It is the impedence (coil resistence)normally sub component (drivers)are in 8 ohms impedence.2 in parralel is 4 ohms and 4 in parralel makes it 2 ohms.
The difference between 2 ohms and 4 ohms is 2 ohms.
Speakers need to be matched to the amplifier. This will allow maximum dynamic range of power before distortion. In extreme cases, overloading an amplifier can damage it. A 4 ohm speaker requires a certain voltage and current to achieve a certain power. A 2 ohm speaker will require less voltage or greater current (ratio the square root of 2) to achieve the same power. The decision is based on the system design, including the design of the cross-over network, if there is one.
This depends on the model you have some are 200-500 watts and they also make 2 & 4 ohm subs.
Hook all the negatives together, and hook all the positives together. you would have 2 wires for each. one from the amp to the first sub, and another going from the first sub to the second.
Yes
Though it is tempting to say the difference is 2 ohms (8 ohms minus 2 ohms equals 6 ohms), lets look at some things. The 6 ohms is 3/4ths the resistance of the 8 ohms. If the resistances are loads, the 6 ohm load will draw 1/3rd more current than the 8 ohm load. The 8 ohm load will draw 3/4ths as much as the 6 ohm load. Those are some differences between 6 ohms and 8 ohms.
What you need to know is the RMS power rating and ohms of the subwoofer. (Example; RMS is 300 watts and it is a 2 ohm sub. This is what you would need. You have 2 subs so a total of 600 watts. So you want an amp with a max power rating of 600 watts, but he is the tricky part. They were 2 ohm subs. So your amp needs to be 2 ohm stable. No there all not 90% of amps are only 4 ohm stable.)
To wire a Rockford Fosgate T500.2 amplifier to a 2 ohm load, you will need to connect two 4 ohm subwoofers in parallel. Each subwoofer's positive terminal should be connected to the amplifier's positive output terminal, and each subwoofer's negative terminal should be connected to the amplifier's negative output terminal. This will create a 2 ohm load for the amplifier. Be sure to verify the amplifier's minimum impedance requirements to ensure proper operation.
Yes, you can power two 12-inch Kicker Comp subwoofers with a JBL GTO3501 amplifier, provided the subwoofers' impedance matches the amplifier's output. The GTO3501 is capable of delivering up to 350 watts RMS at 2 ohms, which should be sufficient for the Kicker subwoofers, as long as they are wired correctly (typically in parallel for dual 4-ohm subs). Make sure to check the power handling specifications of your specific Kicker model to avoid overloading the subwoofers.
The ohm is defined as a resistance between 2 points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.
Yes, that is correct a punch75hd can push 2 15 inch subwoofers
Your SUV comes with a 8" subwoofer from the factory. Most likely a 4-ohm sub. I know the Kicker Comp VT 8" will bolt right in and you can get them either 2-ohm or 4-ohm. You would probably notice quite a difference putting a 2-ohm in.
