only used one and thinks the other one is to run power to another amp.

yes but i wired the dual 2 in parallel for 1 ohm, should it exactly read 1 ohm, because im getting 1.5ohms

Rated coil impedance is nominal. Its rarely the exact number advertised when actually measured. 1/4ohm deviation from nominal doesn't sound unusual to me.

 

[bamaboy 5,000+ posts]

so getting 1.5ohms for dual 2 wired in parallel for 1ohm is okay?

 

[audioholic 5,000+ posts]

Just pull the sub and measure each coil if you are that concerned about it. Then we can compare your actual impedance to the impedance of one of my XXX's if you want.
