Almost any amplifier amp would push a 400 watt sub. try to stick with a name brand, and steer away from no name brands like boss, jensen, etc.you will only need a 2 channel amp to run your sub.you will need a second amp to run your 6x9'sor you could get a 5 channel amp, and run all your speakers, and the 5th channel for your sub

Usually a power rating is a power rating, 1000watt rating is a thousand watt rating. The amp will put out 900 watts at 2 ohms.

Use good quality wires-- the cost is the factor for high connectivity with low resistance- You can bridge the two sub's in parallel to the 2 ohms output of the amp. Please be careful to see the likeness of polarity of the subs to the amp. or lese you will get a phase difference resulting in poor low frequncy.

How to wire a crossfire vr602 2 channel amp at 4ohm and 2ohm


I would be more worried about the amp than the speakers, those subs should handle the watts with no problem. The problem will be in the amps ability to remain working with a bridged 2 ohm load. It may not even stay on without going into protect mode with a 2 ohm load. If it does stay on then it may get really hot and shut off from the heat off of the Mosfett Transistors, or it could burn the Mosfetts from driving them too hard. Basically it's your choice, run your amp hard and gain more volume or run it with slightly less sound and have a cleaner sounding more stable amp that will stay on and have less chance of being damaged. If it's not loud enough the best thing to do is buy a different amp that better suits your needs and fits the application. In your case a 2 ohm stable Mono amp is going to be your best bet or a 4 channel amp bridged into 2 channels and run with 4 ohms on each channel. Or another exact matching amp like your 2 channel amp bridge them both and have each powering 1 of your 4 ohm subs. I used two VR mono amps to power my two 12" 4 ohm subs for a few years

Hifonics colossus-ltd dual monoblock amp does not have much output, running a cerwin vega stroker dual 2 ohm sub wired 4 ohm load bridged


Bridge at 4ohms your only getting 600watts rms. You will need to bridge at 1ohm (parallel) and adjust the gain accordingly. This will give it 1600 watts rms. If you would of had a dual 4ohm sub, then you could of bridged it at 2ohms mono, but you can't you have to go either 1 ohm or 4ohm. I believe it's not getting enough power.

Best way to connect a 15'' kicker cvr15 4 ohm dvc [single sealed box] and a volfenhag zx-4712 1000w 12'' 4ohm+4ohm dvc to my pyle 885 1000w 4 ch. bridgeable amp and how to wire the voice coils that are in...


best way is to just run the volfenhag with a set of wires for 2 channells(one set per coil) left and right @ 4 ohms per channell. The CVRs you can parallel the coils(2 ohms) and run a set from each sub to the amp in stereo left and right. This will give the kickers a little more juice than the 12 but should be fine.

Not enough Amp?


You should still get sound even with small amps but it would be rather weak. Check first the source of the signal. Test with different sources to be sure. Check for loose connections.

Can this power a subwoofer and what is the rms wattage


Hello crucible19,

The Alpine MRP-F240 is a 4-channel amp that outputs 40 watts RMS per channel. It is more suited for powering normal speakers, but since it is bridgeable, you could power a small sub by bridging 2 of the channels.

Hope this helps.

forget hooking this on a subwoofer. this amp produces only 50 watts per channel at 4ohms or 70 watts per channel at 2 ohms RMS...
If you try bridging the sub, it will only give out maybe 100watts bridged.
So..... if your sub is, lets say 1000watts RMS, youre just going to bust your amplifier to smoke...
Find a more decent and powerful amp. This amp is only intended for separates and lowend subs with an RMS of 80 to 150 watts

I have 2 jl-w6 subs n a orion hcca 250 amp how do i run wirering


Hello brianmitchel,

From what I am able to determine, the Orion HCCA250 is a bridgeable 2-channel amp that is stable to 1ohm when bridged and outputs 800 watts RMS into that load.

The JL W6's in both 10" and 12" versions are dual voice coil with 4ohm coils so they can be wired to present either an 8ohm load (series) or a 2ohm load (parallel). They can handle 600 watts RMS.

With this combination, the best configuration would be to wire the sub voice coils in parallel for a 2ohm load and then parallel both subs to the amp bridged terminals for a final impedance of 1ohm. The subs will each be getting 400 watts.

In any event, I would not recommend running subs in series. There is some evidence for distortion being caused by something termed "back EMF".

Hope this helps.

What amp do i need to power a Polk Audio db1040DVCin brigded connection, i only plan to run one sub, i want to bridge the sub for better sound quality, and i'm buying straight polk, what do i need


Hello oran1891,

OK, you don't bridge subs. You bridge amps, if they are capable of being bridged (not all are).

Bridging is a method of connecting the channels of a multi-channel amp in such a way that the amp delivers the output of 2 stereo channels into a single mono load.

The Polk DB1040DVC is a sub with dual 4ohm voice coils. You can wire the voice coils to present a final 2ohm load (parallel) or a final 8ohm load (series). The rated power range is 50-270 watts RMS. Since you can parallel the voice coils and have them present a 2ohm load to the amp, you are looking for an amp that provides a minimum of 50 and a maximum of 270 (round it up to 300) watts into a 2ohm load. The Rockford-Fosgate Punch 300.1 shown here for $170 seems tailor made for your Sub. If you can make do with less power and want to spend a little less money, the Orion Cobalt CO500.1 will deliver 250 watts RMS at 2ohms and you can buy it for $140. The punch is a better deal. If you decide to add another sub later, it will power them both with 150 watts each, a little low, but still decent. If you want a 2-channel bridgeable amp, I'd recommend the Kicker 08DX3002 shown here for $200. Note that in bridged mode, it is not stable at 2ohms, only down to 4ohms.

Hope this helps.

Hi,just bought a 6x9 jbl gto937 speakers for my car,each speaker is 100watt rms and 300 max .Can anybody advice on what amplifier should i get for them?I know i can run them without any amp but think they...


Pyramid makes the PB series of amps. I have one that's driving a Sub.
The PB 700 puts out rms 60watts x 2 @ 2ohms, which gives you some "headroom" for your speakers. You don't want to over drive speakers with , for example, a 1000 watts for 100 watt speakers, because that's a good way to blow your speakers.
There are many brands and models of amps that will fit your speakers. Just make sure the amp will drive 2ohm speakers, since your jbl's are rated at 2ohm impedance.
You may want to consider adding a Sub woofer to your setup. A single Sub would fill in the low end very nicely. If you got a 4 channel amp, then two channels will drive your jbl's, and you can bridge the other two channels to drive the Sub. That would be a kick'n sound!
Just make sure the amp is bridgeable
For example, the Pyramid PB 1200 is a 4 channel, bridgeable amp. This particular amp will drive the 2ohm jbl's, but you would want a 4 or 8 ohm Sub connected to the bridged channels.

Connecting a subwoofer to a mono amp that has 2 sets of terminals


ok this gets confusing sometimes. Ok first look to see what ohm your subs are. If you have a dual 4 ohm sub When you run that on sub + to + and - to - then that will make that sub 2 ohm. its different on ohm if the sub is say a 8 ohm then putting the wires that way will bring that sub to 4 ohm. Now lets say you have 2 subs that are dual 4 ohm and wire both of them + to + and - to - and go bridge the amp which would be both wires from sub both + together and both - wired bridge on the amp will make it a 1 ohm to the amp. Please post what ohm your subs are and i can tell you alittle more about it
