I have a 500x1 Rockford Fosgate Prime Class-D amp. Should I get the 2 Ohm or 4 Ohm version of this sub?

I run that same amp with the 2ohm sub, it is perfect sounds awesome and they both should run forever set up properly.

4 ohms because you can low to two omhs the sub conecting positive with positive and negative and negative ( the sub has double coils)

For that I'll get the 2 Ohm. But you can get the 4 Ohm and Put only 2 ohm later get a 2000 watt amp and put the 4 Ohm I'll do that maybe what you think? Thus that answer your question Alex

If you're getting one sub, get the one with dual 4-ohm voice coils. Wire them in parallel for a 2-ohm load on the amplifier for 500w to the one sub. If you're getting two subs, get the dual 2-ohm version. Wire the voice coils in series for 4 ohms per sub, then wire them in parallel to the amp for an end load on the amp of 2 ohms. This will give you 250w per sub.

I believe that is a 2 ohm stable amp so I would go with the 2 ohm speaker dual voice coil and look up the voice coil wiring online one way is seires and the other parallel make sure you wire the back of the speaker right one way is 2 ohm and other less than 1 ohm make sure its wired 2 ohm and that would give you the max watts out of your amp the other way less that 1 ohm would overheat your amp.

You'd be better off with this amp: Rockford Fosgate R500X1D Prime 1-Channel Class D Amplifier

If it is dual 4 ohm wire it in parallel and it will be a 2 ohm load on the amp which is 500 rms which should match it perfect

First, get the p3d4 you have more options with this sub. Secondly the p series subs are ( certified compliance ) meaning they do what they say- but under rated I'm running 2 p3d4 12's with a brutus elite 2100 at one ohm stable that's 2100 watts each

yup, i got the 2x version on a 4000watt demon series pa amp. 1 15 rocks better than all of my friends multiples of subs, his setup was 2 12in alpine type r's not sure on the amp but it blows almost all competitionn out of the water. bought it over a year ago still bumps like the first day i got it. loud, reliable, and looks nice too

Lower ohm allow you to put more power into the sub without blowing it. A 2ohm amp will work fine for anything higher than 2ohm as well. I would suggest getting a amp that is 1 or 1/2 ohm stable so you can wire the two coils down and get more power into in. If you are going to use your amp either make sure it has 4 outputs or youll have to wire the 2ohm up to 4ohm. Regardless you always want lower ohms but your amp must be able to handle it.

Can i use this amp for a Rockford Fosgate Punch P3D4-15 15" 600 Watt RMS at 4 Ohm ??

2 ohm, I have dual 12s both running 2 ohms with a 3000 watt amp, sounds amazing and I'm still breaking it in, but 2 ohm in my eyes is for more than one sub to divi the power more equally

These woofers have been redesigned with great improvements overall. I used the older version with a 250 watt rms Monolithic amp with no problems @ 4 Ohms. I'm sure you will be pushing the limits at 5oo W rms @2 ohms, but the speaker will be agile and fast and you will not have problems if you don't crank it to max levels. The safer route If you will be cranking hard, will be to move to the next level which is the P2D4-12 rated at 800W @ 2 or 4 ohm, I will not be as responsive, but it can handle 800W!

Oh yeah definately its two ohm stable but if your sub is only 300 watts it may just be to powerful and blow your sub this amp is serious

Ive got mine hooked to a pioneer premier 12 in 2ohms and its really really loud I have to keep the subwoofer line way down. Im sure it would be similar for yours in 4ohms its a very strong amp. Works great ive had a few different kenwood amps and they always perform.

Yes like some of the others have said the differences are one is a 10 inch dual 4 ohm and theother is the larger 12 inch dual 2 ohm. Personally I prefer a lower ohm sub because of how powerful the lows are with lower ohms. However the lower the ohm the more expensive your setup will get because lower ohms can take more power but have slightly less sound quality and vice versa for higher ohm setups so it really boils down to what you prefer both are winning subs if you ask me or any of my friends great buy

Eric, go with the Rockford Fosgate Prime 250x1 mono block amp. It has a very small footprint, very affordable, and these amps, in my opinion, are still one of the best on the market. These amps are always underrated, come with an actual RMS rating tested by the manufacturer, and will be plenty of power to push a 10" sub. It will not disappoint.

I down graded from 2 Fosgate P3's to a single sub to get a little bit of trunk space back (2006 Sentra). I think the sub sounds damn good for just one. I have it in a 1.25 sealed box, hooked up to a Alpine 500W mono amp turned only to half gain with a remote bass knob. I have nothing negative to say about the sub.

I dont know if it will help or not, but I have a fosgate 500.1 running mine. A single twelve enclosure. I'm guessing your amp question is referring to a 5 channel. In my opinion a 600 watt 5 channel would struggle to run this sub. It all depends on how the wattage is distributed. A four channel for your door speakers and a mono block for your sub. Can't go wrong

Bought these and heard very bad about them. I went with a rockford fosgate p3 12" single sub in a sealed box wired down to 2 ohms. Im heard from a distance with just one

Why would u want this sub wired at 8 ohms, if anything u should wire it down to 2 ohms
