It certainly can, and it MAY provide too MUCH power to that sub. That's a lot of amp.

SOURCE: one hits harder then other

Check the Polarity on the subs, you might have to invert one. Best way i know of to test is get a BASS CD -=download a bass test cd...legally of course=- and check for a test that will just flutter the speakers in and out and see if they both go in and out in the same way, if one is in and the other is out that could be your problem

SOURCE: bridging to 12 inch kicker competition subs to my 1000 watt alpine 4 channel amp

I'm a bit confused. For Alpine amps, the "M" prefix is for monoblock (aka single channel) amps and the "F" prefix is for multichannel amps. The only M550 I find is an MRD-M550, which is a monoblock, not a 4 channel like you say.
Unfortunately, I can't give you accurate help until we know weather it's truly 1 channel or 4 channel. Then I'll be glad to help!

SOURCE: Rockford Punch HE2 wiring question.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

SOURCE: I have a 12 inch ORION HCCA dvc, 4ohm sub. My

Halving the impedance will draw twice the current. You could technically get a 3 Db more power since the peak voltage will remain the same. BUT if the magnet structure is not intended to use that cone design, the magnet difference MAY not give you 2 ohms.

In fact, if the designed magnetic flux were smaller, you could wind up with a 1 ohm speaker.

trying to get that much power is really kind of silly as even 50 watts with efficient speakers will exceed safe levels of sound that will not cause damage to your ears.

As you push an amp up in power, usually distortion will increase as well.

Can i use a 300 watt amp for 2, 800 watt woofers

yes, but you would not get the same performance as you would if you gave them the suggested power. I have found that it is always better to use a more powerful amp than your subs are rated for (as long as it is clean, high quality, low distortion power). I have had the best luck with name brand amps (kicker,rockford fosgate,phoenix gold,etc...). I hope this will be helpful to you.

I Have a Sony Xplod 800 watt amp and 2 12 inch Sony Xplod subs

You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.

I have two 12 inch rockford p1 punches powered by an 800 watt sony explode amp (2 Channel) and i want to install another 15 inch kicker with a 1200 watt amp not sure the model, i got it from a friend and...

I have a similar setup & I just run the second amp straight off the other amp by running positive & remote wires directly from 1 amps positive & remote inputs to the others amps inputs. But my head unit has RCA inputs, (sub in & front & rear inputs) so from my 4 channel amp I run 2 6 inch alpine S's to the front to the front RCA inputs of the head unit, & 2 Pioneer 440w 6x9 inch speakers to the rear inputs. & my 800w 12 inch sub from my 2 channel amp to the sub woofer inputs on the head unit. Has blown my eardrums for nearly 12 months now great stuff! Hope this has helped

I have 3 hifonics zeus Size: 12 inch Impedance: Single 4 Ohms Peak Power Handling: 800 watts RMS Power Handling: 400 watts Sensitivity: 89.9 dB Aluminum Cast Basket American Spider For Reliable Performance...

Hello king3132,

Three 4 ohm subs can be wired parallel for a 1.34 ohm final load or series for a 12 ohm load. If you have the channels of the amp bridged, I hope that the subs are connected in series because the Sony XM-2200GTX is NOT rated for or stable at 1.34 ohms. It's only stable down to 4 ohms.

You definitely will not get the maximum potential of the subs from that amp. They can handle 400 watts RMS each (total 1,200 watts) and the amp is only capable of 500 watts RMS into 4 ohms (less at higher impedance), so each sub could only be getting a maximum of 166.6 watts RMS.

Hope this helps.

Bass not Very deep

250 watts rms seems a little low for a 12 inch woofer, a 500 or higher will likely fix your problem. Specific model numbers and the type of enclosure you have will allow a more specific answer.

Problem when hooking two 12 inch subs to one amp

the amp is no where near strong enough that sound you hear is called hard clipping and it will destroy your subs in minutes. depending on what model JL subs you have I can sell you a better amp.
