Can my la590 American legacy 2 series 800 watt handle Boss CX122 Chaos Exxtreme 12-Inch Subwoofer 4-Ohm Voice Coils??


It is only stable to 4 ohm mono(which is 400 watts RMS or a bit less not the max rating of 800 watts which is a PMPO rating).

Your Sub would have to be wired in series(8 ohm final load, if you wire it in parallel 2 ohm-you will fry that amp).

Volfenhag ZX4725 i am buying this subwoofer and


No the LOWER the resistance the MORE Output or Draw, If say it is 100 Watts into 4 Ohms, if you used a 2 ohm speaker it would draw 200 watts.(only if capable of delivering that amount of power) The LOWER the Resistance, the HIGHER the Current Draw. WATTS = AMPS x VOLTS. (This is not strictly true with amplifiers output though, as it is an AC Current, and a "Reactive" load, it has, Inductance, Capacitance and Resistance, all in one.and is worked out via a Formula) see below. http://en.wikipedia.org/wiki/Audio_power

http://www.hometheaterhifi.com/volume_1_1/v1n1spk.html

Now with Dual Voice Coils, Essentially, you can think of these speakers as TWO speakers in ONE enclosure. As such, They are basically TWO Speakers. Please see the website below it explains everything for you. http://www.diyaudioandvideo.com/FAQ/Wiring/
Everything is a function of Resistance and Ohms law.
Current (I) = Voltage (E) divided by Resistance(R).
Voltage = Current Multiplied by Resistance.
Resistance = Voltage divides by Current.

Help with hookup


I am assuming you are driving a sub-woofer. Run the amp bridged at 4 ohms. So a DVC(dual voice coil) 8 ohm sub with voice coils wired in parallel would give you a 4 ohm load. Just make sure the sub can handle at least 300 Watts Peak.

I have a 2500 watt legacy ice amp and im tryin to hook it up to two 900 watt rms soundstreams daul voice coils whats the best way


If you amp is 1 ohm stable you can run + to +, - to - on each voice coil. Wire them into the box. Run +'s to +'s on amp, - to - on amp

Other wise. If it is a 2 ohm stable amp, you run two 4 ohm dual voice coils to the amp + -, + -

If the subwoofers are 2 ohm, run + - on only one voice coil to the box for each and run + -, +- for 2 ohm load on amp or + - bridged for 1 ohm load.

I hope that makes sense.

Why does the kenwood kac-9103d has two sets of terminals if its a one channel amp so how do i hook up a dual 12 phoniex gold 1200 watt sub to it


Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

Wireing diagrams


Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.

I have a 4 channel amp


This amp will not give you 1000 watts of real power. From the specs I've found, it can produce 55w RMS x 4. Bridged, that would be 110w RMS x 2. The most you could get into a dual voice coil woofer would be ~220w RMS.

How should I wire my 3 subs to the 500/1 amp???????


First of all how many ohm's are each subwoofer rated at . Are the subwoofers dual voice coil or single voice coil. Once I know that I can help you. I think the JL amp is not recommended below a 2ohm load.

Amp Will Not Stop Overheating


You say you have 2 p312d2 subs. Ok so the d2 stands for dual 2homs (2 X 2homs voice coils per sub) , conecting in parallel the 2 voice coils of only one sub will create 1hom load to the amp, and if your amp is 2homs stable per chanel that means you are lowering too much your homs causing the overhwating to it.
