Question about Rockford Fosgate HE2 RFP4212 Car Subwoofer

1 Answer

Rockford Punch HE2 wiring question.

I have a Rockford Fosgate HE2 12 inch dual channel 4 ohm sub with 400 rms and 800 peak power. I also have a Rockford Punch 401s 1200 watt amp. The amp has stereo and bridged output options. I found a wiring diagram on Rockford's site, and I am wondering which setup is the best for my system? http://www.rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=1&woofer_imp=4
Thanks for your help!

    It outputs 400 watts at 4 ohms bridged. So which configuration should I have it set up with from the website? Now I have it set up as: the input + and - are plugged into the first jacks, and then I have another wire running to the back to the other + and - jacks on the sub. So it is just wired in parallel, would this make the power any different? This is not shown on the website though. I want the best boom for the wiring.

    Thanks for the update!

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.

    Into the amp you need to run the + wire to one channel then the - wire to the other chanel. This will give you more power.

    If your amp can be 2 ohms stable do this wiring and hook them in series.

Look for a 4-channel amp that pushes 50 watts RMS @ 4 ohm.
Make sure the amp is CEA-2006 compliant.
Ignore peak or max watts as these are arbitrary numbers.

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.

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.

Punch he 4 ohm 200 rms 400 peak


the winding on the voice coil are coated with a varnish to keep the from shorting to each other. If the sub is drivin to hard or the voice coil is not vented properly. the voice coil windings will get so hot the varnish will melt or someting get sticky. When you quit playing the sub, say overnight the varnish cools and acts like a glue and will cause the voice coil to stick to the basket of the speaker. Repair just would not be worth the money or the time. Plus when a speaker reaches thid stage. It could eaisily fall to short and burn out your amplifier.
