HOw much resistance is my amp truly seeing?

[Rasheedhos]

i have 2 dual 2 ohm voice coil. if both subs are wired in series then parrell to one channel how much is my amp really seeing ???/ they are dvc old school strokers

2 Ohms nominal but there's no way to tell actual resistance outside of throwing a DMM on it and taking a reading.

 

[Rasheedhos]

is it possible that it could be 3 ohms?

no

 

[haole_boy]

yeah. put a dmm into the terminals on the box when you have the subs installed.

you wanna know what it is music off or when the subs are playing?

well my amp is only stable at 4 ohms mono (us amps 2000x)..... my subs are dual 2 ohms.... the amp can take 3 ohm but it can't take 2 ohm.. Since i wanna run it while it's playing to see if the amp could handel it while playing music

If you are talking about the overall impedance when playing music, you are going to be close to 2 ohms for the minimum impedance.

If you measure with a DMM, you will get DC resistance; not much help for your amp load playing music.

If you are burping, you can easily use a resistor in series with the subs to find the voltage drop and current at the frequency you will play. From this, you can determine the impedance at that frequency. But, you are only measuring at that frequency. I guess you could measure every frequency and find the minimum. . .

chart your impeadance either like stated above or with a clamp meter.

 

[Rasheedhos]

it's not for burps for music

i have 2 2000x and 4 dual 2 ohm strokers is there any other way they can be wired to i can get the full 1000 watts to each sub?

ok, chart your impeadance and see how low it drops within your frequincy range.

 

[Rasheedhos]

when playing and hitting low notes are the impedence suppose to raise or drop?

depends on the driver and the box design. . . .
