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!

    Yes, I know how to bridge the amp, I am wondering how I should wire the SUB, go to this site, it shows the two methods I am inquiring about.

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.

Can I run 2 12 inch 2ohm fosgate and a 4 ohm 12 on a rockford fosgate 401s 1200 watt amp

Yes. Wire the two 2 Ohm speakers in series and connect them to one channel. Connect the 4 Ohm speaker into the other channel. This will give you a balanced 4 Ohm load on each channel.

What kind of amp can adequately power P112 S8 subs

you shouldnt run it at 8 ohm it shows what ohms it can handle . to run it at 1 ohm you would need 2 subs to do this. and no i wouldnt run an 8 ohm sub on the amp.

Im looking at this rockford fosgate p700-1bd amp brand new for $300 it comes with a birth sheet it says 750 rms on a 1ohm load. i cant find any reviews about it 225 rms x 1 @ 4-Ohms 450 rms x 1 @ 2-Ohms...

You can't go wrong with Rockford, in my opinion. Everything they make is well built and high quality. I personally have two Rockford p500-1bd amps hooked up to four 12 inch subs in my car and those amps make those subs slam. I have them wired down to 1 ohm and the specs say that they should be pushing 500 rms a piece at 1 ohm so that p700-1bd amp really packs a punch. Depending on what you're hooking up to that amp I would defenitely recommend it to you. - Ryan in Alaska

Which subs to use with the rf punch 8002

You should get the dual 4 ohm version of subs and wire them both in parrallel and series for a 4 ohm load to that amp, Bridge the amp and your subs should be seeing about 960 watts true rms.

Rockford fosgate 800 a2 amp power?

Hello desperate2le,

Watts delivered is a function of the voltage times the current. If the amp was 100 percent efficient, it would need 33 amps at 12V for 400 watts. At 14.4V, it would only need 28 amps. Of course, amplifiers are NOT 100 percent efficient, only about 50-60 percent in many cases, but somewhat higher for monoblocks, maybe 80-90 percent. So you're looking at a fuse in the 60-80A range. In the absense of a specific fuse size from the manufacturer, I'd start the primary fuse at a 60A and if the amp blows it on power up/immediately/frequently, move up to an 80A.

All of the Rockford-Fosgate 2-channel bridgeables I've ever seen show using the left positive (+) and the right negative (-) for bridging. But if it's not shown right on the amp, I'd call or email RF for the correct connection. The new amps do show it.

Hope this helps.

Not a problem just a question

  • 100 watts RMS x 2 at 4 ohms
  • 200 watts RMS x 2 at 2 ohms
  • 400 watts RMS x 1 at 4 ohms in bridged mode
  • stereo or bridged mono output
  • 4-ohm stable in bridged mode
  • Tri-Way capable
  • requires 8-gauge power and ground leads — wiring and hardware not included with amplifier
  • 50-250 Hz high-pass/low-pass (12 dB/octave) crossovers
  • wired remote included for fingertip control of Punch Bass (0-18 dB boost at 45 Hz)
  • MOSFET power supply and output devices
  • MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability
  • TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
  • Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
  • NOMAD — advanced protection circuitry for "intelligent" shutdown protection
  • speaker- and preamp-level inputs
  • 11-1/8"W x 2-3/8"H x 9-7/8"D


  • Wire your sub in bridged mode (4 ohm mono)
    + to + on amplifier
    - to - on amplifier
    (using bridging terminals)

    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

    Bridging 800a4

    That all depends upon whether or not the sub you are running has dual voice coils or just a single voice coil. The 800a4 is a four channel amp; thus the only way you can bridge it will be 3 channel or 2 channel. If you are running a dual voice coil sub then you can wire the amp two channel and get 400 watts x 2 @ 4 ohms. Make sure that you sub can handle this kind of power though.

    Here are the specs:
    4 x 100 @ 4 ohms (13.8V - <0.05% THD)
    4 x 200 @ 2 ohms (13.8V - <0.10% THD)
    2 x 400 @ 4 ohms bridged (13.8V - <0.10% THD)
    Fuse: External 60A
