    yes both of speaker is 1200 watt , also the speaker is Dual 4 ohm High-Temp KSV Voice Coils

    yes but the amp isn't 1200 watt. the that i had is 300 wat rms so how i wire for it.

    Ok on the amp is the at what resistance is the 1200 watts. should say at 2 0hm or four ohm stable. also the speakers are they 2 ohm or 4 ohm.

If the amp is 1200 watts at 2 ohm stable you will want to set up the speakers as parrallel and bridge the amp. That means conncect the speakers with + to + and - to -. Look at the amp connections. Usually thereare connects that look like this:
+ -
+ - + -

If yours look like this use the diagram on top. You will use the + for the left ouput on the amp to the right - on the amp. This will allow you to use all the power from the amp. Be sure to lower the gain as to not pop the speakers or amp.

I have a kicker 10 comp d dvc 4 ohm 600 watt. How do I run a obcon 2000i 2 channel amp to it


You can't. Total mismatch of power and impedance.

You need a mono amp that can push the RMS watts of the sub @ 2 ohm (sub wired parallel).

Which amplifier i should use with JBL CS-1205T


this sub woofer tube has a rms rating of 275 watts... try using a kicker or orion 600 watt mono amp to run this. the brand name is what tell you about how good an amp is for instance the names i just mentioned rate their amp by standard play frenquencies where as other lower brand names rate their amps by the max out put on certain subs at certain frequencies which may lower their impedance and create more power although you will never play your sub at those frequencies. as for the max power of your sub of 1100 watts that is more than like only at a certain frequency so always only double your rms rating of your sub to find max power handling.

Finding the best amplifier


Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

i would wire the coils of each sub in series which would yield an 8 ohm resistive load per sub - and then wire the subs in parallel to the amp which would bring the resistance back to 4 ohms for a bridged load which will give you max power handling from the subs and draw the full power of the amp at the same time

Is amp big enough for speakers


Hello,

To run 2 subs, the amp would be a little small. The subs will run OK, they just won't be very loud.

It's usually better to compare and match up the RMS power rather than the peak power. The Sony XS-L10P5B sub has a peak power handling figure of 1200 watts, but the RMS is 300 watts. The Sony XM-ZZR3301 monoblock amp puts out 1100 watts peak, but only 330 watts RMS. They would work great together, 1 sub, 1 amp. But if you add another sub, each one would only be getting about 165 watts. They'd work OK, just not as loud as they could be.

Hope this helps!

Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps

Subwoofers seized up wont play


putting too much power to the subwoofer......i just blew mine now.....it was a 1600 kenwood exelon 500 rms watt sub.....powered with insignia 600 watt 2 channel.......ran 600 watt rms though......cooked it ......so if you can underpower it....just bc it sez 1600w doesnt mean you have to match it just dont go over!
