Why is my system playing at 8-10 Ohms instead of 1 Ohm like it should be?


Recommended Posts

Okay so I have two dual 4 ohm woofers wired like this

But when i hook my DMM up to any of the coils or the amp it says that its anywhere from 8-10 ohms?

I have the subs reverse mounted and on the deck (Pioneer AVH-P4300DVD) i have the sub polarity set to "reverse". Any ideas???

maybe .8-1.0 ohm????

How do the Japanese feel about bass?

You know that since 03/11/11

Progene? I just saw that stuff on CNN. They said it makes your junk shrink all up. lol.

im pretty sure the op wont even notice if it gets even smaller.

Do you have them connected to the amp while measuring?

If yes, disconnect them and measure.

If no, better:

Check your wiring

Check one coils at a time (disconnected)

Check you meter and settings

Current system:

1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s

Previous systems:

2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz.

1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

Maybe the dmm is on the wrong setting or turn off the deck and check it. Dont check it if theres power going through the wires those cheap multimeters cant handle it. Or one of your voice coils are damaged. GL

same thing happened yo me before, instead of 1 ohm it showed 10 ohm load.

Your subs are at 1 ohm, try using different DMM and check thru different parts of wire.

Okay thank you! Ill go pick up a different DMM soon. The one im using is really old but it still measures the speakers coils as being around 4 ohms each

before you buy new one, try sticking DMM in different part of the wire.
