Hey guys i have a volfenhag zx-8400 this is the spec for the amp:

* Number of Channels 2
* RMS Power (4 ohms) 200 watts x 2 . channels
* RMS Power (2 ohms) 300 watts x 2 channels
* RMS Power (1 ohm) Not Stable
* Bridged RMS Power 600 watts x 1 channel
* Peak Power Output 2000 watts
* Minimum Impedance Unbridged 2 ohms
* Minimum Impedance Bridged 4 ohms
* THD at Rated RMS Power 0.1%
* Speaker Level Inputs No
* Preamp Outputs Yes (1 Pair)
* Built-in Crossover Yes - HP / LP / Full
* Bass Boost 0 - 18 dB
* Signal-to-Noise Ratio N/A
* Fan Cooled Yes
* Fuse Rating 40 A x 2
* High-Pass Crossover Frequency 50 - 1 k Hz
* Low-Pass Crossover Frequency 30 - 500 Hz
* Subsonic Filter N/A
* Channel Separation N/A
* Bass/Gain Remote Yes
My question is I have two KICKER CVR 12" 2 OHMS percoil. So i was wondering what is the best way to connect it to the amp? I currently connected it so it would produce 8 ohm resistance. But my amp can only support 4 ohm when its briged. So is 8 ohm the last hope?

Thanks alot

is the kicker a Dual voice coil setup?

jishan

ya it is a dual voice coil setup

IF that's the case, then yes..8ohm is the lowest you can go. Wire everything up in series.

Wire the voice coil on each speaker in series for a 4 ohm load and use the 2 channel setup with each channel showing a 4 ohm load.

You can also wire one speakers voice coils in series for 4 ohm load and the other in parallel for 1 ohm load. Then wire the 2 in series for 5 ohm load. Not the best way to do it, but it can work.

If the amp is consistent (doubt a wolfenhag falls in that category), then wiring it up to 8ohm bridged or 4ohm independently should be the same. Either way works fine. But I wouldn't suggest running one sub at one resistance and the other at a different value. One sub is going to overpower the other.

Not saying it works perfect, but in theory, a circuit with 2 or more resistors show the same voltage at each resistor. Signals sent through speaker wire is nothing more than voltages that cause the electromagnet within the speaker (voive coil) to react to the stationary magnet. So, each speaker would see the same voltage. Again, this is in theory. I personally would not wire that setup, but I do know of people in the audio industry that say it is ok.
