Dis connect the sub then turn it on, don't let the wires touch or it will have a problem. If your lucky, it's just your sub that needs replaced. If not, your amp needs serviced. Rockford use to have a three year warranty... I'm not sure what they have now since mass merchants beat up the line. Hope this helps

Not sure if you are getting two subs or single?

Anyways, amp is rated at 800 watts and probably under rated so it will push sub. Remember that you don't need to worry about max power, rather focus on RMS power rating.

It can't be done unless you choose to include some power resistors in your circuit for impedance matching. The problem with that would be some of your power will be lost in the form of heat across the resistors without the benefit of contributing any sound.

Also, the amplifier's damping factor will be compromised, so you may notice a loss in sound clarity. It's possible that you might not easily tell with subwoofers, depending on the enclosures they're mounted in, and whether they're isolated in a trunk vs being in the same airspace with you (hatchback, SUV, or pickup truck).

Amp makes noise. I am purchaseing a new amp


Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

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

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.

Rockford Fosgate 501bd question


that amp should work fine with those speakers,just make sure that they(speakers)are wired for 2 ohms.at 500-600watts coming from amp, you should be getting 250-300 watts per speaker,just dont crank your gain too high on the amp.
